1 Issues and approaches to preservation metadata Michael Day UKOLN: UK Office for Library and Information Networking University of Bath http://www.ukoln.ac.uk/ m.day@ukoln.ac.uk

2 2 Issues and approaches to preservation metadata Michael Day Joint RLG and NPO Preservation Conference: Guidelines for Digital Imaging, University of Warwick. 28-30 September 1998 http://www.ukoln.ac.uk/events/sept-conf98/

3 3 Presentation Outline Context metadata digital preservation Cedars project Preservation metadata issues Some current approaches and data models

4 4 Background - general Metadata (Making of America II): Descriptive metadata - e.g. Dublin Core, EAD, MARC Structural metadata Administrative metadata Preservation metadata is a specialised form of administrative metadata

5 5 CURL Exemplars in Digital Archives (Cedars) Project funded by JISC (eLib) through the Consortium of University Research Libraries (CURL)

6 6 Cedars Objectives To promote awareness of issues To identify and disseminate - appropriate strategies for collection management appropriate strategies for long-term preservation To produce demonstrators and documentation (guidance)

7 7 Digital imaging Motivations: Improving access Preservation (continuing access) Suitable for long-term preservation? Metadata issues What metadata exists already? How should this be associated with the image

8 8 Digital preservation (1) Technical preservation strategies Hardware and software conservation Emulation Migration All of these strategies depend upon the identification and collection of relevant metadata

9 9 Digital preservation (2) Authentication Intellectual preservation Identifiers Cryptographic techniques Rights management Extremely important problem that needs urgent solution - metadata has potential role.

10 10 Digital preservation (3) Integration with other metadata: Resource discovery Existing catalogues and finding aids Collection Management Ensuring that the metadata is itself managed and migrated

11 11 Cedars metadata study Metadata for preservation Preliminary version - August 1998 Looked at a variety of projects and initiatives from different sectors: http://users.ox.ac.uk/~cedars/Papers/ aiw01.html

12 12 Metadata initiatives RLG Working Group on Preservation Issues of Metadata Final Report, May 1998 Identified elements and published sample implementations http://www.rlg.org/preserv/presmeta.html

13 13 RLG WG elements Date Transcriber Producer Capture device Capture details Change history Validation key Encryption Watermark Resolution Compression Source Color Color management Color bar / Grey scale bar Control targets

14 14 Data Models Important - Open Archival Information System (OAIS) PANDORA Resource Description Framework (RDF) Cedars Access Issues Working Group

15 15 Conclusions Preservation metadata is important Need for integration of preservation metadata with other forms of metadata Cedars is attempting to study issues and develop demonstrators Also to formulate guidance for good practice
