  3. Targets and Target Services • Where a user “lands” • Services are the “facilities”: • A ‘getAuthor’ service would run a search on an author’s name • A ‘getFullTxt’ service would link to the full text of a particular article from a Target publisher • A ‘getHolding’ service would link to a record in a library catalog • Targets must have a link-to syntax that supports the Service • The Target table contains information on services into which linking is possible, e.g. full text repositories, OPACs, citation databases, or Internet search engines.

  4. TARGETS EBSCO A.S.P. provides: getFullTxt, getTOC Library Catalog provides: getHolding JSTOR A&S I provides: getFullTxt Oxford U. Press provides: getFullTxt, getAbstract WWW Search Engines provides: getWebSearch RefWorks provides: getReference Service links between Sources and Targets SOURCES CSA requests: getFullTxt getTOC getHolding getDocumentDelivery getAbstract getWebSearch getReference getCitedJournal etc… Source Services link to Target Services = conceptual links that will be presented in SFX Menu if certain requirements (Thresholds) are met ….

  5. Database Tables SOURCE TARGET OBJECT SOURCESERVICE TARGETSERVICE OBJECT PORTFOLIO

  6. Object Portfolios • A 'hook' … where OBJECTS and TARGET SERVICES meet • Generally held to represent sets of journals from particular publishers • Contain: • ISSN • Date threshold information • PARSE_PARAM (jkey) information, if necessary for linking • Global Object Portfolios provided by Ex Libris as part of the KnowledgeBase; localized by customers … must be activated!

  7. Target Parsers • Programs used by SFX to link to Targets; which one to use is indicated in Target Service "parser" field • Use information from: • GenericRequestObject • Original OpenURL sent by Source • Fetch operation (if any performed) • SFX metadata augmentation • PARSE_PARAM field in TARGET SERVICE and OBJECT PORTFOLIO tables, as appropriate • Provided by Ex Libris; symbolically linked to sfx_global instance

  8. PARSE_PARAMS and Target Parsers • In the TARGET SERVICE table: parameters that apply to the whole Target Service ->syntax: url=base_URL_of_Target (include http:// !) • In the OBJECT PORTFOLIO table: parameters that apply to one particular Object Portfolio ->syntax: jkey=fill_in_your_jkey

  16. Putting a Proxy into the Picture SFX Server Source OpenURL + SFX Database • To set this up, you must: • Set up the proxy setting under ‘Menu Configuration’ in the Admin Center • Check off the ‘proxy’ box in the KB P R O X Y … http://ezproxy.lib.university.edu:2048/ login?url=http://www.sciencedirect.com /science/journal/03064603

  17. Shortcomings: • Centralized resolution does not address “appropriate copy” problem: • Full text from aggregator service • Full text held locally • Print copy available • No option for alternative services DOI Linking

  18. DOI link DOI Server OpenURL Aware Server DOI Metadata SFX Compliments DOIs/CrossRef: • Local SFX servers improve services for DOI links OpenURL

  19. Server Metadata DOI DOIs/CrossRef compliment SFX: • Article-level DOIs improve Target • link-to syntaxes DOI link
