Outline
• Purpose of JISC Information Environment Service Registry (IESR)
• IESR content description• IESR services• Using IESR for metasearch• Future direction of service registries• Integration Issues

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

IESR Content
• Descriptions of:– Collections of resources– Informational Services that provide access– Agents: Owners / Administrators– Transactional Services
• Supplied by resource providers• Check by IESR content manager

IESR Entity Description
• Entities identified with URI• Described by metadata• Metadata defined by Application Profile
– Semantics– Occurrence– Searchable
![Page 7: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/7.jpg)

IESR Collection Metadata
• Based on RSLP Collection Description• Simplification for electronic resources• Consistent with:
– DCMI Collection Description Application Profile
– NISO MI Collection Description
• Vocabularies for property values

IESR Service Metadata
• More than RSLP CD ‘locator’• Bespoke IESR scheme 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

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

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

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 Supply Editor
![Page 14: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/14.jpg)
2006-03-03 SRU Integration Workshop 14
Future Services
• SRU• Web Services SOAP / SRW (planned)• RSS• UDDI (under investigation)
– Mapping IESR data to UDDI– Prototype registry

Using IESR: Portal Metasearch
• Social Science portal discovers collections with e.g. SRU services
• Provides cross-search to end-user using e.g. SRU
• Portal builder doesn’t need to know about all resources
• Users discover collections unaware of• Alternative: OAI-PMH harvest
![Page 16: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/16.jpg)
2006-03-03 SRU Integration Workshop 16
Distributed Service Registries
• Scope of IESR• Distributed / federated model
– Each node describes own resources
• How to cross search?– Metasearch; UDDI; OAI-PMH harvest
• IESR collaboration with OCKHAM in US– Searching is local– Replication by OAI-PMH harvest
![Page 17: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/17.jpg)
2006-03-03 SRU Integration Workshop 17
Integration Issues
• Resources have Web interface only• IESR covers all service protocols:
– Few SRU services in JISC IE
• Contributing technical service details• Use of Service Registry still visionary• Dynamic use with SOAP not feasible
– NISO Web Services and Practice WG– SRW
• Description of authentication details
![Page 18: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/18.jpg)
2006-03-03 SRU Integration Workshop 18
Integration Issues: Sharing
• Sharing records needs common schema– NISO Metasearch Initiative Collection
Description: basis of IESR and OCKHAM
• Rights issues– Simplified with common CC licence
• Cross searching federated registries:– Metasearch? Harvest?
• UDDI– Loss of full collection description
![Page 19: IESR: A Registry of Collections and Services](https://reader034.fdocuments.net/reader034/viewer/2022051821/56815881550346895dc5e3e1/html5/thumbnails/19.jpg)
2006-03-03 SRU Integration Workshop 19
Recommendations
• Encourage the provision of m2m interfaces for resources– Advertise SRU as low barrier solution
• Register SRU services in online directories to encourage use
