The first meeting will be held via teleconference on 21 May 2001 at 11:00AM
Eastern Time.
The TC was created on April 16th, 2001. The following wording
was adopted for TC creation:
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.
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.
The official language of the TC is English.
The official Security
Services TC liaisons are as follows:
We know of several additional
efforts involving XML and electronic security. For those we deem particularly
relevant to our work we have assigned the following
liaisons to help ensure interoperability and avoid duplication of work:
Any individual
OASIS member or employee of an
OASIS member organization may join the TC. Voting and membership rules
are documented in the OASIS
policy governing technical committees.
Contact the TC chair or secretary if you are interested in joining the
TC and are eligible to
join. A public list of current members is
available. The following TC members have special duties.
- TC chair: Simon Blackwell, Psoom, Inc.
- Membership and Recording Secretary: open
- Coordinating Editor: open
- Website Maintainer: open
- Auxiliary Resources and Links Editor: fpaynter@sandhilltech.com
- Issues list maintainer: open
Also see the liaisons above.
Each
OASIS technical committee has a discussion list and a comment list. The Security
Services TC has the following lists:
xacml:
Subscription and posting to the TC members' mailing list is open to OASIS members only,
but the
archives are viewable by the general public. Subscribing to the list does
not constitute gaining committee membership; OASIS members must
contact the TC chair and secretary to request membership. xacml-comment: Posts to this list can be made by
the general public. Posts are automatically forwarded to xacml so that TC members will see all comments. In addition, the TC's subcommittees have the following discussion
lists, which operate under the same access rules as xacml
(though it is generally assumed that subscribers are already TC members).
the lists without a subscription link are now inactive; those subcommitttees
use the main list for discussion.
- There are currently no additional lists.
The working
documents of the TC can be found in the
document repository. The following lists may be slightly out of date;
for the latest information, always go to the repository itself.
Committee drafts:
Submissions and position papers:
Auxiliary resources and links: The following U.S.
Patents may be relevant to XACML work:
- 5,715,403 System for controlling the distribution and use of digital
works having attached usage rights where the usage rights are defined by a
usage rights grammar
- 5,629,980 System for controlling the distribution and use of digital
works
- 5, 638, 443 System for Controlling the Distribution and Use of Composite
Digital Works
The following works have substantial overlap with XACML:
The following external resources have been identified
as useful for the TC's work: TC members should note the following procedure for publishing documents
to the repository:
If your submission is covered by the document guidelines, try to ensure
that it follows the
guidelines (especially regarding file format and file name). Send mail to the xacml-editors list, attaching the submission and indicating the
list(s) to which the eventual URL(s) should be published.
If the submission needs further work with respect to the guidelines,
and the folks on the xacml-editors list can't perform this work
themselves, they'll return it to you with their requests. If the submission is (or can be made) ready to go, the editors will
put it in the repository and publish the URL.
The plan is to produce a "substantially complete" draft specification
by 21 Dec 2001, with a final version ready to undergo the OASIS member approval
process by 22 March 2002. The final version will be accompanied by reference
implementations. Below are interim deliverable dates:
- statement of scope 29 June 2001
- glossary 29 June 2001
- bibliography 29 June 2001
- use cases 24 Aug 2001
- detailed requirements 21 Sep 2001
- draft standard 21 Dec 2001
- model examples for "native" and non-native XML targets of
control 21 Dec 2001
- reference implementations 22 March 2002
Subject to approval during the first teleconference on May 21st, 2001,
teleconferences 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 face-to-face schedule will be established during the first
teleconference on May 21st, 2001. A tentative date for a face-to-face meeting,
not the first, is XML World Sep 30th-Oct 3rd, San Jose, CA.
Attendance on these teleconferences and meetings is used to assess good standing. The TC has one-hour teleconferences every
four weeks from 11:00 AM to 12:00 noon Eastern time. A face-to-face schedule will be established
during the first teleconference on May 21st, 2001. Following is the
TC/Focus meeting schedule. Agendas are tentative. Final
agendas for TC teleconferences are sent out one to two business days
ahead of time to the xacml-services list. Subsequent update of the links
below may be delayed until official meeting minutes are posted:
