5. 2006-01-18IESR Contributors Workshop5 IESR Identifiers Every entity has a URI Assigned on registration in IESR PURL-based Object Identifier (POI) Example: http://purl.org/poi/iesr.ac.uk/105636559-25788 Internal use: local part of identifier only

6. 2006-01-18IESR Contributors Workshop6 IESR Entity Description Described by metadata Based on open standards Metadata defined by Application Profile –Semantics –Occurrence –Searchable Data Supply as separate entities

7. 2006-01-18IESR Contributors Workshop7 IESR Collection Metadata Based on RSLP Collection Description Simplification for electronic resources Consistent with: –DCMI Collection Description Application Profile –NISO MI Collection Description Links to other entities: –hasService: Service (IESR id) –Owner: Agent (IESR id)

8. 2006-01-18IESR Contributors Workshop8 Vocabulary Encoding Schemes Defined in Application Profile Single backbone subject scheme –Dewey Decimal Classification System Other common vocabularies supported iesr:usesControlledList –IESR defined list (extensible) –terminology service; item level search

10. 2006-01-18IESR Contributors Workshop10 IESR Service Metadata More than RSLP CD ‘locator’ Bespoke IESR scheme Single access method: –Z39.50, SOAP, OAI-PMH, Web/CGI Location URL Interface property for some service types using appropriate schema Links to other entities: Agent, Collection

11. 2006-01-18IESR Contributors Workshop11

12. 2006-01-18IESR Contributors Workshop12 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

13. 2006-01-18IESR Contributors Workshop13 Agent Metadata Agent name Agent description Contact details, address, URL Links to other entities: –owns: Collection –administers: Service

14. 2006-01-18IESR Contributors Workshop14 IESR Administrative Metadata Included with every entity Data suppliers can include: –Internal: creator/contributor, creation dates –External: source External: IESR includes: –creating organisation, publisher (IESR) –latest modification date –rights to reuse descriptions

16. 2006-01-18IESR Contributors Workshop16 IESR Services Details on IESR web site Z39.50 –Search via Bib-1 attributes –Results: text (SUTRS); XML OAI-PMH for harvesting OpenURL Link-To Resolver –Implements IESR identifier resolution Web Search and Browse Data supply Editor

17. 2006-01-18IESR Contributors Workshop17 Future Services Web Services SOAP / SRW (planned) RSS UDDI (under investigation) –Prototype registry –Mapping IESR data to UDDI –Is there a requirement? Data ingest / harvest

18. 2006-01-18IESR Contributors Workshop18 IESR XML Composite Collection record via Z39.50: –Collection –All services that provide access –All agents: Owners of collection Administrators of services Single entity record via OAI-PMH Simple Dublin Core for Interoperability

19. 2006-01-18IESR Contributors Workshop19 Portal in JISC IE JISC defines a portal: A network service that brings together content from diverse distributed resources using technologies such as cross searching, harvesting, and alerting, and collates this into an amalgamated form for presentation to an end user.

20. 2006-01-18IESR Contributors Workshop20 Using IESR Portal –amalgamated set of resources IESR provides: –Discovery of resource collections –Up-to-date details of access to collections Using IESR Portal builder can: –Add new services to portal –Provide metasearch

21. 2006-01-18IESR Contributors Workshop21 Portal Metasearch Scenario Social Science portal discovers collections with e.g. Z39.50 services Provides cross-search to end-user using e.g. Z39.50 Portal builder doesn’t need to know about all resources Users discover collections unaware of

22. 2006-01-18IESR Contributors Workshop22 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 –Conversion into local configuration file

23. 2006-01-18IESR Contributors Workshop23 MIMAS Metadatabase Use Scenario MIMAS Metadatabase is a catalogue of resources provided by MIMAS Metadatabase will –Harvest changed IESR records nightly –Select MIMAS records –Update Metadatabase Staff have only one set of descriptions to maintain XML descriptions for other uses

24. 2006-01-18IESR Contributors Workshop24 Use by Portal Builder Discover resource and access details by Web interface Handcraft resource into metasearch Possible future Digital Library build software will automate process SOAP services need manual intervention

25. 2006-01-18IESR Contributors Workshop25 Other Uses Portal Links to Web Search –General resource discovery Reuse collection description –Initially created by resource supplier –Shared by multiple registries and applications RSS Aggregator (news; data alerts) –Personal digital library portal

26. 2006-01-18IESR Contributors Workshop26 Metadata Schema Use OCKHAM (US): Outcomes of NSF projects CETIS / DEST: eLearning/Admin in Australia Standards development: –DCMI Collection Description –NISO Metasearch Initiative –DCMI Agents Working Group Stakeholder requirements: –Institution details –eLearning

27. 2006-01-18IESR Contributors Workshop27 Wider Information Environment Scope of IESR –JISC, UK, international? –Data ownership and maintenance Distributed / federated model –Each node describes own resources –How to cross search? IESR collaboration with OCKHAM in US Sharing collection descriptions –Need common metadata schema

28. 2006-01-18IESR Contributors Workshop28 IESR Future More and updated content New IESR services Demonstrating viable IESR use Persistence of content Maintenance of metadata schema International interest in Service Registries
