Field Selectors

Field selectors enable you to define which part of a record or search should be sent as part of the URL in the resource link.

Click Field Selectors in the left-hand sidebar.

Example Field Selectors are loaded initially, but you can edit or remove existing entries and create new entries as needed.

Name: this is used within URL construction and is the link text for the Resource. You will need to replace all spaces with an underline or hyphen.

Description: only seen by staff in the administrative interface, so this is a brief note to clarify the name.

Example: Title from subfield a.

Definition: enter the record type and field to use as the field selector. Use the format: record type/tag/marctag/subfield/

Modify data with regular expression: Enter a regular expression in the Regular Expression text box. Use the format: <delimiter><match><delimiter><replace><delimiter>. For example, the following expression removes the hyphen from the ISSN field: /-// You can enter multiple regular expressions in one text box. Place an underscore ( _ ) between regular expressions to apply multiple regular expressions to the same data.

Test regular expression with value: enter a regular expression and click apply to test if it is valid.

Test regular expression with record number: input a specific record number, e.g. 11009263, and click apply to verify that a regular expression returns a value.

The bib record number is supplied with no preceding "b" and is followed by the check digit.

If you are going to use this field selector for a resource where it is being matched against coverage date, complete the following:

Normalize? To normalize the data from the record field before comparing it to the coverage database field, choose "Yes" for Normalize

Move coverage fields from Available to Selected.
The data from the record will be matched against data from the chosen coverage field that has been normalized according to system index rules.

Once completed save the new selector.
