Define a Conditional Validation Rule
You can define a conditional rule to identify the tags and subfields that must be present or prohibited if a particular tag, indicator, or subfield is present. To define a conditional validation rule:
- In the Administration Explorer tree view, expand the System folder.
- Select Profiles and select the Cataloging tab.
- Select MARC validation: Bibliographic or MARC validation: Authority.
The MARC Validation Editor appears for the selected MARC format.
- Select the tag in the MARC Fields list for which you want to create a conditional validation rule.
Tip:
You cannot set conditional rules for the Leader, control fields, fixed fields (fields less than 010) or indicators.
- In the Rules list, click to open a conditional rule row.
The selected tag number is displayed in the first column of the first available row in the Rules list.
Tip:
To delete the rule, select it under Tag Level Rules, and click the delete button.
- Type the indicator or subfield in the appropriate column, select the box in the Condition column in the same row, and specify the condition:
- Select must have if the tag or subfield is required. For example, a 490 tag must have an 830 tag.
- Select must not have if the tag or subfield is prohibited when the tag is used. For example, a 100 tag must not have a 110, 111, or 130 tag.
- Select File > Save.
