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?

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……

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….

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
