Karl F. Best OASIS - Director, Technical Operations 978.667.5115 x206

Name of TC: eXtensible Access Control Markup Language - XACML

Statement of purpose: The purpose of the XACML TC is to define a core schema and corresponding namespace for the expression of authorization policies in XML against objects that are themselves identified in XML. The schema will be capable of representing the functionality of most policy representation mechanisms available at the time of adoption. It is also intended that the schema be extensible in order to address that functionality not included, custom application requirements, or features not yet envisioned. Issues to be addressed include, but are not limited to: fine grained control, the nature of the requestor, the protocol over which the request is made, content introspection, the types of activities authorized.

List of deliverables (timing is given as days from first meeting):

  • statement of scope (45 days),
  • glossary (v1.0 45 days),
  • bibliography (v1.0 45 days),
  • use cases (v1.0 90 days),
  • detailed requirements (v1.0 120 days)
  • proposed standard (v1.0 180 days)
  • model examples for "native" and non-native XML targets of control (v1.0 180 days)
  • reference implementations (v1.0 270 days)

Related Work: To ensure work is not duplicated and standards adoption is as simple as possible, XACML shall adopt as baseline documents the work products of the Security Services TC including but not limited to a Domain Model and Glossary. Furthermore, Use Cases and Requirements documents will share content that is common through normative references. The XACML TC shall keep its work consistent with the work of the Security Services TC by requesting enhancements to, modifications of, and cross-references from Security Services TC documents through a formal liaison with the Security Services TC. This liaison will include the regular sharing of deliverables and status reports during teleconferences or at face-to-face meetings.

Language in which the TC will conduct business: English

Date, time and place of first meeting: Via teleconference at 8AM PST May 21st.

Proposed meeting schedule for first year: Teleconference calls will be held by the full TC on the second Monday of each month at 8AM PST, except when a face-to-face meeting is scheduled during the same week. A tentative date for a face-to-face meeting is XML World Sep 30th-Oct 3rd, San Jose, CA.

Names and e-mail addresses of members: Ken Yagen [], Gilbert Pilz [], Michiharu Kudoh [], Krishna Sankar [], Ernesto Damiani [], Bill Parducci [], Frank Chum [], Joe Pato [], Fred Moses [], Meg Kistin Anzalone [], Simon Blackwell []

Name of chair: Simon Blackwell []

Names of meeting sponsors: Simon Blackwell will sponsor the first teleconference and co-ordinate the first face-to-face.
