Hyperlinks with Dynamic Content from the Coverage Database (Secondary Lookups)

Some OpenURLS do not contain information, such as journal title, that you want to display in a hyperlink. You can load this content into the coverage database and retrieve it with a "secondary lookup." A secondary lookup means that when the WebBridge resolution server generates the hyperlink, the server includes data that exists only in the coverage database (secondary data) as well as meta tag data from the OpenURL (primary data).

For example, some resource vendors include an ISSN in the OpenURL but do not include a journal title. If these journal titles are loaded into the coverage database, the WebBridge resolution server can retrieve the journal title in a secondary lookup and use it as dynamic content in the hyperlink.

To use dynamic content from the coverage database in a hyperlink, you must:

1. Determine the dynamic content to include in the hyperlink.
2. Construct the hyperlink with field selectors representing the dynamic content from the OpenURL and coverage database column names.

   NOTE

   Do not use coverage database column names for columns containing proprietary information in hyperlink secondary lookups, as hyperlinks directly display to users.

   Coverage database column names for columns containing proprietary information are used in target resource URL secondary lookups.

3. Enter the hyperlink in the Link Display text box in the Resolution Server Linking section of the appropriate resource definition.

   NOTE

   To use secondary lookups, you must use a match data test and choose an option in the Match against this resource drop-down menu of the resource definition.

For example, to create a hyperlink that takes the ISSN meta tag from an OpenURL and the TITLE from the coverage database and incorporates them into a hyperlink, enter:

Search for $#@ISSN##@TITLE#$ at #LinkText#

In this example, if a user at an external origin requests resources, and an appropriate resource is an article that your library offers through ProQuest, the system:

• replaces #@ISSN# with the content of the OpenURL field ISSN
• replaces #@TITLE# with the content of the TITLE field in the coverage database
• replaces #LinkText# with "ProQuest"
• displays the hyperlink to the user at the external origin
  
  The hyperlink displayed to the user might read, for example:
