Digital Repositories interoperability

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

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

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.

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
