The Tracked Resource Set (TRS) specification allows a server to expose a set of resources in a way that allows clients to discover the exact set of resources in the set, to track all additions to and removals from the set, and to track state changes to all resources in the set.
Tracked Resource Set as well as the Global Configuration Management Application require a functional user to access (in read-only) products and retrieve Windchill artifact content.
