Title: Preservation metadata and the Cedars project


1
Preservation metadata and the Cedars project
  • Michael Day
  • UKOLN UK Office for Library and Information
    Networking
  • University of Bath
  • http//www.ukoln.ac.uk/
  • m.day_at_ukoln.ac.uk
  • Metadata for Long-Term Preservation in NEDLIB
  • Bibliothèque nationale de France, Paris, 25
    February 2000

Presentation Outline
  • The UK context
  • The Cedars project
  • Aims and objectives
  • Relationship with the OAIS model
  • The Cedars outline metadata specification
  • A JISC/NSF funded project about emulation
    strategies (CAMiLEON)

3
The UK Context
  • CPA/RLG Task Force on the Archiving of Digital
    Information (1996)
  • UK response co-ordinated by the Joint Information
    Systems Committee, the British Library and the
    National Preservation Office.
  • Warwick strategy workshops (1995, 1999)
  • Digital Archiving Working Group
  • Digital Preservation Focus
  • Public Record Office
  • Electronic Records in Office Systems (EROS)
  • National Digital Archive of Datasets (NDAD)

Cedars - CURL exemplars in digital archives
5
Cedars project (1)
  • Consortium of University Research Libraries
    (CURL)
  • interested in the roles and responsibilities of
    research libraries with regard to digital
    preservation.
  • JISC eLib Phase 3
  • Hybrid Libraries, Large Scale Resource Discovery
    and Digital Preservation
  • Cedars project
  • funded by JISC through the CURL libraries from
    April 1998 for 3 years

6
Cedars project (2)
  • A CURL project led by the universities of
    Cambridge, Leeds and Oxford
  • Mixture of libraries and computing services
  • Three broad groups
  • Data preservation strategies (Leeds)
  • Content issues (Cambridge)
  • Access issues - metadata (Oxford)
  • In collaboration with
  • Arts and Humanities Data Service, British
    Library, National Preservation Office, Research
    Libraries Group, UKOLN, publishers, etc.

7
Cedars project (3)
  • Objectives
  • To promote awareness
  • To identify and disseminate
  • appropriate strategies for collection management
  • appropriate strategies for long-term preservation
  • Based on a realistic sampling of current digital
    resource collections

8
Cedars metadata review (1)
  • Metadata for preservation (AIW01)
  • Produced by UKOLN (August 1998)
  • Identified and reviewed relevant projects and
    associated issues
  • The OAIS Model
  • PANDORA
  • The Pittsburgh Project
  • RLG Working Group
  • http//www.ukoln.ac.uk/metadata/cedars/AIW01.html

9
Cedars metadata review (2)
  • Four main types of metadata
  • Technical metadata
  • Recording technical details about the original
    hardware and software environment to support
    preservation strategies
  • Rights management metadata
  • Recording intellectual property rights ownership,
    deposit agreements, etc.
  • Intellectual preservation metadata
  • Preserving integrity and authenticity
  • Resource discovery metadata

10
The OAIS model (1)
  • ISO Reference Model for an Open Archival
    Information System (OAIS)
  • Consultative Committee on Space Data Systems
    (CCSDS)
  • Draft Recommendation (May 1999)
  • Establishes a common framework of terms and
    concepts which comprise an OAIS
  • Facilitates the description and comparison of
    archives
  • A basis for further standardisation
  • A basis for conformance

Information Packages
  • Archival Information Package (AIP)
  • Content Information
  • The information that is the primary object of
    preservation. Containing a Digital Object and any
    Representation Information (technical metadata)
    needed to transform this object into meaningful
    information
  • Preservation Description Information (PDI)
  • other information (metadata) which will allow
    the understanding of the Content Information over
    an indefinite period of time
  • Terms defined in CPA/RLG report

Cedars and OAIS
  • The Cedars project ...
  • has adopted the OAIS taxonomy as a means of
    thinking about metadata and for the preliminary
    structure of the draft outline specification of
    preservation metadata
  • the data preservation strategies group has
    developed a model based on OAIS and outlined a
    blueprint for Representation Information.

  • nasa2000/nasa2000.html

15
Cedars metadata (1)
  • Process
  • Elements identified from selected initiatives
    described in metadata review
  • Initial draft, structured according to OAIS
    taxonomy (February 1999)
  • Extended debate about the role of OAIS
  • First review draft (December 1999)

16
Cedars metadata (2)
  • Reference Information
  • Resource Description
  • Title, Creator, etc.
  • Reference labels
  • Existing metadata
  • Context Information
  • Reason for Preservation
  • Related Information Objects

17
Cedars metadata (3)
  • Provenance Information
  • History of Origin
  • Management History
  • Use History
  • Known Operating Environments
  • Rights Management
  • Fixity Information
  • Checksum

18
Cedars metadata (4)
  • Future developments
  • Initial draft specification
  • Most comments have now been received
  • Generally favourable response
  • Some serious issues that need to be addressed
  • Revised draft specification
  • For public consultation (from April)
  • Final project deliverable
  • Due June 2000

19
CAMiLEON project
  • Emulation Options for Digital Preservation
  • JISC/NSF International Digital Libraries
    Programme
  • University of Michigan
  • University of Leeds (Cedars)
  • Testing emulation strategies for digital
    preservation
  • Now called CAMiLEON
  • Creative Archiving at Michigan and Leeds
    Emulating the Old on the New

20
Conclusions
  • For the project
  • How successful has Cedars been when compared with
    its aims and objectives?
  • e.g., the production of best practice guidelines
    for metadata
  • What will Cedars be able to demonstrate?
  • Will this lead to the development of digital
    preservation services?
  • For OAIS
  • Terminology not widely understood
  • Need to know more about how it interacts with
    other models

    Commission (formerly the British Library Research
    and Innovation Centre), the Joint Information
    Systems Committee (JISC) of the UK Higher
    Education Funding Councils, as well as by project
    funding from the JISCs Electronic Libraries
    (eLib) Programme and the European Union. UKOLN
