Abstract

GeoDCAT-AP is an extension of the DCAT application profile for data portals in Europe ([[[DCAT-AP-3]]]) for describing geospatial datasets, dataset series, and services. Its basic use case is to make spatial datasets, dataset series, and services searchable on general data portals, thereby making geospatial information better findable across borders and sectors. For this purpose, GeoDCAT-AP provides an RDF vocabulary and the corresponding RDF syntax binding for the union of metadata elements of the core profile of ISO 19115:2003 [[ISO-19115]], those defined in the framework of the INSPIRE Directive [[INSPIRE-DIR]] of the European Union and those defined in the Technical Guidance for the implementation of INSPIRE dataset and service metadata based on ISO/TS 19139:2007 [[INSPIRE-MD]].

Introduction

This document contains version 3.0.0 of the specification for GeoDCAT-AP, an extension of the DCAT application profile for data portals in Europe [[DCAT-AP-3]] for describing geospatial datasets, dataset series, and services.

Its basic use case is to make spatial datasets, dataset series, and services searchable on general data portals, thereby making geospatial information better findable across borders and sectors. For this purpose, GeoDCAT-AP provides an RDF vocabulary and the corresponding RDF syntax binding for the union of metadata elements of the core profile of ISO 19115:2003 [[ISO-19115]], its XML metadata encoding standard, ISO/TS 19139:2007 [[ISO-19139]], and those defined in the framework of the INSPIRE Directive [[INSPIRE-DIR]].

The GeoDCAT-AP specification does not replace the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]] nor the INSPIRE Metadata technical guidelines [[INSPIRE-MD]] based on ISO 19115 and ISO 19119. Its purpose is to give producers and maintainers of geospatial metadata the possibility to achieve more by providing the means of an additional implementation through harmonised RDF syntax bindings used in the Open Data community. Conversion rules to RDF syntax would allow Member States to maintain their collections of INSPIRE-relevant datasets following the INSPIRE Metadata technical guidelines based on [[ISO-19115]] and [[ISO-19119]], while at the same time publishing these collections on [[DCAT-AP-3]]-conformant data portals. A conversion to an RDF representation allows additional metadata elements to be displayed on general-purposed open data portals, provided that such data portals are capable of displaying additional metadata elements. Additionally, data portals may be capable of providing machine-to-machine interfaces where additional metadata could be provided.

Context

With a view to fostering Europe's digital transformation, the European Commission is investing in frameworks and agreements to provide governments and businesses with the appropriate resources to digitalise their services. There are, for instance, building blocks available for creating a single market for data, where data flows freely within the EU and across sectors for the benefit of businesses, researchers and public administrations.

To this direction, the European Commission launched the European Data Strategy [[DataStrategy]], as part of the European Commission's priorities for 2019-2024 in order to make the EU a leader in a data-driven society.

Studies previously conducted on behalf of the European Commission (e.g., [[Vickery]]) shed light on the importance of having data findable and available in machine readable format in order to stimulate its reuse. This vision led to several legislative actions to reduce barriers and promote data sharing, such as the Open Data Directive [[OPENDATA-DIR]], which turned out to be a driving force towards a more transparent and fair access to government data.

With this regard, the wide range of (open) data portals developed by European public administrations is the result of this mission. These Web-based interfaces allow access to data by providing users means to explore a catalogue of datasets. To facilitate the sharing, discovery and re-use of the data beyond the (open) data portal, common agreements for the exchange of catalogues of datasets are needed. These interoperability agreements enable to connect (open) data catalogues into a pan-european catalogue of datasets.

The DCAT Application Profile specifies the generic agreements for (open) data portals operated by public administrations in Europe. This specification extends DCAT-AP with additional requirements for describing geospatial data.

The current document is the result of the major semantic change release process described in the Change and Release Management Policy for DCAT-AP [[DCAT-AP-CRMP]] and was built starting from GeoDCAT-AP version 2.0.0 [[GeoDCAT-AP-20201223]], with the purpose of aligning it with DCAT-AP version 3.x.x [[DCAT-AP-3]] and with version 2.2.0 of the INSPIRE Metadata Technical Guidelines for the implementation of INSPIRE dataset and service metadata based on ISO/TS 19139:2007 [[INSPIRE-MD]].

This work has been carried out in the context of the European Commission’s Interoperable Europe initiative [[INTEROPERABLE-EUROPE]].

Scope of the Application Profile

The objective of this work is to produce an updated release of GeoDCAT-AP based on requests for change coming from real-world implementations of the specification and an alignment with [[DCAT-AP-3]] and [[INSPIRE-MD]].

As [[[DCAT-AP-3]]], the Application Profile specified in this document is based on the specification of the Data Catalog Vocabulary (DCAT). DCAT is originally developed under the responsibility of the Government Linked Data Working Group [[GLD]] at W3C, and was significantly revised in 2020 by the W3C Dataset Exchange Working Group [[DXWG]]. DCAT is an RDF [[RDF11-CONCEPTS]] vocabulary designed to facilitate interoperability between data catalogues published on the Web.

The objective of this work is to produce an extension of [[DCAT-AP-3]] based on numerous requests for change coming from real-world implementations of the specification listed on the GitHub issues section since the previous release [[GeoDCAT-AP-20201223]]. For that purpose the [[DCAT-AP-3]] specification is extended with improved definitions, usage notes and usage constraints such as cardinalities for properties and the usage of controlled vocabularies. Additional classes and properties are re-used or introduced where necessary.

The work does not cover implementation issues like mechanisms for exchange of data and expected behaviour of systems implementing the Application Profile other than what is defined in the Conformance Statement in section [[[#conformance]]].

The Application Profile is intended to facilitate data exchange and therefore the classes and properties defined in this document are only relevant for the data to be exchanged; there are no requirements for communicating systems to implement specific technical environments. The only requirement is that the systems can export and import data in RDF in conformance with this Application Profile.

The only requirement is that the systems can export and import data in RDF in conformance with this Application Profile.

As mentioned in the context, the prime objective of the Application Profile is to enhance data findability and promote reusability. To achieve this goal, datasets should be coherently documented. To enable this, the Application Profile considers several essential aspects, including among others:

These are addressed with the aim to facilitate effective data reuse, allowing users to locate, understand and utilise the available data resources more efficiently.

DCAT-AP Context

Around 2010, on behalf of the European Commission the access to public sector information was studied. These studies showed that businesses and citizens faced many difficulties in finding and reusing public sector information. The studies indicated that the availability of the information in a machine-readable format as well as a thin layer of commonly agreed metadata could facilitate data cross-reference and interoperability and therefore considerably enhance its value for reuse. Therefore, to overcome these hurdles, the European Commission invested in policies [[PSI]], data interoperability [[SEMIC]] and infrastructure [[DEU]].

Interoperable Europe, within its mission to stimulate the data interoperability in Europe, manages this specification on the metadata agreements for sharing dataset descriptions between data portals. The governance is taken care by the SEMIC action within Interoperable Europe. Initially, the scope of the specification was the exchange between Open Data Portals in Europe. Although this is still at the core of the specification, DCAT-AP is not limited to publicly accessible Open Data, but can be applied to any kind of datasets. In the past decade, DCAT-AP has grown from a single specification to a whole ecosystem of related and interconnected specifications.

Revision history

The first GeoDCAT-AP specification was released in December 2015. The subsequent release 1.0.1 improved the specification. These specifications are aligned with the core profile of ISO 19115:2003 [[ISO-19115]] and those defined in the framework of the INSPIRE Directive [[INSPIRE-DIR]]. Five years later in December 2020 the second version of GeoDCAT-AP was released. W3C DCAT 2 restructured DCAT by introducing the notions of a generic Catalogued Resource of which Datasets and Data Services are special cases. As a consequence both DCAT-AP and GeoDCAT-AP required a major revision ensuring alignment between the different specifications. In 2023, the adoption of W3C DCAT 3 [[vocab-dcat-3]] triggered a new alignment for DCAT-AP, and consequently for GeoDCAT-AP. W3C DCAT 3 extends the profile with the Dataset Series notion. This document is the combination of this alignment and addressing issues raised by the community.

