Title: Digital Repositories: interoperability


1
Digital Repositories interoperability
common servicesClosing RemarksDr Liz Lyon,

2
Some points from the Crete workshop
  • Currently roles in scholarly communications are
    evolutionary
  • Need to have a more revolutionary approach
  • Repositories within wider frameworks in context
  • Repository activities across e-learning,
    e-research and e-administration
  • Need to address architectural challenges, looking
    for common abstractions
  • Repository reference model
  • Inhouse or off-the-shelf?

3
Some points from the Crete workshop
  • Different drivers conflicting requirement
  • Maturity and robustness of existing tools
  • Prototype development to extend functionality
  • Migration of content between repositories
  • Cultural organisational challenges
  • Communication issues
  • Between service providers and data providers
  • Preservation strategies and risk analysis

4
JISC / SURF / CNI conference on Institutional
Repositories
  • Survey of national IR developments
  • Panels looking at fragmentation, content,
    organisation and workflow, national policy
  • Keynotes (Tony Hey and Mark Kornbluh)
  • 4 breakout sessions
  • Technical infrastructure (Liz Lyon Herbert
    Van der Sompel)
  • Faculty issues A Impact , citations rights
    (Tim Brody Charles Oppenheim)
  • Faculty issues B Awareness (Alma Swan survey)
  • Policy issues (Ann Wolpert Lorna Campbell)
  • Commentary and close from Cliff Lynch
  • Presentations will be on SURF Web site

5
Assuring permanent open access to the records of
science the humanities?
  • Long term access to primary data
  • Increasing data volumes from eScience and
    Grid-enabled / cyberinfrastructure applications
  • Changing research paradigm data-driven science,
    big science
  • Observational data, simulations, large-scale
    experimentation, computations
  • Multi-media resources, statistical data,
    surveys, geo-spatial data

6
Taxonomy of data collections
Evolution
  • Research collections jumping robots
  • Community collections Flybase at Indiana
    (with UC Berkeley )
  • Reference collections Protein Data Bank
  • Source NSF Long-Lived Digital Data Collections
  • Draft report March 2005

JISC/SURF/CNI Technical Issues
  • Scholarly communications, lifecycles and value
    chains
  • Research data is diverse, increasing rapidly in
    volume and complexity e-Science
  • Repository collections are dynamic and evolve
  • Embedding in workflow is critical scholarly
    communications, research practice, learning
  • Linking research data to publications and
    learning
  • Knowledge services will generate new discoveries
    based on repository content
  • Repository solutions must scale M2M processing
    will become the norm
  • Complex digital objects are the norm.

9
JISC/SURF/CNI Technical Issues
  • Federated repository architectures
  • Repository registry proposed
  • Object registry proposed
  • Multiple persistent identifier schemes
  • Multiple identifiers per object
  • Name authority and author registries
  • Terminologies across domains for meaningful
    resource discovery
  • Rights expression languages
  • Provenance and versioning

Next steps?
  • Knowledge Extraction Semantic Interoperability
    cluster
  • We need to share information about current
    research interests, activities and projects more
    effectively
  • Explore possibility of Delos database of research
    activity
  • In partnership with others JISC???
  • Initiate Delos forum using post-workshop mailing
    list
  • Report on Digital Repositories
  • Cluster Web site development
  • Continue discussion and debate
  • Greater integration of research activity
