  1. IESR: A Registry of Collections and Services Ann Apps MIMAS, The University of Manchester, UK

  2. Outline • Purpose of JISC Information Environment Service Registry (IESR) • IESR content description • IESR services • Using IESR for metasearch • Future direction of service registries • Integration Issues SRU Integration Workshop

  3. Why IESR? • JISC Information Environment: • Collections of resources for researchers, learners, teachers in UK • Single central registry – m2m access • Improve awareness and access • Funded by JISC: • MIMAS, UKOLN, University of Liverpool • Registry developed and hosted by MIMAS SRU Integration Workshop

  4. IESR Content • Descriptions of: • Collections of resources • Informational Services that provide access • Agents: Owners / Administrators • Transactional Services • Supplied by resource providers • Check by IESR content manager SRU Integration Workshop

  5. IESR Entities Collection provides access owns Service Agent administers SRU Integration Workshop

  6. IESR Entity Description • Entities identified with URI • Described by metadata • Metadata defined by Application Profile • Semantics • Occurrence • Searchable SRU Integration Workshop

  7. IESR Collection Metadata • Based on RSLP Collection Description • Simplification for electronic resources • Consistent with: • DCMI Collection Description Application Profile • NISO MI Collection Description • Vocabularies for property values SRU Integration Workshop

  8. SRU Integration Workshop

  9. IESR Service Metadata • More than RSLP CD ‘locator’ • Bespoke IESR scheme to support discovery and registry application • Single access method: • SRU, Z39.50, SOAP, OAI-PMH, Web/CGI • Location URL • Interface property for some service types using appropriate schema SRU Integration Workshop

  10. SRU Integration Workshop

  11. Other Service types • SOAP: Locator: access URL; Interface: WSDL • SRU: Interface: ZeeRex • SRW: Interface: ZeeRex; WSDL • OAI-PMH: Locator: BaseURL • OpenURL: Locator: BaseURL • Web CGI: Interface: arguments • Web page: Locator: URL SRU Integration Workshop

  12. IESR Agent and Administrative Metadata • Agent: contact details • Administrative: • Included with every entity • IESR includes: • creating organisation, publisher: IESR • latest modification date • rights to reuse descriptions: Creative Commons SRU Integration Workshop

  13. IESR Services • Z39.50 • Search via Bib-1 attributes • Results: text (SUTRS); composite XML • OAI-PMH for harvesting: entity XML • OpenURL Link-To Resolver • Implements IESR identifier resolution • Web Search and Browse • Data Supply Editor SRU Integration Workshop

  14. Future Services • SRU • Web Services SOAP / SRW (planned) • RSS • UDDI (under investigation) • Mapping IESR data to UDDI • Prototype registry SRU Integration Workshop

  15. Using IESR: Portal Metasearch • Social Science portal discovers collections with e.g. SRU services • Provides cross-search to end-user using e.g. SRU • Portal builder doesn’t need to know about all resources • Users discover collections unaware of • Alternative: OAI-PMH harvest SRU Integration Workshop

  16. Distributed Service Registries • Scope of IESR • Distributed / federated model • Each node describes own resources • How to cross search? • Metasearch; UDDI; OAI-PMH harvest • IESR collaboration with OCKHAM in US • Searching is local • Replication by OAI-PMH harvest SRU Integration Workshop

  17. Integration Issues • Resources have Web interface only • IESR covers all service protocols: • Few SRU services in JISC IE • Contributing technical service details • Use of Service Registry still visionary • Dynamic use with SOAP not feasible • NISO Web Services and Practice WG • SRW • Description of authentication details SRU Integration Workshop

  18. Integration Issues: Sharing • Sharing records needs common schema • NISO Metasearch Initiative Collection Description: basis of IESR and OCKHAM • Rights issues • Simplified with common CC licence • Cross searching federated registries: • Metasearch? Harvest? • UDDI • Loss of full collection description SRU Integration Workshop

  19. Recommendations • Encourage the provision of m2m interfaces for resources • Advertise SRU as low barrier solution • Register SRU services in online directories to encourage use SRU Integration Workshop
