DRAMA Releases PDP Framework

Hi all,

The DRAMA Project (http://drama.ramp.org.au) has recently released a standalone web services based PDP implementation that makes use of Sun's XACML implementation.

The PDP implementation provides two web services. The first is the PDP itself which allows for the evaluation of XACML requests. The second is a policy administration interface (PAP – Policy Administration Point in XACML architecture) which allows adding, deleting, updating and searching of policies to the policy store.

For the policy store, the PDP makes use of the Berkeley DB XML database, which is freely available from Oracle at http://www.oracle.com/database/berkeley-db/xml/index.html. This allows for large numbers of policies to be stored while still providing excellent performance. Being an XML database, there is no required structure for the policies stored within and as such allows for policies with arbitrary complexity, which is one of the strengths of XACML.

The implementation provides pluggable interfaces for Attribute Finders, Policy Combination Algorithms and even substituting in your own custom policy store should you wish it.

The software is released under the Apache 2.0 License.