Notes on alignment with DCAT 3

Being an extension of [[DCAT-AP-3]], GeoDCAT-AP inherits the changes that were introduced in [[[DCAT-AP-3]]] due to the aligment with [[[vocab-dcat-3]]]. The introduction of Dataset Series in DCAT is an additive operation from semantical, data modeling perspective. Therefore the impact on existing GeoDCAT-AP 2.x, exchanges is limited. Nevertheless, publishers may face substantial impact on the existing catalogues as the new terminology for Dataset Series may require to revisit the publisher's metadata guidelines. For instance, if the publisher had chosen to document a Dataset Series as a Dataset with multiple Distributions, then the alignment with Dataset Series as expressed in this specification will require a substantial effort. This impact goes beyond the specification and is dependent on the usage of the shared information. In the context of GeoDCAT-AP and in line with the conformance expectations and [[DCAT-AP-3]], the term Dataset Series will be solely used for resources that are explicitly identified by the class Dataset Series. The situation, as mentioned, where a Dataset has multiple Distributions, will be considered as a Dataset with multiple Distributions and not as a Dataset Series. This way, receivers of GeoDCAT-AP metadata can rely on the classes to process the metadata.

The sole data model impact DCAT 3 creates, is by deprecating the use of some URIs and introducing new URIs in the DCAT namespace for the use case of Dataset versioning. As these properties are optional and since there is an equivalence between the deprecated and the new ones, catalogue owners can easily realign.

GeoDCAT-AP 3 is the result of an alignment with DCAT 3, DCAT-AP 3 and improvements to harmonise the interoperability between DCAT-AP and GeoDCAT-AP. These changes are listed in detail in the Changelog. To support the review, the changes are also highlighted on the diagram below.

  • Process information for all classes and properties specified in section [[[#quick-reference]]].
  • Process information for all controlled vocabularies specified in section [[[#controlled-vocs]]].
    • "Processing" means that receivers must accept incoming data and transparently provide these data to applications and services. It does neither imply nor prescribe what applications and services finally do with the data (parse, convert, store, make searchable, display to users, etc.).

    Terminology

    An Application Profile is a specification that reuses terms from one or more base standards, adding more specificity by identifying mandatory, recommended and optional elements to be used for a particular application, as well as recommendations for controlled vocabularies to be used.

    A Dataset is a collection of data, published or curated by a single source, and available for access or download in one or more formats. A Data Portal is a Web-based system that contains a data catalogue with descriptions of datasets and provides services enabling discovery and reuse of the datasets.

    Overview

    This Application Profile extends [[DCAT-AP-3]] by including

  • additional classes and properties;
  • additional recommendations on the use of classes and properties;
  • additional controlled vocabularies (documented in 9. Controlled Vocabularies to be used, along with the ones used in [[DCAT-AP-3]]).

    • These extensions are meant to provide a DCAT-AP-conformant representation of geospatial metadata, identified by defining RDF syntax mappings covering the union of the elements in the INSPIRE metadata schema [[INSPIRE-MD-REG]], [[INSPIRE-MD]] and the core profile of [[ISO-19115]], following the criteria illustrated in A. INSPIRE and ISO 19115 Mappings.

    The current specification does not change the set of geospatial metadata elements already covered in its previous version [[GeoDCAT-AP-20201223]], but rather it updates some of the corresponding mappings based on the new classes and properties included in [[DCAT-AP-3]], following the release of version 2 of the W3C Data Catalog (DCAT) Vocabulary [[vocab-dcat-3]], and aligns them with version 2.2.0 of the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]].

    Application profile diagram

    An overview of GeoDCAT-AP is shown by the UML diagram below. The UML diagram illustrates the specification described in this document. For readability purposes, the representation has been condensed as follows: The cardinalities and qualifications are included in the figure. This specification distinguishes between main entities, i.e. classes in the core of the application profile, supporting entities, i.e. classes used for representation of less crucial aspects of the application profile, and datatypes used for typing literal values.

    This document describes the usage of the following main entities for a correct usage of the Application Profile:
    | Agent | Catalogue | Catalogue Record | Catalogued Resource | Checksum | Data Service | Dataset | Dataset Series | Distribution | Kind | Licence Document | Location | Relationship |

    The main entities are supported by:
    | Activity | Address (Core Location) | Address (vCard) | Association | Attribution | Checksum Algorithm | Concept | Concept Scheme | Datatype | Dimension | Document | Email (vCard) | Entity | Frequency | Geometry | Identifier | Legal Resource | Linguistic system | Literal | Metric | Organisation | Period of time | Policy | Provenance Statement | Quality Measurement | Resource | Rights statement | Role | Standard |

    And supported by these datatypes:
    | Media Type | Media Type or Extent | Temporal Literal | Time instant | xsd:decimal | xsd:duration | xsd:hexBinary | xsd:nonNegativeInteger |

    Controlled Vocabularies

    Requirements for controlled vocabularies

    The following is a list of requirements that were identified for the controlled vocabularies to be recommended in this Application Profile.

    Controlled vocabularies SHOULD:

    These criteria do not intend to define a set of requirements for controlled vocabularies in general; they are only intended to be used for the selection of the controlled vocabularies that are proposed for this Application Profile.

    Expected usage of controlled vocabularies

    To increase the interoperability, the value spaces of properties can be further harmonised using shared controlled vocabularies. This kind of restriction may be subject to a varying interpretation on what the expected usage of a controlled vocabulary is. To ensure a common interpretation the following expectations are defined:

    The first two (and preferably also the others) SHOULD only be used for requirements that can be verified by a machine. If the validation can only be realised with the involvement of humans, then a less strong requirement (RECOMMMENDED or MAY) is used, even if the intention is to be very strict. This is to ensure that the provided SHACL representations correspond closely to all use cases possible. Stronger enforcements are left for implementations as they have control on actual data exchange.

    Controlled vocabularies to be used

    The table is organised per property and then per class. This is because mostly the used controlled vocabulary is connected with the property and not with the usage context in a class. However this is not mandatory, and it may happen (as it is the case for dct:type) that the same property uses a different controlled vocabulary per class. To disambiguate the usage multiple rows are created. In some cases controlled vocabulary usage is more complicated. For instance in the case of dct:spatial and dct:publisher the usage of the controlled vocabulary is dependent on the actual value used. The value space these properties encompass is very large and there is no universal EU controlled vocabulary at hand that covers the whole value space.

    The last column is a first assessment of the usage of the controlled vocabularies and is open for discussion.

    Compared with DCAT-AP, GeoDCAT-AP makes use of additional controlled vocabularies mandated by [[INSPIRE-MD-REG]], and operated by the INSPIRE Registry - with the only exceptions of the coordinate reference systems register maintained by OGC [[OGC-EPSG]].

    For two of these controlled vocabularies, namely the INSPIRE spatial data themes [[INSPIRE-THEMES]] and the ISO topic categories [[INSPIRE-TC]], the GeoDCAT-AP Working Group has defined a set of harmonised mappings to the EU Vocabularies Data Themes [[EUV-THEMES]], in order to facilitate the identification of the relevant theme in [[EUV-THEMES]] for geospatial metadata. The status of this work, along with links to a machine readable representation of the mappings, is documented on a dedicated page in Joinup [[?GeoDCAT-ACV]].

    Other controlled vocabularies

    In addition to the proposed common vocabularies in , which are mandatory to ensure minimal interoperability, implementers are encouraged to publish and to use further region or domain-specific vocabularies that are available online. While those may not be recognised by general implementations of the Application Profile, they may serve to increase interoperability across applications in the same region or domain. Examples are the full set of concepts in EuroVoc [[?EUV-EUROVOC]], the CERIF standard vocabularies [[?CERIF-VOCS]], the Dewey Decimal Classification [[?DDC]] and numerous other schemes.

    For geospatial metadata, the working group has identified the following additional vocabularies:

    Agent Roles

    GeoDCAT-AP supports the 11 agent roles defined in [[INSPIRE-MD-REG]] and [[ISO-19115]] by using two different but not mutually exclusive approaches.

    In the first approach, roles are mapped to specific properties. In particular, GeoDCAT-AP makes use of the relevant properties from [[DCAT-AP-3]] and [[DCTERMS]], which overall cover 4 of the relevant roles - namely, dcat:contactPoint, dct:creator, dct:publisher, and dct:rightsHolder (not supported in [[DCAT-AP-3]]). The remaining 7 are covered by the corresponding properties defined in the GeoDCAT-AP namespace - namely, geodcatap:custodian, geodcatap:distributor, geodcatap:originator, geodcatap:principalInvestigator, geodcatap:processor, geodcatap:resourceProvider, and geodcatap:user.

