Linked open copac archives hub

Linked Open Copac & Archives Hub

JISC-funded project (under JISCexpo - exposing digital content for education and research)

September 2010 – August 2011

Staff from Mimas, UKOLN, Eduserv

Additional expertise from Talis, OCLC, Library of Congress


Project aims

Project Aims

Put archival and bibliographic data at the heart of the Linked Data Web, making new links between diverse content sources, enabling the free and flexible exploration of data and enabling researchers to make new connections between subjects, people, organisations and places to reveal more about our history and society.

Make a collection of resources available on the Web as structured data, in particular linked data, where a case can be made that it would benefit teaching, learning, research, administration and/or knowledge transfer in UK higher education

Develop a prototype with instructional step-by-step demonstration and documentation to show how the structured content can be used by 3rd party tools and services

Explore and report on the opportunities and barriers in making content structured and exposed on the Web for discovery and use. Such opportunities and barriers may coalesce around licensing implications, trust, provenance, sustainability and usability

The data copac

The Data: Copac

  • Merged union catalogue of the holdings of over 60 UK libraries

  • Over 50 million records

  • Consolidated records

  • MODS XML (not MARC)

A Copac consolidated record created from 5 contributed records. Lines show how contributed records match with one another.


The data archives hub

The Data: Archives Hub

  • Descriptions of archive collections from over 200 UK repositories

  • Nearly 25,000 descriptions – collection-level and multi-level

  • EAD (Encoded Archival Description)


Challenges variance

Challenges: variance

  • Data from many sources – should adhere to

    • Standards

      • AARC2

      • ISAD(G) BUT

    • Differences in implementation

  • Data comes from contributors

    • Not ours to redistribute!

  • Concerns

    • Provenance

    • Trust

    • Control

  • Consulted

    • Liaised with contributors and stakeholders

  • Result

    • Released test data set as CC0

Visualisation prototype

Visualisation Prototype

  • Using Timemap –

    • Googlemaps and Simile

    • http://code.google.com/p/timemap/

  • Early stages with this

  • Will give location and ‘extent’ of archive.

  • Will link through to Archives Hub


What next

What Next?

  • Linking Lives

    • name-based approach into the data

    • integrating archival resource with other resources

    • DBPedia, VIAF, Copac...

    • route into archives for different audiences?

    • issues around trust and provenance to be explored


Finally

Finally…

The LOCAH data is open for use…

…please play with it!
