Manage custom semantic types - Precisely Data Integrity Suite

You can edit existing custom semantic types to update their properties, matching rules, and configurations. You can also delete custom semantic types when they are no longer required.

1. Go to Configuration > Catalog > Semantic Types.
   The Semantic Types list displays all available semantic types in your workspace.
2. Locate the semantic type you want to edit or delete in the list.
3. You can use the search field or filter options to find specific semantic types by name, base type, or source.
4. Click the ellipsis next to the semantic type name.
5. A context menu appears with available actions for that semantic type.
6. Select Edit to modify the semantic type properties. The Edit Semantic Type dialog opens, displaying all configurable properties.
   1. Modify any of the following properties as needed:
      • Name: The display name of the semantic type
      • Qualifier: The unique identifier for the semantic type
      • Description: Optional details about the semantic type's purpose
      • Threshold: The confidence level required for matching (0-100%)
      • Priority: The priority ranking when multiple semantic types match
      • Base data type: The underlying data type (such as String, Long, Double)
      • Asset Match Criteria: The matching rules including regex patterns and match type
   2. To test your regex pattern, enter a sample data value in the Test a data value field and click Test.
      The system validates your pattern against the sample data and displays the result.
   3. Click Save Changes to apply your modifications.
   4. Click Cancel to discard your changes and close the dialog.
   Note: Built-in semantic types have limited editing capabilities. You can only modify the name, description, and display properties. The matching rules and base data type for built-in types cannot be changed.
7. To delete a semantic type, click the ellipsis next to the semantic type name and select Delete.
   1. A confirmation dialog appears with important information about the deletion.
   2. Review the warning message carefully:
      • If the semantic type is currently assigned to assets, the system displays the number of assets that will be unassigned.
      • All information about the semantic type will be permanently deleted.
   3. Click Delete to confirm the deletion, or click Cancel to stop.
   Warning: Only custom semantic types can be deleted. Built-in semantic types are protected and cannot be removed from your workspace. If you attempt to delete a semantic type that is assigned to assets, those assets will be unassigned from the semantic type. This action cannot be undone.
