Using the Enhanced OpenURL Framework: Upgrading from Version 0.1 to 1.0 Ann Apps MIMAS, University of Manchester, UK
Using the OpenURL Framework • Support for scholarly information community • Upgrade from v0.1 • Practical use of OpenURL within a scholarly information application • Conformance requirements NISO OpenURL Workshop
The OpenURL Framework for Context-Sensitive Services • Generalisation and formalisation of v0.1 • ContextObject: referenced resource and associated resources in context of reference • OpenURL: method of transporting ContextObject NISO OpenURL Workshop
ContextObject Example • In e-journal application Elsevier ScienceDirect, Ann Apps at Manchester University finds • McArthur, JG “p27-p16 Chimera…” Molecular Therapy 3(1) 8-13 • References • Bergelson, J. “Isolation of…” Science (275) 1320-1323 • ContextObject contains 6 entities: • Referent: Bergelson paper • ReferringEntity: McArthur paper; Referrer: ScienceDirect • Requester: ann.apps@man.ac.uk; ServiceType: full text • Resolver: http://sfx.mimas.ac.uk/sfxmanx NISO OpenURL Workshop
Describing Entities • Descriptors • Identifier: info:doi/10.1126/science.275.5304.1320 • Metadata • By-value • By-reference • Formats • Key / Encoded Value (KEV) • XML NISO OpenURL Workshop
Using ContextObjects • Transports • Flavours of OpenURL (by-value, by-reference, inline) • Community Profiles • San Antonio Profiles Level 1 and 2 for scholarly information • Dublin Core Profile • Core components in OpenURL Registry NISO OpenURL Workshop
San Antonio Profile Level 1 • Key/Encoded Value • Namespaces: • URI/URN, eg. http, mailto, ISSN, ISBN • info, eg. DOI, PubMed Id, SICI • Metadata Formats: • journal, book, patent, dissertation • Service Types: • abstract, citation, full text, holdings, ILL NISO OpenURL Workshop
zetoc • Current awareness and document delivery service for journal articles and conference papers in every imaginable subject • Based on British Library’s Electronic Table of Contents • Available to researchers and learners in UK Higher and Further Education; England and Scotland National Health Service NISO OpenURL Workshop
Using zetoc • Search via Web interface • Email alert • zetoc full record provides citation details • Article can be ordered from BL or by ILL • Users want electronic full text of article if they have valid subscription NISO OpenURL Workshop
Default Location • OpenURL link to MDL LitLink • Not an appropriate copy but many have access to major resources • “It’s worth a try but access can’t be guaranteed” • OpenURL linking well used and no complaints NISO OpenURL Workshop
zetoc OpenURL v0.1 • Translate citation metadata into a URL link http://sfx.mimas.ac.uk/sfxmanx? sid=mimas:zetoc &genre=article &atitle=Phase compositions… &title=Scripta Materialia&issn=1359-6462 &aulast=Apps&auinit=P.J.&date=2003 &volume=48&issue=5&spage=475&epage=481 NISO OpenURL Workshop
OpenURL v1.0 url_ver=Z39.88-2003 &url_ctx_fmt=info:ofi/fmt:kev:mtx:ctx &rfr_id=info:ofi/rfr:db:mimas.ac.uk:zetoc &rft_val_fmt=info:ofi/fmt:kev:mtx:journal &rft.genre=article &rft.atitle=Phase compositions… &rft.jtitle=Scripta Materialia&rft.issn=1359-6462 &rft.aulast=Apps&rft.auinit=P.J.&rft.date=2003 &rft.volume=48&rft.issue=5&rft.spage=475&rft.epage=48 NISO OpenURL Workshop
Upgrade v0.1 to v1.0 • San Antonio Profile Level 1 (KEV) and Inline OpenURL • Add url_ver key • Add url_ctx_fmt key to indicate KEV • Change sid to rfr_id and use rfr:db: scheme • Add rft_val_fmt: referent by-value journal metadata • Prefix metadata keys by rft. • jtitle preferred for journal title • Change id to rft_id with info:, eg info:doi/10... NISO OpenURL Workshop
Entities and Descriptors in OpenURL v0.1 • Referent: referenced article • Referrer: origin description (sid) • Resolver: base URL (link server) • Requester, ReferringEntity, ServiceType: • in local identifier zone with private identifier (pid) • Identifier descriptor: global identifier (4) • Metadata Format: object metadata (journals / conferences) NISO OpenURL Workshop
Hybrid OpenURLs • Upgrade transition period • Problem for Referrers • Solution: create hybrid OpenURLs • Combined v1.0 and v0.1 • Resolvers expected to deal gracefully with foreign keys NISO OpenURL Workshop
Hybrid OpenURL http://sfx.mimas.ac.uk/sfxmanx? url_ver=Z39.88-2003&url_ctx_fmt=info:ofi/fmt:kev:mtx:ctx &rfr_id=info:ofi/rfr:db:mimas.ac.uk:zetoc&sid=mimas:zetoc &rft_val_fmt=info:ofi/fmt:kev:mtx:journal &rft.genre=article&genre=article &rft.atitle=Phase compositions… &atitle=Phase compositions… &rft.jtitle=Scripta Materialia &title=Scripta Materialia ... NISO OpenURL Workshop
OpenURL Trial • Draft standard for trial use • Trial April - November 2003 • Sources, Resolvers, End-users • zetoc: source SAP1 KEV inline OpenURLs • Tested with several resolvers NISO OpenURL Workshop
Other Example Scenarios Examples listed in SAP1 Implementation Guidelines • Inline, by-value, by-reference OpenURL • Article referenced from electronic journal article in e-journal service • Conference paper referenced from e-journal article, or A+I service • Book referenced from a book, or shopping service • Journal referenced from serials directory NISO OpenURL Workshop
SAP1 Source OpenURLs • Provided by Referrers, eg. e-journals, A+I services, library OPACS • Provide as much information as available • Provide a Referrer Identifier • Defines provenance of data • Service type requests are guideline only • Private data discouraged NISO OpenURL Workshop
SAP1 Resolver Conformance • Target of activated OpenURL source link • Support all selections from Registry defined as part of SAP1 • Resolver behaviour not prescribed • Handle gracefully: • Namespaces and metadata formats cannot resolve • Foreign keys • Continue to accept v0.1 OpenURLs NISO OpenURL Workshop
Beyond San Antonio • OpenURL already well used in scholarly information environment • Potential to provide intelligent ‘appropriate copy links’ • OpenURL Framework very general. Potential for use in diverse domains with new Profiles NISO OpenURL Workshop
