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 … 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

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 awareness
11
22 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

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: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>
