4. 2006-03-23NSF Digital Library Service Registries workshop4 Current digital landscape "…a vast and sometimes bewildering range of potential sources of electronic information. Little wonder, then, that many users remain unaware of their existence or fail to discover their value for their own learning, teaching or research."

5. 2006-03-23NSF Digital Library Service Registries workshop5 JISC Information Environment "…aims to offer the user a more seamless and less complex journey to relevant information and learning resources" "…will enable presentation, delivery and use of online resources in ways tailored to support individual and institutional requirements in learning, teaching and research" Information Environment: Development Strategy [c.2003] http://www.jisc.ac.uk/index.cfm?name=strat_ieds0105_draft2

9. 2006-03-23NSF Digital Library Service Registries workshop9 Information Environment Service Registry A catalogue of the electronic resources available within the JISC’s Information Environment Contains information about: –the resources themselves –how to access the resources –the resource provider(s) Is accessible by other applications via machine-to-machine interfaces

10. 2006-03-23NSF Digital Library Service Registries workshop10 Project history Partners –MIMAS, University of Manchester –UKOLN, University of Bath –Cheshire Development Team, University of Liverpool Funded by JISC in three phases since November 2002 Current phase started 1 March 2005

11. 2006-03-23NSF Digital Library Service Registries workshop11 Current contents 257 electronic resources currently described, supplied by JISC-funded service providers 313 services registered, 162 agents We will be expanding our content to encompass non-JISC service providers: e.g. –institutional resources (digital repositories, OPACs) –resources of other UK Common Information Environment partners (National Archives, British Library, National Health Service, BBC)

12. 2006-03-23NSF Digital Library Service Registries workshop12 IESR for service providers Provides information about resources based on existing descriptive standards –A 'master description' –Can be re-used in a variety of contexts Advertises resources –Should lead to increased use

13. 2006-03-23NSF Digital Library Service Registries workshop13 Issues Defining the scope of the IESR Embedding the IESR into the JISC IE Encouraging contributors to describe their resources: demonstrating benefit Ensuring quality and currency of metadata Keeping pace with changing/emerging technical standards Working with developers of applications that will make use of IESR: demonstrate value

15. 2006-03-23NSF Digital Library Service Registries workshop15 Outline JISC Information Environment Service Registry (IESR): IESR content description IESR services Using IESR The future

16. 2006-03-23NSF Digital Library Service Registries workshop16 IESR Content Descriptions of: –Collections of resources –Made available via Informational Services –Agents: Owners / Administrators –Transactional Services Service: a system that provides one or more functions to a consumer Contributed by resource providers QA check by IESR content manager

17. 2006-03-23NSF Digital Library Service Registries workshop17 IESR Entities Collection ServiceAgent administers owns provides access

18. 2006-03-23NSF Digital Library Service Registries workshop18 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

19. 2006-03-23NSF Digital Library Service Registries workshop19 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

21. 2006-03-23NSF Digital Library Service Registries workshop21 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 Prototype service type list, e.g. Alert Interface property for some service types using appropriate schema

22. 2006-03-23NSF Digital Library Service Registries workshop22

23. 2006-03-23NSF Digital Library Service Registries workshop23 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

24. 2006-03-23NSF Digital Library Service Registries workshop24 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

25. 2006-03-23NSF Digital Library Service Registries workshop25 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 Editor for Contributors

26. 2006-03-23NSF Digital Library Service Registries workshop26 Use of IESR services, 2005-2006

27. 2006-03-23NSF Digital Library Service Registries workshop27 Future Services SRU (NISO MI MXG) Web Services SOAP / SRW (planned) RSS Data ingest by harvest UDDI (under investigation) –Mapping IESR data to UDDI –Prototype registry –Is there a requirement?

28. 2006-03-23NSF Digital Library Service Registries workshop28 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

29. 2006-03-23NSF Digital Library Service Registries workshop29 Portal Metasearch Scenario Social Science portal discovers collections with e.g. Z39.50 services Provides cross-search to end-user Portal builder doesn’t need to know about all resources Users discover collections unaware of Alternative: OAI-PMH harvest Static use by Portal builder: –Necessary for SOAP

30. 2006-03-23NSF Digital Library Service Registries workshop30 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; –Aggregate by OAI-PMH harvest Rights issues: common CC Licence?

31. 2006-03-23NSF Digital Library Service Registries workshop31 Standard Metadata Schema Sharing collection descriptions –Created by resource provider –Need common / derivable metadata schema NISO Metasearch Initiative / DCMI Collection Description –Provides a common core IESR a practical example application –Feedback to NISO MI and DCMI CD

32. 2006-03-23NSF Digital Library Service Registries workshop32 IESR Future More and updated content New IESR services Maintenance of metadata schema –Use by: OCKHAM; DEST Demonstrating viable IESR use Persistence of content