    It is important to note that, following [[INSPIRE-MD-REG]] and [[ISO-19115]], in GeoDCAT-AP all these agent roles can be specified on Catalogues, Catalogue Records, Datasets, and Data Services.

    The second and more general approach is based on [[PROV-O]], where agent roles are specified via a “qualified attribution” (prov:qualifiedAttribution). More precisely, the relevant Agent is specified via property prov:agent, whereas the role is specified with property dcat:hadRole, which takes as value a skos:Concept describing that role - as those included in the relevant code list operated by the INSPIRE Registry [[INSPIRE-RPR]]. .

    The [[PROV-O]]-based approach is meant to give data providers an extension mechanism to specify, in a harmonised way, any kind of role, and, possibly, to attach additional information to the role and the associated Agent. As such, it MAY be used in combination with or to complement the property-based approach, but it MUST NOT replace it. For instance, it can be used to specify roles not covered by the agent role properties used in GeoDCAT-AP, and/or to specify additional information that cannot be expressed via a property (as the period during which an Agent covered a given role).

    More details on these solutions are available in .

    Accessibility and Multilingual Aspects

    Accessibility in the context of this Application Profile is limited to information about the technical format of distributions of datasets. The properties dcat:mediaType and dct:format provide information that can be used to determine what software can be deployed to process the data. The accessibility of the data within the datasets needs to be taken care of by the software that processes the data and is outside of the scope of this Application Profile.

    Multilingual aspects related to this Application Profile concern all properties whose contents are expressed as strings (i.e. rdfs:Literal) with human-readable text. Wherever such properties are used, the string values are of one of two types:

    Wherever values of properties are expressed with either type of string, the property can be repeated with translations in the case of free text and with parallel versions in case of named entities. For free text, e.g. in the cases of titles, descriptions and keywords, the language tag is mandatory.

    Language tags to be used with rdfs:Literal are defined by [[BCP47]], which allows the use of the "t" extension for text transformations defined in [[RFC6497]] with the field "t0" [[CLDR]] indicating a machine translation.

    A language tag will look like: "en-t-es-t0-abcd", which conveys the information that the string is in English, translated from Spanish by machine translation using a tool named "abcd".

    For named entities, the language tag is optional and should only be provided if the parallel version of the name is strictly associated with a particular language. For example, the name ‘European Union’ has parallel versions in all official languages of the union, while a name like ‘W3C’ is not associated with a particular language and has no parallel versions.

    For linking to different language versions of associated web pages (e.g. landing pages) or documentation, a content negotiation [[CONNEG]] mechanism may be used whereby different content is served based on the Accept-Languages indicated by the browser. Using such a mechanism, the link to the page or document can resolve to different language versions of the page or document.

    All the occurrences of the property dct:language, which can be repeated if the metadata is provided in multiple languages, must have a URI as their object, not a literal string from the [[ISO-639]] code list.

    How multilingual information is handled in systems, for example in indexing and user interfaces, is outside of the scope of this Application Profile.

    High Value Datasets

    In light of the growing importance of data, the European Commission has adopted an implementing regulation focused on high-value datasets on 21 December 2022 [[HVD]]. The ambition of the High-Value Datasets implementing regulation (HVD IR) is to improve the availability, accessibility, quality and reuse of a selective set of core datasets from the public sector whose re-use is associated with important socio-economic benefits. To achieve this the HVD IR sets, among others, requirements on the metadata associated with the disclosed datasets.

    To foster a common approach on using DCAT-AP metadata to describe Datasets that are in scope of the HVD IR a dedicated DCAT-AP annex DCAT-AP HVD [[DCAT-AP-HVD]] is provided. The requirements expressed in DCAT-AP HVD are additional constraints and usages notes which can be directly applied to GeoDCAT-AP 3.0.0.

    Because GeoDCAT-AP is also applicable for datasets that are not within the scope of the HVD IR, the constraints of DCAT-AP HVD are not included in this specification. Implementers of the HVD IR should consult DCAT-AP HVD to check the specific requirements of the HVD IR and the adherence to them. However, since GeoDCAT-AP is mainly used as the DCAT view derived from the INSPIRE ISO metadata [[[#inspire-and-iso-19115-mappings]]], the implementation of the DCAT-AP HVD in the context of a GeoDCAT-AP mapping requires to implement additional mapping rules, specified in [[[#inspire-and-iso-19115-mappings]]].

    A clear mapping between HVD categories and INSPIRE data themes has been early defined by this community during the process of drafting the High-Value Datasets implementing regulation [[HVD]], as illustrated in the figure below:

    Mapping between HVD categories and INSPIRE data themes

    For this reason, the identification of HVD in the scope of INSPIRE is currently relying on this mapping. No additional generic requirements for tagging these datasets are provisioned, except in the case of Integrated Administration and Control System (IACS) agricultural datasets in the scope of the European Common Agricultural Policy (CAP), mainly represented by the Land Parcel Identification System (LPIS) and the Geospatial Aid application (GSAA) datasets.

    Despite IACS datasets are in the scope of either the Land cover, Land use, Cadastral parcels, Agricultural facilities and/or Area management zones INSPIRE themes, there is a need to further facilitate their discoverability among other datasets belonging to the Geospatial HVD category (See the Annex of the Implementing Regulation focused on high-value datasets on 21 December 2022 [[HVD]]). Additionally, a need to classify them as Reference parcels or Agricultural parcels as defined in Regulation (EU) No 1306/2013 of the European Parliament and of the Council [[AGRI-POLICY]] and of Regulation (EU) No 1307/2013 of the European Parliament and of the Council [[AGRI-POLICY-FARMERS]], respectively.

    To satisfy these needs, the "INSPIRE Technical guidelines on IACS spatial data sharing. Part 1 - Data discovery" [[IACS]] sets specific requirements and recommendations for describing IACS datasets through the INSPIRE infrastructure.

    The INSPIRE Maintenance and Implementation Group (MIG) is discussing potential additional requirements and recommendations for the provision of INSPIRE HVD datasets and their corresponding metadata (e.g. on metadata tagging) as part of the ongoing activities of its Ad-hoc Subgroup on the Alignment of INSPIRE and High-Value Datasets implementation (MIG Action 2.5) [[A2.5]]. This specification will be duly updated in case additional provisions enter into force in the future.

    Legal information

    The considerations for expressing legal information follow the guidelines and approach of DCAT-AP. Readers should consult the DCAT-AP section on legal information.

    The HVD IR [[HVD]] imposes additional quality requirements on legal information. An elaboration of these is found in the section legal information in DCAT-AP HVD.

    Implementers of mappings from INSPIRE ISO metadata should take these considerations into account to ensure that the legal information is shared correctly.

    Privacy and security considerations

    GeoDCAT-AP supports the attribution of data and metadata to various participants such as resource creators, publishers and other parties or agents, and as such defines terms that may be related to personal information. In addition, it also supports the association of rights and licenses with catalogued Resources and Distributions. These rights and licenses could potentially include or reference sensitive information such as user and asset identifiers as described in [[VOCAB-ODRL]].

    Implementations that produce, maintain, publish or consume such vocabulary terms must take steps to ensure security and privacy considerations are addressed at the application level.

    Conformance Test Results

    Following [[INSPIRE-MD-REG]] and [[ISO-19115]], GeoDCAT-AP supports the specification of test results to assess the degree of conformity of a resource (i.e., a Catalogue, a Dataset, a Data Service) with a given specification (e.g., a standard, a set of implementing rules, a set of data quality or interoperability criteria).

    For this purpose, GeoDCAT-AP makes use of two different but not mutually exclusive approaches. More precisely, property dct:conformsTo is used when the test result states that a resource is conformant with a given specification. The more general approach is based on [[PROV-O]], and it specifies conformance test results as a testing activity (prov:Activity) that generates a result (specified with property prov:generated), corresponding to one of the degrees of conformity defined in [[INSPIRE-MD-REG]], and available from the INSPIRE Registry [[INSPIRE-DoC]]. The specification against which the testing activity is carried out is specified via a “qualified association” (prov:qualifiedAssociation), linked to a “plan” (prov:hadPlan) derived from (prov:wasDerivedFrom) the specification itself.

    More details on these solutions are available in .

    Validation of GeoDCAT-AP

    Validation of a catalogue according to GeoDCAT-AP can be approached from different perspectives. One perspective is to consider GeoDCAT-AP as an extension to DCAT-AP and thus implement a two staged process: first validation against DCAT-AP and then additionally validate the GeoDCAT-AP specific constraints. Another perspective is to consider this specification as a standalone specification and validate all constraints at once. Besides these there are many other validation perspectives possible. For additional considirations on validation consult the section Validation in DCAT-AP.

