Data type and attribute items identify data types (defined as subtypes) and attributes that are in addition to the Windchill modeled classes.

The data types available in a context are determined by the data types defined in the organization context, as well as those defined in the site context.

For example, if your organization context has defined Plan and Report document subtypes, then these subtypes are available in any project, program, product, or library context created from your organization context.

All data types that are modeled in your Windchill solution are available for administrator use from the site context.

If Windchill ProjectLink is installed, then the following document subtypes are also available from the site context:

During the installation process, an organization participant (the organization object) is created and associated with the site context. Any types owned by this organization participant are available to all organizations.

Each organization participant has an internet domain that is used to identify the organization contexts for subtypes and attributes. When subtypes and attributes are created, Windchill provides a suggested prefix for the name of the new type or attribute. The suggested prefix is based on the context from which the Type and Attribute Management utility is launched. The suggested prefix is the reverse of the internet domain for the owning organization participant of the organization context. For example, an organization with the internet domain, acme.com would suggest the prefix, com.acme.
