  1. The OpenURL SFX Training Ex Libris (USA) Inc.

  2. The Flow of an SFX Request OpenURL SFX Server SOURCE + SFX Database TARGETURL created by SFX server. TARGET

  3. Sources • Where a user is coming from, beginning a search • Examples: • OPAC • A&I database • Online journal • E-print archives (OAi) • Electronic Theses and Dissertations (ETD) • Your local data repositories • All sources must provide an OpenURL http://www.sfxit.com/sources.html

  4. OpenURL (the enabling mechanism) • OpenURL make metadata available to service componentdynamically inserted • linking server describes context of user • OpenURL A&I OpenURL OpenURL OpenURL Link Server e-print OPAC OpenURL Full Text

  5. OpenURL Status • Developed by Herbert Van de Sompel and Ex Libris and submitted to NISO December 2000 • NISO Committee AX formed; started work in June 2001 … http://library.caltech.edu/openurl • Fast track work item … Version 1.0 testing phase started 1 May 2003 • Low-barrier for implementation by Information Providers • OpenURL draft syntax adopted as Version 0.1 • List of OpenURL adopters: http://www.sfxit.com/sources.html

  6. OpenURL (the enabling mechanism) http://sfx.aaa.edu/menu?genre=article&issn=1234-5678 &volume=12&issue=3&spage=1&epage=8&date=1998 &aulast=Smith&aufirst=Paul

  7. OpenURL function • Enables transfer of metadata … • from an information resource • to a service component (SFX server) that can determine and provide context-sensitive services for the metadata

  8. OpenURL awareness Identify a user that has access to a service component; and 1 Provide an OpenURL for each metadata-object, e.g. a brief citation, reference in journal article, etc. 2

  9. Recognizing Users • Information Providers need to know which BASE_URL to insert into OpenURLs … in order to provide correct/local SFX services … • User Profiles • IP address identification • CookiePusher mechanism • Digital Certificates …?

  10. OpenURL format • BASE_URL: • Server address for the service component (SFX) • Content: • Elements of the metadata or pointer to metadata in a public syntax • Information supporting delivery of services • Example: • http://sfx.aaa.edu/menu?genre=article&issn=1234-5678 • &volume=12&issue=3&spage=1&epage=8&date=1998&aulast=Smith&aufirst=Paul

  12. OpenURL examples http://sfx.caltech.edu:8888/caltech?sid=Caltech:WOS&genre=article&issn=0305-4470&volume=33&issue=35&spage=L331&epage=L337&date=2000&part=&title=JOURNAL+OF+PHYSICS+A-MATHEMATICAL+AND+GENERAL&aulast=Aratyn&auinit=H&atitle=The+complex+sine-Gordon+equation+as+a+symmetry+flow+of+the+AKNS+hierarchy&pid=%3Cauthors%3EAratyn%20H%7CFerreira%20LA%7CGomes%20JF%7CZimerman%20AH%3C/authors%3E http://sfxserver.somewhere.edu/sfx_local?sid=dbvendor:name&pid=myid:178912781 http://demo.exlibrisgroup.com:9003/demo?id=doi:10.1034/j.1399-0039.2000.560502.x

  13. Fetch • Optional • A way to retrieve additional metadata about a digital object, beyond what comes on an OpenURL • Additional author names • Data specific to the database, such as patent id or dissertation number • Perhaps easier for Information Providers to implement quickly • Fetch syntaxes: Z39.50 and HTTP

  14. SFX Link Server • Accepts OpenURL as input from Information Provider • Analyzes contents of OpenURL • Evaluates appropriate Services based on metadata • (SFX Menu is shown to User) • Dynamically computes links to Target Services

  15. GenericRequestObject • A ‘metadata container’ resulting from SFX analysis of OpenURL • Used by SFX to evaluate and create Services • Contents can be checked in HTML source of SFX Menu and in /logs/sfxmenu.log file • Example: this OpenURL: http://demo.exlibrisgroup.com:9003/demo?sid=sfxit&genre=article& atitle=Developmental%20Expression%20of%20Amylases%20During%20Barley%20Malting&issn=0733-5210&date=2001&volume=33&issue=3&spage=279&aulast=Georg-Kraemer&auinit=JE&pid=<authors>Mundstock,EC|Cavalli-Molina,S</authors> corresponds to this GenericRequestObject …
