PTC Document Management Domain
The Document Management domain provides access to the document management capabilities of Windchill. It enables you to create documents. You can upload and download content from documents.
You can also create classified documents. To create a classified document object using Windchill REST Services, follow the same initial steps as in the Windchill user interface. Import the classification structure, create a classification binding attribute on the document object, and use the endpoints with relevant payload to create a classified document. For more information on classifying objects, see the Windchill Help Center.
You can also update the classification attributes for existing classified documents.
When creating or updating a classified document, the request returns the relevant error messages if you specify an incorrect classification node name, attribute name, or attribute value.
