- Thread-topic: [xml-dev] XACML Research.
I was working with XACML implementation in a .Net environment, and it was interesting for us. We have implemented in an internal project for resource management (books, CDs, DVDs, projector, etc) and it was very interesting. Some of the limitations of XACML (support for hierarchical resources requires too much configuration) were an issue, but we were able to solve them. Regarding the speed of development, every applcation requires some kind AccessControl management and we were able to save that development time. Some other interesting points for XACML is that a single language must be learned to define AccessControl policies for any project.
My favourite feature of XACML is the how powerfull the language is, and of course very extensible (funtions, data types, combination algorithms, etc). It allows to express a wide range of rules with a very simple language.
About the future of XACML, I have my point of view, I think Semantic Web technologies are growing faster, specially for the rule definition ontologies like SWRL, RuleML, DAML, etc. Those new rule based languages will make the "constraint definition markup languages" (like XACML or WS-Policy) to be based in the new rule definition technologies. CWM  is a sample of Access Control defined with semantic web technologies.
There are some advances in such direction , and .
Hope this helps,

Subject: [xml-dev] XACML Research.
Hi,i am currently an MSc student and doing my dissertation research on The implement XACML on Grid System as a whole solution for users Access control.
I wanted some information on where to find relevent information or link for the following:
1.The impact of XACML
-How it effects the Access-Control Technology?
-an example of such implementation
2. Next enterprise applications persistence J2EE based XML Access Control System or any other live implementation example and future perspectives.
and finally FUTURE OF XACML
I know theses are very specific questions bu any response to any of the above is much appreciated.
sorry if any inconvenience caused.
hope to hear soon