    As there is yet not preferred perspective decided nor requested by the community, a similar to DCAT-AP SHACL artefact with all the constraints is provided. The shape is downloadable here.

    INSPIRE and ISO 19115 Mappings

    Objectives

    The objective of this work is to define an RDF syntax that can be used for the exchange of descriptions of spatial datasets, dataset series, and services among data portals. The RDF syntax should extend the DCAT Application Profile for data portals in Europe [[DCAT-AP-3]].

    Additionally, the following outcomes may be achieved, outside the context of this specification:

    Motivation and use cases

    The basic use case that GeoDCAT-AP intends to enable is a cross-domain data portal search for datasets, as documented in the DCAT-AP specification [[DCAT-AP-3]]. GeoDCAT-AP will make it easier to share descriptions of spatial datasets between spatial data portals and general data portals, and thus help increase public and cross-sector access to such high value datasets. The datasets could include:

    Datasets on the INSPIRE Geoportal

    The INSPIRE Geoportal aggregates metadata for over 100k datasets across Europe. It provides the means to search for spatial data sets and spatial data services, and subject to access restrictions, to view spatial data sets from the EU Member States within the framework of the INSPIRE Directive. The metadata stored on this portal is structured according to the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]]. In order to maximise visibility and re-use, spatial datasets could also be listed on general-purpose Open Data Portals, such as data.europa.eu, the official portal for European data.

    Datasets on national SDIs

    GeoDCAT-AP would facilitate the integration of SDIs operated by EU Member States with any data catalogue able to consume [[DCAT-AP-3]]-compliant metadata.

    General geospatial datasets

    The geospatial community shares a common background and makes consistent use of consolidated standards and technologies. In particular, as far as metadata are concerned, it is widespread to use standards like [[ISO-19115]] / [[ISO-19139]], for the representation and encoding of metadata, and OGC’s [[?CSW]] (Catalog Service for the Web) for accessing and querying metadata records. These standards are also those required in INSPIRE.

    An additional RDF syntax for INSPIRE and ISO 19115 metadata elements is beneficial, especially when other data portals support the [[DCAT-AP-3]] metadata elements only.

    Conversion rules to RDF syntax would allow Member States to maintain their collections of INSPIRE-relevant datasets following the INSPIRE Metadata Technical Guidelines [[INSPIRE-MD]], while at the same time publishing these collections on [[DCAT-AP-3]]-conformant data portals. A conversion to RDF syntax – using for example the GeoDCAT-AP XSLT script [[GeoDCAT-XSLT]] - allows additional metadata elements to be displayed on general-purposed data portals, provided that such data portals are capable of displaying additional metadata elements. Furthermore, data portals are frequently complemented by a triple store, making the full set of GeoDCAT-AP metadata queryable through a SPARQL endpoint [[SPARQL11-QUERY]].

    Supported tooling

    To support the transformation from INSPIRE metadata to GeoDCAT-AP compliant metadata, a reference XSLT transformation was developed, and is being maintained. This transformation has been updated to transform data to be compliant with GeoDCAT-AP 3.0.0. The reference XSLT can be found in a GitHub repository. The XSLT can be run directly on the output of a CSW or on single metadata records, by using any of the programming languages supporting XSLT conversion.

    The reference XSLT is not meant to be used in production directly. It serves as a reference which needs to be adjusted according to the specific needs and practice of the individual metadata publishers, as the practice is currently not coherent across publishers in certain aspects. These aspects include:

    • Identifiers of datasets, dataset series, distributions and data services, and their persistence for HVD. A method for establishing the identifiers needs to be implemented.
    • Licenses for HVD in cases where they are identified by IRIs, but do not use the EU Vocabularies Licence NAL directly. See [[DCAT-AP-HVD]]. A mapping needs to be implemented.
    • Representation of Data Services and their connection to Datasets due to the INSPIRE metadata simplification. Identification of Data Services and a method for their connection to Datasets needs to be implemented.
    • Mapping of INSPIRE themes to EU Vocabularies Data themes for cases where the Data themes are not included in the source metadata.

    Methodology and summary of results

    Methodologically, the development of GeoDCAT-AP implies three main interrelated tasks:

    1. Definition of alignment criteria and requirements.

    2. Identification of the metadata elements to be covered by GeoDCAT-AP.

    3. Definition of alignments for the metadata elements to be covered by GeoDCAT-AP.

    These tasks and their results are described in the following sections.

    Alignment criteria and requirements

    The overall objectives of GeoDCAT-AP are:

    1. Provide a [[DCAT-AP-3]]-conformant representation of geospatial metadata.

    2. Provide an as much as possible comprehensive RDF-based representation of geospatial metadata, based on widely used vocabularies, trying, at the same time, to avoid semantic loss and to promote cross-domain re-use.

    3. Ensure backward compatibiliy with previous versions of GeoDCAT-AP.

    The first two goals, having a different scope and applying to different use cases (see ), are reflected in the two mapping profiles of GeoDCAT-AP, core and extended, described in .

    Note that point (1) implies that:

    • GeoDCAT-AP must include, at least, all the mandatory [[DCAT-AP-3]] elements.

    • Vocabularies different from [[DCAT-AP-3]] can be used only for those geospatial metadata elements not supported in [[DCAT-AP-3]].

    Another key criterion was to base as much as possible the defined alignments on existing practices, in particular those contributed by the GeoDCAT-AP WG. The objective was to build upon experiences having already addressed issues in scope of GeoDCAT-AP, and to avoid a negative impact on existing implementations.

    Finally, as already mentioned in , whenever no suitable candidates were available in existing vocabularies to represent geospatial metadata elements, the possibility of defining new terms was not excluded. However, this option needed to be carefully assessed, and discarded whenever it might have led to a specification that was conflicting with standards under preparation.

    As it will be explained in , no new terms have been defined in the current version of GeoDCAT-AP.

    Metadata elements to be covered by GeoDCAT-AP

    The general criterion used for this task was that GeoDCAT-AP would ideally cover all the metadata elements of the core of [[ISO-19115]] and those defined in INSPIRE, with the requirement that only optional elements MAY be excluded.

    Based on this, the current version of GeoDCAT-AP covers the following set of metadata elements:

    • All the metadata elements in the core of [[ISO-19115]].

    • All the metadata elements defined in INSPIRE, with the exclusion of those not common to all the INSPIRE spatial data themes.

    More precisely, the supported INSPIRE metadata elements include:

    • The set of metadata elements defined in the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]].

    • The set of metadata elements defined in the INSPIRE Data and Services Regulation (Article 13: “Metadata required for Interoperability”) [[INSPIRE-SDSS-REG]]. These elements are also listed in Appendix C.3 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]].

    • The set of metadata elements recommended as common to most of the INSPIRE spatial data themes in the INSPIRE Data Specifications Technical Guidelines, and listed in the first table included in Appendix C.7 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]]. These elements are the following ones:

      • Maintenance information.

      • Conceptual and domain consistency (Data quality – Logical consistency).

    The full list of metadata elements covered by the current version of GeoDCAT-AP is available in to this document.

    The metadata elements not supported in the current version of GeoDCAT-AP are those recommended only for specific INSPIRE spatial data themes in the INSPIRE Data Specifications Technical Guidelines, and listed in Appendix C.7 to the INSPIRE Metadata Technical Guidelines (version 2.2.0) [[INSPIRE-MD]].

    These elements have been excluded in the current version of GeoDCAT-AP for the following reasons:

    • The priority was to support all those elements relevant to any dataset.

    • These elements are all optional.

    Support to these metadata elements might be provided in future versions of GeoDCAT-AP.

    Alignments defined in GeoDCAT-AP

    The alignments defined in the current version of GeoDCAT-AP are the result of an iterative revision process of [[GeoDCAT-AP-20201223]], following the criteria illustrated in the previous sections and the review of the GeoDCAT-AP WG. Alignments for [[ISO-19115-1]] have not been defined. contains an overview of the most important changes with respect to [[ISO-19115]].

    The work started with the review of [[DCAT-AP-3]], [[VOCAB-DCAT-3]], and [[INSPIRE-MD]], with the purpose of identifying possible disalignments of the mappings defined in [[GeoDCAT-AP]], as well as possible gaps in [[DCAT-AP-3]] and [[VOCAB-DCAT-3]], which may require the use of different vocabularies or the definition of new classes and/or properties in the GeoDCAT-AP namespace. In all these cases, backward compatibility with [[GeoDCAT-AP-20201223]] has been taken into account when implementing revisions.

