Understanding the Namespace

MACE (the Middleware Architecture Committee for Education) has delegated the operations of the Uniform Resource Name (URN) namespace to UT Austin Information Technology Services.

This namespace supports the assignment of unique, global, persistent names to resources used by UT Austin in its Shibboleth, directory services and other middleware initiatives.

For more information about URNs, see:

  • Internet2/MACE Uniform Resource Name (URN) registry home page.

  • RFC 3613, which defines the urn:mace namespace and describes the procedures and policies governing its use.
