Digital Repositories: interoperability & common services Closing Remarks Dr Liz Lyon, UKOLN, University of Bath, UK [email protected] 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? 13 May 2005 Digital repositories workshop 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 13 May 2005 Digital repositories workshop 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 13 May 2005 Digital repositories workshop 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…… 13 May 2005 Digital repositories workshop 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 13 May 2005 Digital repositories workshop Repository evolution: 1971 Research collection <12 files 2005 Reference collection >2700 structures deposited in 6 months 13 May 2005 Digital repositories workshop JISC/SURF/CNI Technical Issues 1. 2. 3. 4. 5. 6. 7. 8. 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…. 13 May 2005 Digital repositories workshop JISC/SURF/CNI Technical Issues 1. 2. 3. 4. 5. 6. 7. 8. 9. 13 May 2005 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 Digital repositories workshop Presentation services: subject, media-specific, data, commercial portals Data creation / capture / gathering: laboratory experiments, Grids, fieldwork, surveys, media Resource discovery, linking, embedding Data analysis, transformation, mining, modelling Searching , harvesting, embedding Aggregator services: national, commercial Resource discovery, linking, embedding Learning object creation, re-use Harvesting metadata Research & e-Science workflows Deposit / selfarchiving Learning & Teaching workflows Repositories : institutional, e-prints, subject, data, learning objects Validation Publication The scholarly knowledge cycle. May 2005 Liz13Lyon, Ariadne, July 2003. Deposit / selfarchiving Institutional presentation services: portals, Learning Management Systems, u/g, p/g courses, modules Resource discovery, linking, embedding Peer-reviewed publications: journals, conference proceedings Digital repositories workshop Validation Quality assurance bodies 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 13 May 2005 Digital repositories workshop Thanks to many people.
