Targets and Target Services • Where a user “lands” • Services are the “facilities”: • A ‘get. Author’ service would run a search on an author’s name • A ‘get. Full. Txt’ service would link to the full text of a particular article from a Target publisher • A ‘get. Holding’ 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. 3

Database Tables SOURCE TARGET SOURCE SERVICE TARGET SERVICE OBJECT PORTFOLIO 5

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 Knowledge. Base; localized by customers … must be activated! 6

Target Parsers • Programs used by SFX to link to Targets; which one to use is indicated in Target Service "parser" field • Use information from: • Generic. Request. Object • Original Open. URL 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 9
