Context
• Joint Information Systems Committee (JISC) provides ICT infrastructure and advice for United Kingdom universities and colleges
– Funds a large number of projects, as well as electronic collections for the research, learning and teaching communities

Current digital landscape
…a vast and sometimes bewildering range of potential sources of electronic information.
Little wonder, then, that many users remain unaware of their existence or fail to discover their value for their own learning, teaching or research.

JISC Information Environment
• aims to make it easier for the user to find relevant information and learning resources
• will enable presentation, delivery and use of online resources in ways tailored to support individual and institutional requirements in learning, teaching and research

Shared Services
To enable portals and other services to deliver diverse digital resources, machine-readable information about services, content, rights and users is required to act as the “glue” between portals and the content itself.

IESR
• A registry of the electronic resources available within the JISC’s Information Environment
• Contains information about:– the resources themselves– how to access the resources– the resource provider(s)
• Is accessible by other applications via machine-to-machine interfaces
2005-04-05 CNI Spring 2005 10
Project history
• Partners – MIMAS, University of Manchester– UKOLN, University of Bath– Cheshire Development Team, University of Liverpool
• Funded by JISC in three phases since November 2002
• Current phase started 1 March 2005
2005-04-05 CNI Spring 2005 11
Collections
• 259 resources currently described, submitted by:– AHDS– Edina– MIMAS– Resource Discovery Network– UK Data Archive– UK Mirror Service (now the JISC National Mirror Service)
• In current phase, we will be expanding our content to encompass non-JISC service providers: e.g.– institutional resources (digital repositories, OPACs)– resources of other UK Common Information Environment
partners (National Archives, British Library, National Health Service, BBC)

Using IESR
• Portal (amalgamated set of resources)– Metasearch on behalf of user
• Portal builder doesn’t need to know about resources• Users discover collections unaware of
– Harvest IESR records• Local service registry• Knowledgebase (convert to appropriate format)• Local configuration file
– Link to Web Search - general resource discovery
• RSS Aggregator: news feeds; new data alerts• Reuse collection description
