Assigning semantic types to entity and link types

Procedure

  1. In the Semantic Types dialog, load any custom semantic types specific to your organization. See Loading the semantic type library.

  2. In the Database area, click the appropriate tab to display the Entity Types or Link Types page. Depending on the settings in the lower left of the dialog, the page displays all the entity or link types defined for the current database.

  3. Select the item to which you want to assign a semantic type. The Search Available Semantic Types box displays its name. The Ordered Results area suggests some semantic types that may be suitable for assigning to the item, based on a comparison of its name with the name of the semantic type and any synonyms set up for it. For further details, see Searching for semantic types.

  4. You can review the suggested semantic types by clicking on a result to display additional information below. In particular, the description may provide some guidance on when to use the selected semantic type. The icon shown in the tree view indicates whether the semantic type is a standard type or a custom type specific to your organization.

  5. If none of the semantic types in the Ordered Results area are suitable, you can search the Semantic Type Library. SeeSearching for semantic types.

  6. When you have located the correct semantic type, you can do one of the following:

    • Select it and click Assign. (The button is unavailable if you have already assigned a semantic type to this item.)

    • Drag the semantic type from the Semantic Types area on to the appropriate item in the Database area. When dragging and dropping is not allowed, the cursor changes.

    The name of the assigned semantic type is displayed in the Database area.

    Note: If you see the message, Cannot assign abstract library types, you need to select a different semantic type. You cannot assign any of the top-level semantic types, such as Entity, Link, Abstract Text, or Abstract Number.

  7. Click OK.
