State of ELF • Technology is rapidly maturing • Relatively robust • Starting to see real-world implementation • Demonstrable cross-searching • Move to federated searching • “Technology is not a problem, we are getting there” JISC CETIS Conference, Oxford, November 2004

Technical Issues • Identifiers (deciding) • Rights Management • Metadata • Automated creation • Distributed metadata creation • Decoupling metadata and content • Relevancy in searches • Performance of distributed search JISC CETIS Conference, Oxford, November 2004

ELF Warning • “Federated repository implementations failed in the past because the technology was immature. The technology is now maturing, but the business and governance issues will kill us. ” - Dan Rehak JISC CETIS Conference, Oxford, November 2004

ELF Needs & Problems • “Seamless” integration to the real world • Embedding repositories in everyday practice • Managing the business process • Institutional policy • Understanding & enabling workflows (how to manage “stuff”) • Motivation to contribute • Staff development • Technical policies of institutions impede interoperability e. g. Security JISC CETIS Conference, Oxford, November 2004

ELF Advice (to JISC) • Lobby institutions to be more open with resources • Address governance issues • Identifiers, DRM infrastructure • Support training and staff development • “Teach teachers how to search” • Look at applicable technologies from other areas (libraries, grid) • “Don’t always look for technical solutions” • Look at presentation of information • More prototyping, mock-ups and usability work JISC CETIS Conference, Oxford, November 2004

More ELF Advice • Define a common language to discuss repositories i. e. What do we mean by • “repository” • “content” • Look for commonality across representations (of frameworks) • Drivers to promote practice • cf motivation of open source • Focus on identifying user needs JISC CETIS Conference, Oxford, November 2004
