  1. IESR, the JISC IE and beyond Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk Using the IESR: what’s in it for you? UKOLN is supported by: www.bath.ac.uk www.ukoln.ac.uk a centre of expertise in digital information management

  2. Contents • the changing environment • distributing the IESR • issues • conclusions Using the IESR: what's in it for you? - Jan 2005

  3. JISC IE • set the original scope of the IESR • to describe collections and services in the JISC IE • but what does in mean? • e.g. are the Nature and ingenta RSS feeds in or out? Using the IESR: what's in it for you? - Jan 2005

  4. Glasgow Edinburgh Newcastle Belfast Manchester DL Cambridge Oxford Hinxton Cardiff RAL London Southampton Grid/eScience • the Grid Engineering Task Force is currently building a networkof ‘service registries’ • one per eScienceCentre • based on UDDI • jUDDI (Java-basedsoftware platform) • focus on ‘services’rather than‘collections’? Using the IESR: what's in it for you? - Jan 2005

  5. NISO Metasearch • (see Pete Johnston’s presentation) • ‘library portal’ vendors often already offer and maintain a ‘service registry’ in the form of a configuration database or ‘knowledge base’ • part of the package – i.e. you’ve already paid for it! • what is the vendor view of the IESR • a useful source of info? • a chance to off-load a maintenance headache? • a competing product in the market-place? Using the IESR: what's in it for you? - Jan 2005

  6. Web services/eCommerce • integration of Web services in eBusiness/eCommerce sector seems to be the main driving force behind UDDI • but… public registries at www.uddi.org still completely unusable • perception that UDDI spec is highly complex • tool availability largely limited to Java • note that simpler use of WSDL (e.g. see www.xmethods.com) is more successful Using the IESR: what's in it for you? - Jan 2005

  7. ELF and VRE • the JISC E-Learning Framework and Virtual Research Environments • attempts to develop service-oriented approach (SOA) to learning management systems and research tools • break monolithic systems into smaller service components • typically instantiated using SOAP or REST • potentially leading to big increase in number of services requiring registration Using the IESR: what's in it for you? - Jan 2005

  8. Portals and portlets • gradual increase in use of portal frameworks like uPortal for delivering institutional portals • integration of multiple ‘portlets’ within single personalised framework • many portlets delivered within the institution (i.e. intranet services) • in combination with internal ELF and VRE related activity leads to pressure to deliver ‘institutional’ (i.e. closed) service registry Using the IESR: what's in it for you? - Jan 2005

  9. Distributing the IESR • conclusion of all this is that the IESR cannot be seen as monolithic service • need to approach it more like the DNS than like Athens! • need to think about approaches for distributing the IESR across multiple (probably many!) players • UDDI • ‘digital library’ technologies like OAI-PMH • P2P approaches? Using the IESR: what's in it for you? - Jan 2005

  10. Re-using existing data • also need to take advantage of existing sources of ‘service’ and ‘collection’ descriptions • Z39.50 Explain • Z39.50/SRW ZeeRex • OAI-PMH ‘friends and neighbours’ Identify response • RSS channel lists using OPML (Outline Processor Markup Language) • i.e. need to populate service registries with existing work whenever possible - rather than causing new work Using the IESR: what's in it for you? - Jan 2005

  11. Registry distribution UDDI UDDI EDINA SR UDDI Institutional SR Grid SR UDDI JISC IE SR ExLibris SR UDDI UDDI Pure UDDI… Using the IESR: what's in it for you? - Jan 2005

  12. Registry distribution (2) UDDI/OAI-PMH/SRW UDDI EDINA SR UDDI Institutional SR Grid SR UDDI JISC IE SR ExLibris SR UDDI/OAI-PMH/SRW/Z39.50 UDDI Hybrid UDDI… Using the IESR: what's in it for you? - Jan 2005

  13. Registry distribution (3) UDDI/OAI-PMH/SRW UDDI EDINA SR UDDI Institutional SR Grid SR OAI-PMH JISC IE SR ExLibris SR Hybrid ‘digitallibrary’… UDDI/OAI-PMH/SRW/Z39.50 UDDI Using the IESR: what's in it for you? - Jan 2005

  14. Other shared services • also need to think about the interfaces between a distributed SR and other ‘shared services’? • e.g. who answers the question ‘which services expose metadata that conforms to the UK LOM Core?’ • the IESR (which holds details about services)? • the IEMSR (which holds information about metadata usage)? • or some combination of both? If so how? • choreography of multiple services still an issue Using the IESR: what's in it for you? - Jan 2005

  15. Conclusion and issues • only one real conclusion… that the future must be distributed rather than centralised • but, if so, do issues of • ownership • workflow • terminology • quality assurance get harder or easier (I think they get easier!) Using the IESR: what's in it for you? - Jan 2005

  16. Questions… Using the IESR: what's in it for you? - Jan 2005
