Lifecycle Metadata for Digital Objects

September 11, 2002

Major archival and digital library metadata schemes


Nhprc initiative 1991
NHPRC Initiative, 1991

  • Research Issues in Electronic Records

  • http://www.archives.gov/nhprc_and_other_grants/electronic_records/research_issues_report.html#recommendations

  • 1992 review of research agenda, MN Historical Society

  • 1992-1996

  • “Business Acceptable Communications”

  • “Warrant” for functional requirements

    • Legal

    • Records Management

    • Management

    • Medical

    • Archival

  • Evaluating administrative recordkeeping systems at IU

  • Testing functional requirements

  • Mapping metadata requirements

    • Elimination of “metadata encapsulated objects”

    • Reduction in structural metadata

    • Pulled back from record-level metadata to record, file, class levels

    • Influenced by MoReq

    • Lacks understanding of implementation issues


Interpares project
InterPARES Project

  • Initially a University of British Columbia project that led to DoD STD 5015.2

  • Aim to establish characteristics of a reliable and authentic electronic record

  • InterPARES is international project funded by NHPRC, SSRC, etc.

  • Aim to establish rest of record life cycle


Interpares case studies
InterPARES case studies

  • Examine digital recordkeeping systems in wide variety of contexts worldwide

  • Qualitative methods used to discover how records are used, carry out functional analysis

  • Data used to provide basis for modeling preservation processes


Interpares basis in diplomatics
InterPARES basis in diplomatics

  • 19th-century method for establishing genuineness of documents

  • Defines four types of records:

    • Dispositive (form is essence of evidence)

    • Probative (written form part of evidence)

    • Supporting (written form discretionary, procedurally linked to action)

    • Narrative (provide context)


Interpares authenticity template
InterPARES Authenticity template

  • Documentary form

    • Extrinsic elements

    • Intrinsic elements

  • Annotations

  • Medium

  • Context


Interpares findings 2002
InterPARES findings, 2002

  • Hopes for a clear typology dashed after four rounds

  • Contemporary systems too fluid for model

    • No fixed form or content

    • No annotations

    • Embedded in social contexts

    • Managed procedurally


Dublin core metadata initiative
Dublin Core Metadata Initiative

  • Supported by OCLC

  • Primarily a surrogate/discovery metadata scheme

  • Does not aim to document everything

  • Useful for management of active digital objects

Dublin core development
Dublin Core development

  • Initial development of simple elements

  • Subelements and user communities

  • Warwick Framework

  • RDF and XML

  • Example:


Metadata encoding and transmission standard mets
Metadata Encoding and Transmission Standard (METS)

  • Developed out of LoC’s MOA project

  • Designed to support maintenance of library of digital objects

  • Three overall types of metadata

    • Descriptive

    • Administrative

    • Structural


Mets descriptive metadata
METS Descriptive metadata

  • External (e.g., finding aid)

  • Internal (part of the document)


Mets administrative metadata
METS Administrative metadata

  • Technical metadata

  • Intellectual property rights metadata

  • Source metadata (re analog source)

  • Digital provenance metadata

    • Relations between files

    • Migration/transformation data


Mets structural metadata
METS Structural metadata

  • File groups list

  • Structural map (defines relations between files and METS element structure)

  • Behavior segment (associates executable methods with specific content elements, e.g. for display)


Mets and xml
METS and XML

  • The METS XML schema

  • http://www.loc.gov/standards/mets/mets_xsd/mets.html

  • Why is it all so complicated?

  • How can anyone ever keep track of all this metadata?
