Unique Identifiers for objects in the Repository

TDC maintains identifiers for all objects in the repository. These are unique when both the Object Id and the Model ID are specified. In addition, TDC also computes a Stable Id . A Stable Id:

  • Is unique to an object within the context of a configuration
  • Is used in the URLs presented at the top of web page results so that one may copy and paste using the Stable Id
  • Is unlike the Object Id in that the Stable Id remains fixed even as new versions of harvested metadata are include (replaced) in the configuration.

In this way, it is almost always best to use the Stable Id (as in the URLs) when trying to link to an object or location in the repository from outside the tool.
