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: Contributed by resource providers
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

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

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 IESR provides:
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