    Finally, the GeoDCAT-AP WG has worked in close coordination with the DCAT-AP WG, in order to ensure mutual compliance of the proposed solutions.

    The results of this work, reflected in the current version of GeoDCAT-AP, can be summarised as follows:

    • Compliance with [[DCAT-AP-3]] is ensured: The geospatial metadata elements covered by the defined mappings include all those that in [[DCAT-AP-3]] are mandatory, plus a subset of those that are recommended and optional.

    • GeoDCAT-AP offers alignments for all the metadata elements illustrated in , by using existing vocabularies, and without defining new terms.

    The majority of the alignments defined in GeoDCAT-AP provide a complete representation of the corresponding geospatial metadata elements, but some metadata elements have open issues:

    • Partial mappings: For some metadata elements, only a partial mapping is available. This concerns data quality and maintenance information, for which only the mandatory components have been mapped (for more details, see and , respectively). This decision was taken because existing vocabularies did not offer the ability to represent all the components of these metadata elements.

    The details of the alignments defined in GeoDCAT-AP are illustrated in the following section.

    RDF syntax bindings for INSPIRE and ISO 19115 metadata elements

    The following sections provide the list of the bindings defined in GeoDCAT-AP for the RDF representation of INSPIRE metadata and the core of [[ISO-19115]].

    For detailed usage notes and examples of each of the metadata elements covered by GeoDCAT-AP, we refer the reader to (the relevant section is specified in the “comments” column of the mapping table).

    There are three basic situations for each binding defined below:

    1. Binding directly supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Core
    2. Binding partially supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Core and supplemented by a binding in GeoDCAT-AP Extended
    3. Binding not supported by [[DCAT-AP-3]]: binding is defined as part of GeoDCAT-AP Extended

    Overview of bindings for GeoDCAT-AP Core

    This section provides an overview of GeoDCAT-AP Core. This includes bindings for metadata elements of the INSPIRE metadata, metadata elements in the core of [[ISO-19115]] for which DCAT-AP provides an RDF syntax binding, and metadata elements supporting common practice, such as . Those metadata elements for which [[DCAT-AP-3]] does not provide a binding are part of the GeoDCAT-AP Extended mapping profile described in .

    GeoDCAT-AP Core is meant to enable the harvesting and re-use of spatial metadata records through [[DCAT-AP-3]]-conformant applications and services, including data portals and APIs. The alignments for INSPIRE and [[ISO-19115]] metadata elements that are not included in GeoDCAT-AP Core are defined in GeoDCAT-AP Extended, see .

    In the following table, the starred elements (*) are used to indicate the corresponding metadata element in the core of [[ISO-19115]]. For each element, it is indicated whether the element is mandatory (M), optional (O), conditional (C), or recommended (R) in either specification.

    Overview of bindings for GeoDCAT-AP Extended

    This section provides an overview of the RDF syntax bindings in GeoDCAT-AP Extended. This GeoDCAT-AP mapping profile covers elements defined in INSPIRE and the core of [[ISO-19115]], for which [[DCAT-AP-3]] does not provide a fully suitable syntax binding. GeoDCAT-AP Extended therefore complements GeoDCAT-AP Core with a more complete representation beyond [[DCAT-AP-3]].

    The following table contains the defined RDF syntax binding for INSPIRE metadata. In the table below, the starred elements (*) are used to indicate the corresponding metadata element in the core of [[ISO-19115]]. For each metadata element, it is indicated whether the element is mandatory (M), optional (O), conditional (C), or recommended (R) in either specification.

    Please note that some metadata elements have an RDF syntax binding in both the GeoDCAT-AP Core and Extended mapping profile. These elements fall in one of the following two categories:

    1. Partial coverage by a [[DCAT-AP-3]] binding: This concerns conformity (only degree of conformity equal to “conformant” is supported) and responsible organisation (only responsible party roles creator, publisher, and point of contact are supported).

    2. Subsumption by a GeoDCAT-AP RDF binding: ISO metadata elements available in GeoDCAT-AP Core, but for which only a many-to-one mapping is supported in [[DCAT-AP-3]].

    In order to preserve the original semantics, the extended mapping profile of GeoDCAT-AP defines additional alignments to those included in GeoDCAT-AP Core. The two sets of alignments are not mutually exclusive, and can coexist without creating conflicts.

    Overview of metadata elements covered by GeoDCAT-AP

    The following table provides an overview of the metadata elements in the INSPIRE metadata schema and in the core of [[ISO-19115]], and the available mappings in [[DCAT-AP-3]] and GeoDCAT-AP. Columns titled with “obligation” specify whether the corresponding metadata elements are mandatory (M), conditional (C), and optional (O) (where “conditional” means “mandatory under given conditions”).

    Note that the mappings covered by [[DCAT-AP-3]] correspond to those defined in GeoDCAT-AP core, whereas those covered only by GeoDCAT-AP correspond to those defined in the GeoDCAT-AP extended.

    This binding may also include the specification of the language by using attribute @xml:lang [[XML]]. The language to be specified is the one indicated by element metadata language, mapped to the language identifiers defined by IETF BCP 47 [[BCP47]].

    Resource abstract - *Abstract describing the dataset

    The content of the elements ‘resource abstract’ can be represented in RDF as a plain literal, and by using property dct:description.

    This binding may also include the specification of the language by using attribute @xml:lang [[XML]]. The language to be specified is the one indicated by element metadata language, mapped to the language identifiers defined by IETF BCP 47 [[BCP47]].

    Resource type - *not in ISO 19115 core

    [[VOCAB-DCAT-3]] and [[DCAT-AP-3]] provide specific classes that can be used to represent the INSPIRE notions of dataset, dataset series, and service, namely, dcat:Dataset, dcat:DatasetSeries, and dcat:DataService.

    In order to explicitly indicate the correspondence with the relevant INSPIRE resource types, following the work on aligning INSPIRE Metadata and Dublin Core [[?INSPIRE-DC]], in the extended mapping profile of GeoDCAT-AP they will be denoted by using the resource type code list operated by the INSPIRE Registry [[INSPIRE-RT]], and by using geodcatap:resourceType. More precisely, the following URIs SHOULD be used to denote, respectively, dataset, series, and services:

    Additionally, the spatial data service type can be specified by using geodcatap:serviceType with the corresponding code lists operated by the INSPIRE Registry [[INSPIRE-SDST]].

    Resource locator - *On-line resource

    In INSPIRE, this element, quoting, defines the link(s) to the resource and/or the link to additional information about the resource. [[VOCAB-DCAT-3]] has a property, namely, dcat:landingPage, having exactly the same purpose.

    [[ISO-19115]] offers however the ability to specify the “type” of resource locator by using a specific code list (CI_OnlineFunctionCode), described in the following table:

    ISO 19115 – CI_OnlineFunctionCode Description
    download online instructions for transferring data from one storage device or system to another
    information online information about the resource
    offlineAccess online instructions for requesting the resource from the provider
    order online order process for obtaining the resource
    search online search interface for seeking out information about the resource

    Based on this, the mappings of element “resource locator” for data sets and data set series will vary depending on the function code (when available), based on the following table.

    ISO 19115 – CI_OnlineFunctionCode Property Domain Range
    (not provided) dcat:landingPage dcat:Dataset foaf:Document
    download dcat:accessURL dcat:Distribution rdfs:Resource
    Information foaf:page dcat:Dataset foaf:Document
    offlineAccess dcat:accessURL dcat:Distribution rdfs:Resource
    order dcat:accessURL dcat:Distribution rdfs:Resource
    search foaf:page dcat:Dataset foaf:Document

    However, whenever the URL points to a service endpoint, the resource locator SHOULD be always mapped to property dcat:accessURL, and complemented by additional two properties, namely, dcat:endpointURL and dcat:endpointDescription.

    More precisely, if the URL is recognised as pointing to a capabilities document, the URL is mapped to property dcat:endpointDescription, whereas property dcat:endpointURL will take as value the URL without it query string component.

    Properties dcat:endpointURL and dcat:endpointDescription will have as domain class dcat:DataService, linked to the dataset distribution via property dcat:accessService.

