What is Defining Image Access about?

  • images as part of the scientific record
  • "universals" and "particulars"
  • the role of institutional repositories
  • Example: gene expression images
  • Discuss the need for domain-specific metadata

  • Image Bioinformatics Research Group (IBRG), Zoology, Oxford
  • Repository partners:
    • DSpace @ Cambridge
    • Southampton University, ECS and Library Services
    • Oxford University Library Services (OULS)
    • Imperial College Library
  • Consultant partners
    • UKOLN, Bath
    • Oxford University Computing Services
    • Oxford e-Research Centre
    • Imperial College Internet Centre
    • CCLRC e-Science Centre, Rutherford Laboratory


Project activities

What we learned

  • Not many image collections (yet)
  • Very little domain metadata
  • OAI-PMH is virtually a universal interface for repository metadata

BUT ...

  • OAI-PMH is not a practical choice for exposing domain metadata from institutional repositories (with current software systems); it may be practical for workgroup repositories.
  • a strategy for domain specific metadata based on composite or multipart objects, with one or more components containing metadata, may be easier to deploy uniformly.
  • Tools exist for converting OAI-PMH results to RDF, but no SPARQL query-rewriting endpoints for OAI-PMH have been discovered.
  • OAI-PMH does not provide mechanisms for searching on metadata values, so some level of preharvesting and pre-indexing is likely to be required, or use of a private repository search API.
  • The performance of D2R server is yet to be evaluated, in contrast to some commercial products, such as Virtuoso and AllegroGraph

Recommendations

Design proposal

This is a Powerpoint file that has been used to assemble a design proposal (part 2), a rationale upon which that proposal is based (part 1), and an outline of how implementation of that proposal might be approached.
