      • Each Record has a persistent and unique identifier

Catalogue Data Model

TNA Cataloguing Standard

  • ISAD(G) Derived Hierachical Arrangement

    • Description is inherited

  • Only 3 Possible (Mono-Hierarchical) Arrangements

TNA Cataloguing Standard

  • Attempted to Model Transfer of Records

DRI Catalogue Model

  • Derived from ISAG(G), PREMIS, and XIP

DRI Catalogue Model

  • Any (Mono-Hierarchical) Arrangement

DRI Catalogue Model

Choosing a New Model

  • Define a Common Vocabularly (for our Conceptual Model)

  • Try not to re-invent any wheels / Square peg vs round hole

  • Analyse Existing Models and Standards, key requirements:

    • Independent of Record Medium

    • Flexibility of Arrangement

      • Non/Mono/Poly-Hierarchical

      • Multiple Arrangements

    • Abstract Record, Concrete Manifestation(s)

      • Redaction

      • Surrogates

    • Provenance

    • Extensible / Open World

Existing Models and Standards

  1. TNA-CS13 (TNA Cataloguing Standard 2013)

  2. DRI Catalogue Model

  3. BIA (Business Information Architecture)

  4. EAD (Encoded Archival Description)

  5. DCAT (Data Catalog Vocabulary)

  6. FRBR (Functional Requirements for Bibliographic Records)

  7. RDA (Resource Description and Access)

  8. BIBFRAME

  9. Europeana

  10. RiC (Records in Context)

  11. Matterhorn RDF Model

Top 3 Models

  1. BIBFRAME Lite + Archive

    • Against - bibliographic/library centric domain

    • Against - single custom ontology

  2. RiC-O

    • For - ICA implementation of RiC-CM

    • Against - single custom ontology

  3. Matterhorn RDF

Project Omega, Next Steps...

  • Define URI for Records

    • RDF Unique Persistent Identifiers. Resolvable ???

    • Unlikely to replace CCR / GCR ???

  • Export data into Matterhorn RDF

    • ILDB

    • SAR

  • Implement (partial) PROCat Replacement

    • Backend is an API fronting the Database

    • Front-end only speaks to API

  • Document our Catalogue Model and Guidelines

  • Stretch goal: import some DRI Born Digital records

Ultimate Goal for World
  Archives Domination:

A linked-data knowledge graph of the entire organisation's assets.
