PTC Domains
This section explains the domains provided by PTC in Windchill REST Services.
When you install Windchill REST Services, some domains defined by PTC are also installed. These domains enable you to work with Windchill types in the REST architecture. You can also create new custom domains, or extend an existing domain to enable more entities.
A domain in Windchill REST Services represents a RESTful web service, which follows the OData standard. A domain describes its Entity Data Model (EDM) by defining the entity sets, relationships, entity types, and operations.
