ELPUB20062 Outline Purpose of JISC Information Environment Service Registry (IESR) IESR content description IESR services Using IESR The future
ELPUB20063 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
ELPUB20064 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
ELPUB20065 IESR Entities Collection ServiceAgent administers owns provides access
ELPUB20066 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
ELPUB20067 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

ELPUB 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
ELPUB 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
ELPUB 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
ELPUB 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
ELPUB 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
ELPUB 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
ELPUB 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?
ELPUB 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
