Subject: RE: XACML TC Charter Revision - Strawman
>Policy Target >The target of a policy (hereafter referred to as "subject") can be any >object that can be referenced in XML. In my experience, the term "subject" would more usually refer to the principle requesting access to a resource. I can't tell for sure if XACML policies are exclusively resource-centric (a list of principles/groups/roles that have access to a given resource) or also encompass principle-centric policies (i.e. a list of the resources a given principle has access to). Or maybe we want to be able to express both. However, I don't think "subject" is appropriate when talking about the target for resource-centric policies. (It would be OK for principle-centric ones.) Instead of "subject", why don't we just use "target"? I think that covers both the principle-centric case and the resource-centric one fairly nicely. Regards, Marlena Erdos IBM/Tivoli