    Finally, whenever it is possible to recognise the service protocol, this information will be specified by property geodcatap:serviceProtocol, taking as value the URI of the relevant specification from the INSPIRE Registry's code list for protocol values [[INSPIRE-PV]].

    As far as services are concerned, the resource locator SHOULD be mapped to properties dcat:endpointURL, dcat:endpointDescription, and dct:conformsTo, as described above.

    Unique resource identifier - *not in ISO 19115 core

    In INSPIRE, this element is meant to uniquely identify a resource (dataset, series or service), and it is mandatory for datasets and series. It is specified by (a) a mandatory character string code and by (b) an optional character string namespace.

    Based on [[DCAT-AP-3]], unique resource identifiers are mapped to dct:identifier (see ). The actual value is obtained by the concatenation of the values of the namespace (if specified) and of the code in the original metadata record.

    If the unique resource identifier is specified with or can be encoded as an HTTP URI, it can be used as the URI of the resource (see ).

    Coupled resource - *not in ISO 19115 core

    This element is used to link a service to the target datasets or dataset series.

    Following [[VOCAB-DCAT-3]] and [DCAT-AP-3], this relationship is specified by using property dcat:servesDataset.

    The target dataset or series SHOULD be preferably referred to by using its unique resource identifier, as in .

    Resource language and metadata language - *Dataset language and Metadata language

    In INSPIRE metadata, metadata and resource languages (which may be different) are specified by using the three-letter language codes defined in [[?ISO-639-2]].

    Based on [[DCAT-AP-3]], both elements are specified with property dct:language, with the URI of the relevant language available from the relevant register operated by the EU Publications Office [[EUV-LANG]].

    assumes that the metadata language is Dutch, and the resource language is German.

    The metadata language can be also used to specify the language of textual elements of resource metadata by using the @xml:lang attribute [[XML]].

    Since @xml:lang takes as value language identifiers defined by IETF BCP 47 [[BCP47]], a mapping from the actual value of the metadata language is needed.

    Topic category, originating controlled vocabulary, and keyword value - *Dataset topic category

    In INSPIRE, these two elements have specific purposes. Quoting from the INSPIRE Metadata Regulation [[?INSPIRE-MD-REG]] (§2.1 and §3.1, respectively):

    • The topic category is a high-level classification scheme to assist in the grouping and topic-based search of available spatial data resources.

    • The keyword value is a commonly used word, formalised word or phrase used to describe the subject. While the topic category is too coarse for detailed queries, keywords help narrowing a full text search and they allow for structured keyword search.

    Moreover, two types of keywords are allowed:

    • free keywords;

    • keywords taken from a controlled vocabulary.

    Finally, topic categories apply only to datasets and dataset series.

    Topic category and keyword in datasets and dataset series

    As far as dataset metadata are concerned, in both [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], a distinction is made only between free keywords and keywords from controlled vocabularies, associated with a URI. For the former, dcat:keyword is used, whereas for the latter dcat:theme (which is a sub-property of dct:subject). Since the INSPIRE Registry operates URI registers for topic categories and INSPIRE spatial data themes, and in order to keep the distinction existing in INSPIRE between topic categories and keywords, the mapping is as follows:

    Following [[DCAT-AP-3]] recommendations, keywords from controlled vocabularies SHOULD be preferably specified with dereferenceable HTTP URIs. In such a case, the information concerning the originating controlled vocabulary can be omitted.

    When keywords cannot be specified with HTTP URIs, they SHOULD be typed as a skos:Concept associated with a skos:ConceptScheme (used to type the originating controlled vocabulary), and annotated with the textual content and reference date(s) in the relevant INSPIRE metadata elements.

    The representation of the information concerning the controlled vocabulary is illustrated in the following table.

    Metadata Element Proposed mapping
    Originating controlled vocabulary Title skos:ConceptScheme dct:title
    Reference date creation dct:created
    last revision dct:modified
    publication dct:issued

    For conformance with [[DCAT-AP-3]], GeoDCAT-AP records MUST also include keywords from the EU Vocabularies Data Theme Named Authority List [[EUV-THEMES]].

    In order to ensure consistency, the relevant EU Vocabularies Data Theme keywords SHOULD be selected based on mappings with the controlled vocabularies used in INSPIRE / ISO 19115 metadata.

    Keyword in services

    As far as service metadata are concerned, keywords can classify either a service or the datasets / series operated by the service itself. For the latter, INSPIRE Metadata Regulation requires using at least one of the keywords from the ISO 19119 code list of spatial data service categories.

    In order to keep the distinction between these two types of keywords, the adopted solution is as follows:

    Spatial data service type - *not in ISO 19115 core

    See on resource type.

    Geographic bounding box - *Geographic location of the dataset (by 4 coordinates or by geographic identifier)

    In the core of [[ISO-19115]], spatial coverage can be specified either with a bounding box (a geometry) or a geographic identifier. INSPIRE is more restrictive, in that it requires using a bounding box

    Based on that, GeoDCAT-AP specified spatial coverage as illustrated in the following sections.

    Bounding box

    As a general rule, when the area corresponding to the spatial coverage is denoted by a geometry, as in INSPIRE, [[DCAT-AP-3]] recommends the use of the Core Location Vocabulary [[LOCN]], where this is done by using property locn:geometry, having as range a geometry specified as

    • a URI - e.g., by using the geo URI scheme (IET RFC-5870) [[?RFC5870]], or a geohash URI [[?GEOHASH]], [[?GEOHASH-36]];

    • a syntax encoding scheme - e.g., geohashes [[?GEOHASH]], [[?GEOHASH-36]], WKT [[?ISO-19125-1]], GML [[?GML]], KML [[?KML]], GeoJSON [[?RFC7946]]; or

    • a semantic representation - using vocabularies like W3C Lat/long [[?W3C-BASIC-GEO]] or schema.org [[?SCHEMA-ORG]].

    However, in case the geometry is a bounding box or a centroid, properties dcat:bbox and dcat:centroid, respectively, SHOULD be used instead of locn:geometry.

    It is worth noting that currently there is no agreement on a preferred format to be used in RDF for the representation of geometries. In GeoDCAT-AP, geometries can be provided in any, and possibly multiple, encodings, but at least one of the following must be made available: WKT or GML. An additional requirement concerns the coordinate reference system (CRS) used, which may vary on a country or territory basis. The CRS must be specified in the GML or WKT encoding as required by GeoSPARQL [[GeoSPARQL11]]. Geometries shall be interpreted using the axis order defined in the spatial reference system used. For example, for CRS84 the axis order is longitude / latitude, whereas for WGS84 the axis order is latitude / longitude. Summarising:

    • Geometries MAY be provided in multiple encodings, but at least one of the following MUST be made available: GML and WKT.

    • For GML and WKT, the CRS MUST be specified as defined in GeoSPARQL [[GeoSPARQL11]].

    As geometries may be provided in multiple encodings, the corresponding datatype SHOULD be always specified to ensure that the geometry literal is correctly interpreted.

    For GML and WKT, the [[GeoSPARQL11]] datatypes gsp:gmlLiteral and gsp:wktLiteral, respectively, MUST be used.

    For GeoJSON [[?RFC7946]], datatype gsp:geoJSONLiteral, defined in GeoSPARQL, version 1.1 [[?GeoSPARQL11]], SHOULD be used.

    For the other geometry encodings, no datatype is currently available. Therefore, their interoperability is not ensured when metadata records are shared or harvested across catalogues.

    Geographic identifier

    [[ISO-19115]] core also allows specifying the geographic location using a geographic identifier. Following [[DCAT-AP-3]], for this, it is RECOMMENDED to use an HTTP URI from one of the following registers / gazetteers:

    • The Named Authority Lists operated by the Metadata Registry of the EU Publications office concerning continents [[EUV-CONT]], countries [[EUV-COUNTRIES]], and places [[EUV-PLACES]].

    If none of the above provides the relevant geographic identifiers, Geonames [[?GEONAMES]] SHOULD be used.

    If an HTTP URI is not available, the geographic identifier MUST be expressed with skos:prefLabel, and the reference to the originating controlled vocabulary (if any) MUST be specified with skos:inScheme. The controlled vocabulary will be described by a name (dct:title) and a last modified data (dct:modified).

    As far as geographic identifiers are concerned, following [[DCAT-AP-3]], GeoDCAT-AP does not prevent the use other vocabularies in addition to the recommended ones. The vocabularies identified by the GeoDCAT-AP WG are listed in .

