Hi Somaya,

could you elaborate a bit more on your goals? Do you want to investigate 
interactions between different frameworks (using the same policy language and 
characteristics) or mapping between different policy languages?

If you refer to the latter, there was a short paper in POLICY 2007 ("Web Rule 
Languages to Carry Policies") on that direction. However, my main concern is 
about the scenario in which such approach is useful. If you try to map two 
different policy languages, there are two possibilities:
- Both languages have same expressiveness. Otherwise, part of the meaning of 
the policy is lost. I don't know of scenarios in which that would be 
acceptable, but if you have I would be very interested.
- Identify the common subset of the two languages and restrict the policies to 
that subset in order to allow for 100% mappings.
