Working PDP

I have successfully built a PDP that is capable of using the RAdAC policies I have been working on. The only thing I don't like is that it is difficult to change the risk associated with a particular factor. For example, someone with Top Secret clearance is more trustworthy than someone with no clearance, but each level has a numeric value of risk associated with it. To change the numeric value, you must change the source. I'm thinking of storing the values of risk in a file that would be easy to edit or, even better, making a GUI. In any event, now that it is working I can begin working on the testing portion of the project. I will begin that this week.
