2. The Flow of an SFX Request Source URL GenericRequest Object SFX KB Service 1 Service 2 SFX Menu Target Parser Key:1234-5678 thresholds checked OpenURL metadata "container" … …

3. SFX Database

4. Sources Where a user is coming from, beginning a search Examples: A&I database OPAC Online journal Sources must be OpenURL-enabled! Librarians work with Sources available in their own library environments; can decide what Services would be most desired by users

5. 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

6. TARGETS EBSCO A.S.P. provides: getFullTxt, getTOC Library Catalog provides: getHolding JSTOR A&S I provides: getFullTxt WWW Search Engines provides: getWebSearch RefWorks provides: getReference Oxford U. Press provides: getFullTxt, getAbstract 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 ….

7. Database Tables SOURCE SOURCE SERVICE TARGET SERVICE TARGET OBJECT PORTFOLIO OBJECT

8. Objects The OBJECT table stores objects and information about objects Title ISSN/E-ISSN CODEN Abbreviated titles (alternate) Object type Related objects (title or ISSN change) Three types of objects are defined in the SFX database: Journals Books Preprints

9. Object Portfolios The OBJECT PORTFOLIO tables stores information to connect TARGET SERVICES and OBJECTs For example, this table indicates which journals are available from the Cambridge University Press collection, or from JSTOR Arts & Sciences 1 collection

11. Object Lookup Object Lookup [ set at Target Service] YES Is used when objects need to be attached to a particular target service The Target Service will show up on the SFX Menu screen only if the information you start from is part of the Object Portfolio of that Target Service Is mainly used for getFullTxt Target Services NO Is used when no objects need to be attached to a particular target service The Target Service will show up on the SFX Menu screen, regardless of the object with which you start Is used for more general, “search- oriented” Target Services, such as getHolding or getWebSearch

13. Thresholds Rules or conditions set on database items; found on TARGETs, TARGET SERVICEs, or OBJECT PORTFOLIOs Used to fine-tune SFX services that appear on SFX Menu Data in SFX requests must match the rule in order for the item to appear on the SFX Menu Written as Perl statements; can use Boolean to stack them (AND, OR) Threshold Composer to help

15. Threshold Types Global thresholds Supplied by Ex Libris Used as default Active if no local thresholds are used Updated automatically Local thresholds Specified by the institution Reflect local conditions Override global thresholds Not changed during the update procedure

16. Thresholds Combining global and local thresholds: global threshold: $obj->parsedDate(">=",1994,26,1) local threshold: GLOBAL && $obj->need("Institute","eq","MEDICAL") result: $obj->parsedDate(">=",1994,26,1) && $obj->need("Institute","eq","MEDICAL")
