IMPORTANT: This page refers to features that were added in VuFind 1.1. If you are using an earlier version, you will have to upgrade.

This page contains details on writing a custom driver for an OpenURL Link Resolver not already supported by VuFind.

Note that Link Resolver Drivers are only used when the “embed” setting is turned on in the [OpenURL] section of web/conf/config.ini. This setting allows link resolver results to be directly embedded in the VuFind search page rather than opening in a separate window.

• Link Resolver Drivers are found in the web/sys/Resolver folder of the VuFind installation.
• The PHP file containing the driver must be named for the value used as the resolver setting in the [OpenURL] section of web/conf/config.ini. (i.e. “sfx.php”).
• The name of the class defined in the PHP file should be the resolver setting, capitalized and prefixed with “Resolver_”. (i.e. “Resolver_360link” or “Resolver_Sfx”).
• The class must implement the ResolverInterface (found in web/sys/Resolver/Interface.php).

This method takes an OpenURL as a parameter and retrieves details from the link resolver.

This method takes the output of fetchLinks and parses it into an associative array with the following keys:

• href - the link to access the resource
• title - a text description of the resource
• coverage - coverage range applicable to the resource
• service_type - used to categorize links (getHolding = local print holding, getWebService = special service related to item, getDOI = DOI link, getFullTxt = electronic holding)
