Libraries, metadata and preservation of electronic resources

2013

In the space of less than a decade, preservation metadata has evolved from a research topic to an integral part of best practice for the long-term stewardship of digital materials. The first edition of this report chronicled the evolution of preservation metadata from concept to standard, ending with the release of the PREMIS Data Dictionary. In second edition, this report focuses on new developments in preservation metadata made possible by the emergence of PREMIS as a de facto international standard. The report is intended for digital preservation practitioners interested in learning about the key developments in preservation metadata, especially as these developments concern the PREMIS Data Dictionary; the report will also be of interest to anyone seeking to learn more about the general topic of preservation metadata. The focus of work in preservation metadata has shifted from theory to practice; consequently, this report focuses on the key implementation topics that have emerged since the publication of the PREMIS Data Dictionary, including revisions of the Data Dictionary; community outreach; packaging (with a focus on METS), tools, PREMIS implementations in digital preservation systems, and implementation resources. The report also suggests some areas which future work in preservation metadata should address.

CEDARS (CURL Exemplars in Digital ARchiveS) is a UK digital preservation project funded by JISC through eLib. Lead sites in the project are the Universities of Cambridge, Leeds and Oxford. The project aims to promote awareness of the importance of digital preservation, to produce strategic frameworks for digital collection management policies and to promote methods appropriate for long-term preservation. An important strand of CEDARS will concern metadata.

Digital information in any form is at risk. Software and hardware become obsolete, and versions and file formats change, making data inaccessible. Data stored in even the simplest form are in danger due to computer media degradation and obsolescence. Online information such as e-journals and databases are susceptible. They may become partially or entirely unreadable, and may not be recoverable by the time the problem is detected. Preservation strategies such as emulation (keeping alive the software and hardware needed to access a digital object), migration (converting the digital object to new versions and formats), and other longterm archival methods have been proposed . Models such as the Open Archival Information System (OAIS) provide an architecture for conducting digital preservation research and experimentation . The importance of preservation metadata has been recognized by a number of groups and efforts to develop and deploy metadata standards are underway .

Due to huge advances in information communication technologies (ICTs), there has been an astronomical growth of e-resources-e-journals, e-books, online databases and so on; libraries spend phenomenally on acquisition of these e-resources as these are very popularly used by the students and researchers. Unfortunately, this growth is accompanied by many threats. Digital content (of the e-resources) is fragile and not durable. Its accessibility and use by future generations depends on technology which very rapidly evolves and changes. Hence, ensuring access of e-resources for future generation of users is a big challenge for libraries. The present paper highlights various problems of digital content and elaborates how digital preservation is more demanding and challenging than preserving print copies of journals. It also gives a bird's eye view of various projects initiated for archiving digital content of scholarly journals.

There is a lack of durable thinking on digital longevity. For this we require cross-domain communication and acceptation of standardized concepts, procedures, document formats and IT-tools. Four kinds of standards are required for preservation of digital documents over an indefinite period of time: standards for the architecture, document format standards for preservation, metadata standards for preservation of the access and

Abstract The Fifth International Conference on Preservation of Digital Objects was held at the British Library on September 29–30, 2008, with the theme “Joined Up and Working: Tools and Methods for Digital Preservation”. Topics ranged from the technical foundations of digital preservation through preservation system architectures to the organizational and policy issues facing the custodians of digital resources.

Authenticity is defined as the management of provenance information about the creation of the record. Integrity is defined as the ability to create an authentic copy. Chain of custody tracks all processing done to the record, including migration to new storage systems or to new data encoding formats. Digital preservation addresses the challenge of technology evolution by managing preservation properties independently of the choice of software and hardware systems. Preservation properties include the names used to identify archivists, records, and storage systems, and the preservation metadata which includes provenance information and administrative information about record management. The display and manipulation of digital data is maintained through the use of representation information that describes how the record can be parsed and interpreted. Digital preservation environments implement trustworthiness assessment criteria, enabling verification that the preservation properties are maintained over time. HISTORICAL BACKGROUND The preservation community bases digital preservation upon the same concepts that are used to preserve paper records. The preservation environment manages the authenticity, integrity, and chain of custody of the digital records. At least four approaches have been implemented that define the digital preservation processes and policies that are needed to maintain authenticity and integrity. 1) Diplomatics defines the required provenance information that describes the institution, event, and ingestion information associated with the documentation of an event. Examples of events are treaties and government communiqués. The records are assumed to be held forever. 2) The US National Archives and Records Administration associates records with a life-cycle data requirements guide. Each record is associated with a record group (institution), a record series (the set of records governed by a submission agreement), a file unit, and an entity. Each record series has a defined retention and disposition schedule. The arrangement of the records is governed by the submission order in the record series. Standard preservation processes include appraisal, accession, arrangement, description, preservation, and access. 3) The digital library community manages preservation within the context of a collection, with the required preservation metadata and the arrangement governed by the purpose under which the collection was formed. 4) The continuum model manages records within an active access environment. Records that are generated for one record series may be used as the basis for generating a new record series. The relationships between records within the multiple record series are tracked as part of their provenance. Each of these four communities imposes the preservation processes and preservation policies required to enforce their goals.

Libraries, archives, and museums play a critical role in organizing, preserving, and providing access to the cultural and historical resources of society. Digital technologies are used increasingly for information production, distribution, and storage. The institutions that have traditionally assumed responsibility for preserving information face technical, organizational, resource, and legal challenges in taking on the preservation of digital holdings. Maintenance will be critical to digital libraries; especially those who promote broad access to diverse, informal materials. If ignored, maintenance issues within the digital library, especially those relating to its materials will threaten its usefulness and even its long-term viability. We perceive the maintenance problem to be both technical and institutional, and this paper considers the preservation and maintenance of the digital library. The paper examines collection maintenance from several vantage points, including software architecture and the type of collection. The paper ends with an examination of potential technical solutions.

Libraries are engaged in the creating and marinating digital libraries all over world. A digital library that deals with data those are born digital as well as those that have been digitized from their analogue form. So there is a need to preserve digital resources for future use. Since the nature of digital data or resource is intangible and it cannot see in necked eyes so there is a need to preserve and organized them in such a way that we can get easily access to them. Developing preservation process for digital resources will require the integration of new methods, policies, standards, and technologies. This paper aims to give an overview in digital preservation, highlights some strategy and standards efforts. Keywords: Digital Preservation, Obsolescence, OAIS

Effective digital preservation depends on a set of preservation services that work together to ensure that digital objects can be preserved for the long-term. These services need digital preservation metadata, in particular, descriptions of the properties that digital objects may have and descriptions of the requirements that guide digital preservation services. This paper analyzes how these services interact and use this metadata and develops a data dictionary to support them.

Preservation metadata are in the core of the activities which guarantee long term sustainability and usability of digital resources. Currently the field of preservation metadata is more advanced in theoretical issues, with most of the effort invested in developing preservation schemas and studying interoperability issues. Recent research trends in automated metadata generation are not well integrated into preservation metadata workflows although they, as with all other types of metadata, can not be created manually at a pace compatible with that at which digital resources are being created. In this paper we investigate where the cross section of the current needs in preservation metadata field and the achievements in automated metadata generation lies. We also place this in the context of the preservation activities framework of the DELOS reference model.
