Data type (property of tag definition)

For automation interface information about the Data Type property (Tag Definition Type through the automation interface), see Tag definition (automation interface).

• Boolean — Specifies that the Tag Definition stores a Boolean value. When selected, you can set the Default Value property to TRUE or FALSE.

• Enumeration — Specifies that the Tag Definition stores an Enumeration. When selected, you can specify enumeration Values and a Default Value.

• Reference — Provides a mechanism for linking a model item to a model item of a specified type, or a model item that is stereotyped by a specified Stereotype. When selected, you can specify valid Model Item Types and Stereotypes.

• Rich Text — Specifies that the Tag Definition stores rich text. When selected, you can specify a Default Value for the rich text.

• Text — Specifies that the Tag Definition stores text. When selected, you can specify a Default Value for the text.

Before you can use the Tag Definition to extend the properties of a model item, you must Publish the Tag Definition. After publishing a Tag Definition, you cannot change the Data Type value. For more information about publishing Tag Definitions, see Overview of extensibility through profiles, stereotypes, tag definitions and scripts.

You typically require database write access permissions to publish a Tag Definition. If a Tag Definition is not linked to any Stereotypes that have model item types defined, you can publish that Tag Definition without database write access permissions; however, having published the Tag Definition, you require database write access permissions to make the Tag Definition useable, that is:

• Link the Tag Definition to a Stereotype that has model item types defined.

• Define model item types for any linked Stereotypes.
