Subject: XACML TC Charter revision - latest version
Here is the charter with minor refinements. Notes: 1. Scope has been expanded - to include an authorization model. 2. Non-goals of XACML are still missing (if any of you want to take a stab at it, please do) We can talk about this tomorrow. ---------------------------------------------------------------------------- ----------------- Product of TC XACML TC will define a core XML schema for representing entitlement policies, also called XACML Policy Target The target of a policy (hereafter referred to as "target") can be any object that can be referenced in XML. Protocols and bindings XACML TC will define new protocols or identify bindings to existing protocols (e.g., XPath, LDAP) intended as means of accessing and communicating the policies Scope XACML is expected to address fine grained control of authorized activities, the effect of characteristics of the access requestor, the authorization protocol over which the request is made, authorization based on classes of activities, and content introspection (i.e. authorization based on both the requestor and potentially attribute values within the target where the values of the attributes may not be known to the policy writer). XACML is also expected to suggest a policy authorization model to guide implementers of the authorization mechanism. Extensibility XACML core schema is extensible for as yet unknown features Interoperability XACML TC will define interoperability of XACML core schema with other standards Simon Blackwell Suresh Damodaran Fred Moses -----------------------------------------------------www.stercomm.com------- ------------------------------------------------------ Suresh Damodaran, Ph.D. Sterling Commerce, a SBC Company Senior Software Architect 750 W.
