  1. Disseminating Service Registry Records 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 • The future ELPUB2006

  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 ELPUB2006

  4. IESR Content • Descriptions of: • Collections of resources • Made available via Informational Services • Agents: Owners / Administrators • Transactional Services • Contributed by resource providers • QA check by IESR content manager • IESR will encourage maintenance ELPUB2006

  5. IESR Entities Collection provides access owns Service Agent administers ELPUB2006

  6. IESR Entity Description • Entities identified with URI • Described by metadata • Metadata defined by Application Profile • Semantics • Occurrence • Searchable • AP for human reading • More restrictive than XML schema ELPUB2006

  7. IESR Collection Metadata • Based on RSLP Collection Description • Simplification for electronic resources • Consistent with: • DCMI Collection Description Application Profile • NISO MI Collection Description Specification • Vocabularies for property values • Dewey subject backbone ELPUB2006

  8. ELPUB2006

  9. IESR Service Metadata • A few IESR properties 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 ELPUB2006

  10. ELPUB2006

  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 ELPUB2006

  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 ELPUB2006

  13. IESR Services • Z39.50: composite XML • OAI-PMH for harvesting: entity XML • OpenURL Link-To Resolver • Implements IESR identifier resolution • Future: SRU; SOAP/SRW; RSS; UDDI • Web Search and Browse • Data Editor for Contributors ELPUB2006

  14. IESR Users • DL Portal; Metasearch Application • amalgamated set of resources • IESR provides: • Discovery of resource collections • Up-to-date details of access to collections • Discovery of transactional services • RSS: personal DL portal • OpenURL resolvers ELPUB2006

  15. Portal Metasearch Scenario • Researcher: find family health datasets • Social Science portal discovers collections with e.g. Z39.50 services • Portal provides cross-search to user • Portal builder doesn’t need to know about all resources • Users discover collections unaware of • Alternative: Static use by Portal builder ELPUB2006

  16. Harvesting IESR • OAI-PMH allows replication of IESR • Portal harvests IESR records • Caches locally for use by portal software, e.g.: • Local service registry • Knowledgebase after conversion to appropriate format • Scenario: portal for Open Access material in Institutional Repositories ELPUB2006

  17. Distributed Service Registries • Scope of IESR • JISC, UK, international? • Scalability and Data ownership issues • Distributed / federated model • Each node describes own resources • How to cross search? • Metasearch; UDDI; OAI-PMH harvest • IESR collaboration with OCKHAM in US • Replication by OAI-PMH; search local ELPUB2006

  18. Sharing Descriptions • Sharing collection descriptions • Created by resource provider • Need common / derivable metadata schema • NISO Metasearch Initiative • OAI-PMH to share descriptions • OAI-PMH includes provenance and rights containers • Rights issues: common CC Licence? ELPUB2006

  19. IESR Future • More and updated content • New IESR services • Maintenance of metadata schema • Demonstrating viable IESR use • Collaboration with Service Registry development, UK and international • Persistence of content ELPUB2006