    Temporal reference and metadata date –*Additional extent information for the dataset (vertical and temporal) and *Metadata date stamp

    Temporal reference is a composite element consisting of the following possible child elements:

    • temporal extent (temporal coverage);

    • date of publication, last revision, and/or creation.

    Based on [[DCAT-AP-3]], temporal extent is mapped to dct:temporal, having as range dct:PeriodOfTime. The time instant or interval is specified by using properties dcat:startDate and dcat:endDate, respectively.

    By contrast, date of publication, last revision, and creation are mapped, respectively, to dct:issued, dct:modified (both core and extended GeoDCAT-AP mapping profiles), and dct:created (only for the extended mapping profile of GeoDCAT-AP).

    [[DCAT-AP-3]] does not have a property equivalent to the INSPIRE metadata element metadata date. In INSPIRE, this element is defined as follows (see [[INSPIRE-MD-REG]], Part B, §10.2):

    The date which specifies when the metadata record was created or updated.

    Due to this ambiguity, the defined mapping for this element is dct:modified.

    Lineage - *Lineage

    Following [[DCAT-AP-3]], this element is mapped to property dct:provenance.

    Since the range of dct:provenance is not a literal, but class dct:ProvenanceStatement, the free-text content of element “lineage” can be expressed by using dct:description.

    Spatial resolution – Spatial resolution of the dataset

    [[VOCAB-DCAT-3]] and [[DCAT-AP-3]] provide property dcat:spatialResolutionInMeters, to specify spatial resolution as distance in metres. Morever, [[VOCAB-DCAT-3]] and [[?SDW-BP]] recommend the use of [[VOCAB-DQV]] to specify other types of spatial resolution, via property dqv:hasQualityMeasurement.

    Based on this, GeoDCAT-AP specifies spatial resolution as follows:

    • Property dcat:spatialResolutionInMeters is used for spatial resolution when it is expressed as distance in metres.
    • Property dqv:hasQualityMeasurement is used for all types of spatial resolution. In such a case, the type of spatial resolution is specified by using property dqv:isMeasurementOf, which takes as value the relevant instance of class dqv:Metric defined in GeoDCAT-AP for this purpose (see Instances of Metric).
    • Property geodcatap:spatialResolutionAsText is used when spatial resolution is specified as free-text.

    The core mapping profile of GeoDCAT-AP, following [[DCAT-AP-3]], supports only the use property dcat:spatialResolutionInMeters, and, therefore, the other types of spatial resolution are left unmapped.

    Conformity and data quality - *not in ISO 19115 core

    In [[ISO-19115]], conformance and quality information is encoded as a quality report containing the result of a test (an evaluation) of a given quality measure, according to an evaluation method, with either a quantitative result (a metric) or a conformance result (pass or fail) as most important outcome.

    The current version of GeoDCAT-AP only defines a syntax binding for conformity and not for data quality in general, making use of property dct:conformsTo and the W3C Provenance Ontology (PROV-O) [[PROV-O]], as explained in the following paragraphs.

    [[DCAT-AP-3]] provides a single candidate, dct:conformsTo, which however can be used to map only a conformity of degree ‘conformant’. This is suitable for the core mapping profile of GeoDCAT-AP.

    Considering how conformity must be expressed in extended mapping profile of GeoDCAT-AP (see [[INSPIRE-MD-REG]], Part B, §7), possible candidates are the W3C Evaluation and Report Language (EARL) [[?EARL10]] and the W3C Provenance Ontology (PROV-O) [[PROV-O]]. The latter candidate was chosen by the GeoDCAT-AP Working Group, since it would enable wider re-use with respect to the EARL vocabulary, which is more specific, and its use is limited.

    [[PROV-O]] allows encoding conformity as a test activity (prov:Activity) that generated a result specified with property prov:generated, corresponding to the degree of conformity, for which the INSPIRE Registry maintains a URI set [[INSPIRE-DoC]]. The specification against which the conformance is asserted is specified via a qualified association (prov:qualifiedAssociation) with a test plan (a prov:Plan) in turn derived from a standard (dct:Standard, also prov:Entity). These associations are made via a property chain: prov:qualifiedAssociation, prov:hadPlan, and prov:wasDerivedFrom.

    This pattern is illustrated in the following table.

    Metadata element Proposed mapping
    Conformity Specification (M) Title prov:wasUsedBy (range prov:Activity) prov:qualifiedAssociation (range prov:Assocation) > prov:hadPlan (range prov:Plan) > prov:wasDerivedFrom (range: prov:Entity, dct:Standard) dct:title
    Reference date creation dct:created
    last revision dct:modified
    publication dct:issued
    Degree (M) prov:generated (range prov:Entity) dct:type (range [[INSPIRE-DoC]])
    dct:description

    In order to grant interoperability with [[DCAT-AP-3]], when conformity is of degree “conformant”, the proposal is to use both [[PROV-O]] and dct:conformsTo for GeoDCAT-AP Extended.

    Conditions for access and use and limitations on public access – Use limitation and access / other constraints

    In [[DCAT-AP-3]], licensing information is specified on (a) data catalogues (services) and on (b) the distribution(s) of a dataset, and not on the dataset itself. The principle is that different dataset distributions may be associated with different licensing terms. Moreover, [[DCAT-AP-3]] recommends the use of dct:accessRights for specifying access conditions. Both licenses and access rights should be indicated by their corresponding URIs.

    Based on this, GeoDCAT-AP specifies use and access limitations by using, respectively, dct:license and dct:accessRights whenever the value is available as a URI. Otherwise, since the range of these properties is not a literal, but, respectively, classes dct:LicenseDocument and dct:RightsStatement, the free-text content of the corresponding ISO 19115 / INSPIRE metadata elements can be expressed using dct:description on the dct:RightsStatement instance, connected using the dct:rights property.

    Responsible party and metadata point of contact - *Dataset responsible party and *Metadata point of contact

    [[DCAT-AP-3]] supports properties to denote the publisher, the creator, and the contact point for a dataset.

    By contrast, [[ISO-19115]] and [[INSPIRE-MD-REG]] support 11 possible relationships between a resource (a dataset, a dataset series, a service) and an agent (organisation), plus one for metadata. However, for only some of them suitable candidates exist from widely used vocabularies (in particular, DCMI Metadata Terms [[DCTERMS]]).

    In order to fill this gap, specific properties have been defined in the GeoDCAT-AP namespace to complement those available in [[DCAT-AP-3]] and [[DCTERMS]].

    The following table lists the mappings between responsible party roles and the corresponding properties used in GeoDCAT-AP.

    [[ISO-19115]] [[INSPIRE-MD-REG]] Description Proposed RDF mapping
    Resource provider Part B, §6.1 Party that supplies the resource. geodcatap:resourceProvider
    Custodian Part B, §6.2 Party that accepts accountability and responsibility for the data and ensures appropriate care and maintenance of the resource. geodcatap:custodian
    Owner Part B, §6.3 Party that owns the resource. dct:rightsHolder
    User Part B, §6.4 Party who uses the resource. geodcatap:user
    Distributor Part B, §6.5 Party who distributes the resource geodcatap:distributor
    Originator Part B, §6.6 Party who created the resource. geodcatap:originator
    Point of contact Part B, §6.7 Party who can be contacted for acquiring knowledge about or acquisition of the resource. dcat:contactPoint
    Principal investigator Part B, §6.8 Key party responsible for gathering information and conducting research geodcatap:principalInvestigator
    Processor Part B, §6.9 Party who has processed the data in a manner such that the resource has been modified. geodcatap:processor
    Publisher Part B, §6.10 Party who published the resource dct:publisher
    Author Part B, §6.11 Party who authored the resource. dct:creator

    The extended mapping profile of GeoDCAT-AP also supports the use of the W3C PROV ontology [[PROV-O]] and [[VOCAB-DCAT-3]] to specify the relationship between the resource and the responsible organisation. The FOAF Vocabulary [[FOAF]] is used to specify the contact information concerning the responsible party. Finally, the responsible party role will be specified by using dcat:hadRole, and using the relevant code list values from the INSPIRE Registry – reference register [[INSPIRE-RPR]]:

    http://inspire.ec.europa.eu/metadata-codelist/ResponsiblePartyRole

    These mappings are illustrated in the following table.

    Metadata element Proposed mapping
    Responsible party Responsible party Organisation name prov:qualifiedAttribution (range prov:Attribution) prov:agent (range prov:Agent, foaf:Agent) foaf:name
    Contact email address foaf:mbox
    Responsible party role dcat:hadRole (range dcat:Role)

    It is important to note that the [[PROV-O]]-based mappings are semantically equivalent to the property-based ones illustrated earlier in this section. Their use is therefore only accessory, and functional to possible requirements from the data provider side.

