Background and functionality
![Page 5: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/5.jpg)
Origins of the OpenURL
• the context– distributed information environment (JISC IE)– multiple A&I and other discovery services– rapidly growing e-journal collection– need to interlink available resources
• the problem– links controlled by external info services– links not sensitive to user’s context (appropriate copy
problem)– links dependent on vendor agreements– links don’t cover complete collection
![Page 6: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/6.jpg)
The problem
• the context– distributed information environment– multiple A&I and other discovery services– rapidly growing e-journal collection– need to interlink available resources
• the REAL problem– libraries have no say in linking– libraries losing core part of ‘organising information’
task– expensive collection not used optimally– users not well served
![Page 7: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/7.jpg)
The solution…
• do NOT hardwire a link to a single service on the referenced item (e.g. a link from an A&I service to the corresponding full-text)
• BUT rather– provide a link that transports metadata
about the referenced item– to another service that is better placed to
provide service links

Brief history of the OpenURL
• ~1998 – nature of solution determined• ~1999 – first real experiments (Ghent, LANL,
Wiley, SilverPlatter, Ex Libris, arXiv, …)• ~2000 – OpenURL 0.1 released, adoption by
community, SFX beta released• ~2001 – integration of OpenURL and
DOI/CrossRef frameworks, first non-SFX resolvers appear
• proposal to standardise OpenURL framework thru NISO…

Summary (2)
• OpenURL source– a service that embeds OpenURLs into its user-
interface in order to enable linking to most appropriate copy
• OpenURL resolver– a service that links to appropriate copy(ies) and other
value added services based on metadata in OpenURL
• OpenURL target– a service that can be linked to from an OpenURL
resolver using metadata in OpenURL

Current and future status

OpenURL status in UK
• OpenURLs currently in use in some form at– Bradford, EDINA, Edinburgh, UEA, Derby, Bath,
Bangor, MIMAS, Royal Holloway, Westminster, Swansea, …
• OpenURL technology available from several vendors– Ex Libris (SFX), Openly Informatics (1Cate), Endeavor
(LinkFinderPlus), FD (OL2)
• open source solutions– ZBLSA

Standardisation
• all current OpenURL deployment is based on OpenURL version 0.1
• NISO currently standardising version 1.0
• expect to see gradual transition over next 12-24 months or so towards greater use of version 1.0
• …

NISO OpenURL version 1.0
• retains notion of transporting metadata to obtain context-sensitive services
• more flexible framework (metadata, syntax and transport)
• version 0.1 limited to bibliograph resources
• version 1.0 extensible to other communities (e.g. eLearning)

Issues
![Page 31: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/31.jpg)
Issues for ‘resolvers’
• selecting OpenURL resolver software– hosted vs. in-house?– same vendor as library system or not?
• maintaining OpenURL resolver configuration tables (knowledge base)– this is where bulk of your effort is required– ideally need to include details of all physical and
electronic holdings– may buy-in some of the information from 3rd-party
supplier (e.g. serialsolutions.com) based on knowledge of subscriptions
![Page 32: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/32.jpg)
Issues for ‘sources’
• remember… you’ll probably want to make your OPAC an ‘OpenURL source’
• in general, need to maintain knowledge of end-user’s prefered OpenURL resolver…
• … but in the case of an institutional OPAC, can probably hardwire the same resolver for everyone?
![Page 33: UKOLN is supported by: An overview of the OpenURL UKOLN/JIBS OpenURL Meeting London, September 2003 Andy Powell, UKOLN, University of Bath a.powell@ukoln.ac.uk.](https://reader035.fdocuments.net/reader035/viewer/2022062619/551609fc550346a2308b5005/html5/thumbnails/33.jpg)
Issues for ‘targets’
• remember… you’ll probably want to make your OPAC an OpenURL target
• need to identify mechanism for deep-linking into ‘target’ service from OpenURL resolver– e.g. does ‘target’ support URLs based on
ISBNs or ISSNs?
• need to disclose this mechanism to resolvers (but no standard way to do this yet)
