The Burton Group has released its XACML Interoperability report

The Burton Group has finally released it's report about the XACML Interoperability Demonstration held at the Catalyst Conference in June this year. If you have a subscription, you can download the full PDF.

The summary:

Burton Group hosted the first-ever eXtensible Access Control Markup Language (XACML) interoperability demonstration at its 2007 Catalyst Conference North America. XACML 2.0 was formally ratified in March 2005, but no interoperability work had been attempted until early 2007. At that time, the XACML Technical Committee (TC) of the Organization for the Advancement of Structured Information Standards (OASIS) accepted the challenge of coordinating this inaugural event. In cooperation with eight vendor participants, OASIS demonstrated fundamental interoperability in two usage scenarios: policy exchange and authorization decision processing.

The successful outcome of this demonstration event proves that basic interoperability between XACML-based products can be achieved, which is timely, because interest in and adoption of XACML continues to increase across the industry. However, one demonstration does not replace a program that certifies interoperability as more vendor products adopt XACML. In addition, work is underway on XACML 3.0, which will introduce new functionality to test.

I've previously written about IBM's involvement in the event.
