I’ve been recently working on an interesting little project: converting XACML 1.1 policy (sets) to XACML 3.0 policies in order to help migrate a customer from a legacy environment to Axiomatics.
In order to proceed with the conversion, I decided to use stock tools available off-the-shelf and custom code as little as possible. Since I write in Java, I chose to go for JAX-B especially since the support for JAXB has become better and better over the years. XJC itself is part of the JDK and it makes generating Java classes from XML schemas a breeze.
I’ll talk some more about that in a separate post. In the meantime though, I wanted to share with you an old picture, the class diagram for XACML 1.1. I extracted it from the core specification documentation which can be found here.
In this class diagram, the structural elements of XACML are clearly shown:
I’ll keep you updated on the conversion progress.
