The Flow of an SFX Request SOURCE OpenURLSFX Server + SFX Database TARGET TARGET URL created by SFX server.

 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 Sources

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

 Developed by Herbert Van de Sompel and Ex Libris and submitted to NISO December 2000  NISO Committee AX formed; started work in June 2001 …  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: OpenURL Status

&volume=12&issue=3&spage=1&epage=8&date=1998 &aulast=Smith&aufirst=Paul OpenURL (the enabling mechanism)

 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 OpenURL function

Identify a user that has access to a service component; and OpenURL awareness1 2 Provide an OpenURL for each metadata-object, e.g. a brief citation, reference in journal article, etc.

 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 …? Recognizing Users

 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: &volume=12&issue=3&spage=1&epage=8&date=1998&aulast =Smith&aufirst=Paul OpenURL format

 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 Fetch

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

 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: atitle=Developmental%20Expression%20of%20Amylases%20During%20Barley%20Malting& amp;issn= &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 … GenericRequestObject