    For these reasons, the GeoDCAT-AP overall approach is as follows:

    • Responsible parties and their roles MUST be represented by the corresponding properties, based on an agreed definition of 1-to-1 mappings.
    • The property-based representation MAY be complemented with the [[PROV-O]]-based approach.

    As mentioned earlier, the latter option is supported only in the extended mapping profile of GeoDCAT-AP.

    *Metadata file identifier

    This element identifies a metadata record.

    Metadata file identifiers are mapped to dct:identifier.

    If the metadata file identifier is or can be encoded as an HTTP URI, it can also be used as the URI of the catalogue record (see ).

    *Metadata standard name, *Metadata standard version

    Following [[DCAT-AP-3]], GeoDCAT-AP uses dct:conformsTo to specify the metadata standard, and properties dct:title and owl:versionInfo are used to specify the standard name and version, respectively.

    This pattern is illustrated in the following table.

    Metadata element Proposed mapping
    Metadata standard Metadata standard name dct:conformsTo (range dct:Standard) dct:title
    Metadata standard version owl:versionInfo

    shows a GeoDCAT-AP metadata record obtained from one conformant with [[ISO-19115]].

    To represent the standard name and version of the source ISO record, the GeoDCAT-AP metadata record must be extended as in .

    *Metadata characterset

    Since in RDF serializations always use UTF-8, the metadata characterset is not reflected in the GeoDCAT-AP.

    Metadata point of contact - *Metadata point of contact

    See .

    Metadata date - *Metadata date stamp

    See .

    Metadata language - *Metadata language

    See .

    Coordinate reference systems and Temporal reference systems – *Reference System

    In GeoDCAT-AP, these elements are mapped to property geodcatap:referenceSystem. Moreover, in order to indicate which type of a reference system the object of geodcatap:referenceSystem denotes, an additional statement with predicate dct:type is added, with a code list value defining the notion of (spatial / temporal) reference system, taken from the glossary operated by the INSPIRE Registry [[INSPIRE-GLOSSARY]].

    More precisely, the following URIs SHOULD be used to denote, respectively, spatial and temporal reference systems:

    The reference system identifier SHOULD be preferably represented with an HTTP URI. In particular, spatial reference systems should be specified by using the corresponding URIs from the “EPSG coordinate reference systems” register operated by the Open Geospatial Consortium [[OGC-EPSG]].

    In this register, the URI prefix for coordinate reference systems is the following one:

    http://www.opengis.net/def/crs/EPSG/0/

    followed by the number identifying the coordinate reference system in the EPSG register. For instance, the following URI

    http://www.opengis.net/def/crs/EPSG/0/4258

    identifies coordinate reference system EPSG 4258, corresponding to ETRS89 (European Terrestrial Reference System 1989).

    In case the reference system is not specified as an HTTP URI, the mapping covers also other information included in the source metadata - as the identifier (dct:identifier), name (dct:title), and version (owl:versionInfo), plus a reference to the relevant register, if available (skos:inScheme). If a reference register is available, the reference system is implicitly also a skos:Concept, and its name can be specified by using skos:prefLabel.

    If not represented with an HTTP URI, the reference system identifier MUST be mapped to dct:identifier, as in .

    Character encoding - *Dataset character set and *Metadata character set

    In [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], the specification of the character encoding of a dataset and the character encoding of a metadata record is not explicitly supported. Moreover, since GeoDCAT-AP is an RDF-based specification, the metadata represented using GeoDCAT-AP are always in the UTF-8 encoding.

    According to [[?RFC4288]], the character set can be part of the media type specification, but only for type “text”. By contrast, in INSPIRE the character set can be specified also for other media types.

    The W3C Content vocabulary [[Content-in-RDF10]] provides a possibly suitable candidate, namely, property cnt:characterEncoding, taking as value the character set names in the IANA register [[IANA-CHARSETS]]. GeoDCAT-AP uses this property.

    Character encoding in [[ISO-19115]] metadata is specified with a code list that can be mapped to the corresponding codes in [[IANA-CHARSETS]], as shown in the following table (entries with 1-to-many mappings are in italic).

    Encoding - *Distribution format

    In both [[VOCAB-DCAT-3]] and [[DCAT-AP-3]], this information is specified for the distribution(s) of a dataset, and not for the dataset itself.

    Two properties are available:

    • dcat:mediaType: to be used when the format corresponds to one of the media types registered by IANA [[IANA-MEDIA-TYPES]].

    • dct:format: to be used in all the other cases, to be used with file type register operated by the Publications Office of the EU [[EUV-FT]].

    The same approach is used in GeoDCAT-AP for ISO 19115 / INSPIRE metadata.

    Spatial representation type – *Spatial representation type

    In [[DCAT-AP-3]], no equivalent term is provided.

    In [[ISO-19115]], element “Spatial representation type” is meant mainly to describe the “method used to represent geographic information in the dataset”, by using a code list (see the table below).

    The ADMS vocabulary [[VOCAB-ADMS]] includes a property, namely, adms:representationTechnique that could be used for this purpose. It is worth noting that, in the ADMS specification, adms:representationTechnique decribes a distribution, and not the dataset. Moreover, the [[ISO-19115]] code list of spatial representation types is available as a URI register from the INSPIRE Registry [[INSPIRE-SRT]].

    Based on this, GeoDCAT-AP specifies this information by using property adms:representationTechnique, with the spatial representation type URIs operated by the INSPIRE Registry [[INSPIRE-SRT]].

    This mapping is supported only in the extended mapping profile of GeoDCAT-AP.

    The spatial representation types defined in [[ISO-19115]] are listed in the following table. It is important to note that, as stated in the INSPIRE Data Specifications, the only spatial representation types in scope of INSPIRE are the following ones: “vector”, “grid”, and “tin”.

    ISO 19115 - MD_SpatialRepresentionTypeCode Description In scope of INSPIRE?
    vector vector data is used to represent geographic data Yes
    grid grid data is used to represent geographic data Yes
    textTable textual or tabular data is used to represent geographic data No
    tin triangulated irregular network Yes
    stereoModel three-dimensional view formed by the intersecting homologous rays of an overlapping pair of images No
    video scene from a video recording No

    Maintenance information - *not in ISO 19115 core

    In [[ISO-19115]], element “Maintenance information” is meant mainly to describe how frequently a resource is updated.

    In [[DCAT-AP-3]], the update frequency is expressed through dct:accrualPeriodicity, with the frequency codes defined in the the EU Vocabularies Frequency Named Authority List [[EUV-FREQ]], which can be partially mapped to the ones used in [[ISO-19115]], as shown in the following table.

    - semimonthly MONTHLY_2
    - threeTimesAMonth MONTHLY_3
    - semiweekly WEEKLY_2
    - threeTimesAWeek WEEKLY_3
    - - OTHER

    The [[ISO-19115]] code list of maintenance frequency codes is available as a URI register from the INSPIRE Registry [[INSPIRE-MF]].

    Based on this, maintenance frequency is specified in GeoDCAT-AP by using dct:accrualPeriodicity with the EU Vocabularies Frequency Named Authority List [[EUV-FREQ]].

    For the frequency codes not covered by the EU Vocabularies Frequency code list, the approach will be as follows:

    • In the core mapping profile of GeoDCAT-AP these codes will be ignored.

    • The extended mapping profile of GeoDCAT-AP will use the code list of ISO maintenance frequency codes operated by the INSPIRE Registry [[INSPIRE-MF]].

    Comparison between INSPIRE and ISO 19115-1:2014

    In [[?ISO-19115-1]] the concept of ‘Core metadata’ was removed; it was translated into a normative annex (Annex F) “Discovery metadata for geographic resources”. In the Annex F metadata elements for the discovery are listed in 2 tables:

    Spatial dataset and spatial dataset series

    The table below compares the core requirements of ISO 19115:2003 (see Table 3 in 6.5 of [[?ISO-19115]]), the requirements of INSPIRE for spatial dataset and spatial dataset series as defined in the Implementing Rules for metadata and the discovery metadata for geographic datasets and series (see Table F.1 in annex F of [[?ISO-19115-1]]). For those last metadata elements in the last field of the table the path is indicated. For each element, in brackets the obligation/max occurrence (3rd field).
