Panel on digital preservation

2013

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

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.

Digital objects are more vulnerable to destruction or loss as compared to conventional library materials. Issues like format obsolescence, software obsolescence, hardware obsolescence and storage media fault/deterioration are some of the major threats that make the digital resources vulnerable to destruction. Digital resources require special attention and application of strategies for long term retention and accessibility. The purpose of this paper is to outline the basic issues that threaten the retention and accessibility of digital resources in the long term. The paper also attempts to provide an outlook of the possible solutions for overcoming these issues.

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.

Selection and metadata issues which surround the preservation of digital information are discussed, in particular, the assignment of "collection levels" to Web materials to ensure preservation, and some Preservation Metadata Element Sets (PMES) which have been identified as informed by the Open Archival Information System (OAIS) Reference Model. A metadata framework that can support a broad range of digital preservation activities-a Core PMES-is proposed, together with a general criteria based on "collection levels" to express preservation decision and responsibility for the resource at the time of selection.

Libraries are storehouse of large number of documentary sources such as records, manuscripts, books, films and other materials. Since these materials with the passage of time are subject to deterioration and decay. Hence all these materials need to be preserved using different mechanisms so that these materials are available to the future generations also. Due to huge advances in information communication technologies (ICTs), there has been an astronomical growth of e-resources -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. This paper discussed the Methods and Technology of digital preservation analysis the various types of preservation in traditional documents as well as preservation of digitized forms of documents using latest technologies.
