Sources
• Where a user is coming from, beginning a search
• Examples:• A&I database• OPAC• E-journal articles
• Sources must be OpenURL-enabled!• The SFX SOURCE table contains
information about information resources that can be the starting point of a link
OpenURL Format
• BASE URL:• Server address for the SFX link server
• CONTENT:• Elements of the metadata or pointer to
metadata in 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=2003&aulast=Klein&aufirst=Calvin&pid=<ED>1234567</ED>

Sending OpenURLs to YOUR SFX server• Know your BASE URL:
• Server address for the SFX link server• Button options
• Contact your Source vendors (CSA, FirstSearch, etc.) and ask them how to "turn on" OpenURLs for your end users• Use SFX Source Configuration document• Ask for a test account, if available
• When you turn on OpenURLs for your production accounts, end users will see SFX buttons and can link to your SFX server (so be ready!)
Some vendors have an Admin section:
TARGETSEBSCO 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

• SFX scripts identify which source configuration files and Source Parser and SOURCE table entry to use in the following way:
OpenURL 'sid' source_v0_1.dir_ or source_v1_0.dir_ [depending on version of OpenURL sent]
.config files SOURCE entry in SFX KB Source Parser (if any needed)
Source.dir – a file central to operation
1. Metadata is transported to the SFX server via the OpenURL. The 'sid' of an OpenURL contains information about the identity of the source database; example:http://sfxserver.somewhere/sfx_local?sid=SilverPlatter:MX&pid=myid:1234567
2. The value of this 'sid' is used for a lookup in a local file called 'source.dir'
3. For each Source, the source.dir contains the identification of a configuration file
4. The configuration files contain information about:• The name of the SOURCE entry in the SFX database• The location and name of any Source Parser needed to
interpret the OpenURL5. MOST Sources need no additional local configuration. In
V3, source.dir is globally linked and will be updated each month by Ex Libris. It includes a file source_local.dir, where any necessary local configurations may be stored.
