>>Cc: members of XACML mailing list (FYI)
>>
>>[This is a deliberate cross-posting on multiple lists, for the purpose
>>of cross-fertilisation.  Apologies if you receive multiple copies.]
>>
>>As previously promised to the members of the MPEG-21 and W3C-DRM
>>mailing lists, this is an update on the activities of the OASIS/XACML
>>(eXtensible Access Control Markup Language) Technical Committee
>>following its first meeting (teleconf) on Monday 21 May 2001.
>>
>>The group charter (available at http://www.xacml.org/) includes
>>the definition of "a core schema and corresponding namespace for the
>>expression of authorization policies in XML against objects that are
>>themselves identified in XML."  (Note that the latter clause does not
>>restrict policies to XML objects, just those objects to which a
>>reference can be written in XML syntax.)  The charter further states
>>that "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."
>>
>>There is a clear synergy between the aims of XACML and other work
>>taking place in MPEG and other standards groups.  To date the TC has
>>identified a small number of potential contributing standards but the
>>Web site makes no mention of MPEG-21, IETF, Open eBook Forum, or
>>W3C(DRM) activities.  At the kickoff meeting, the TC agreed to create
>>a sub-committee with responsibility for liaison with other standards
>>efforts.  The sub-committee will help to scope the XACML work and
>>determine whether it should contribute into any other standards
>>activities, and if it could benefit from adopting the work of the
>>other activities where appropriate.  This is very positive.
>>
>>There is presently representation the XACML TC from the IETF.  Thomas
>>Hardjono <mailto:thardjono@yahoo.com> of Nortel Networks is Chair of
>>Internet Digital Rights Management Research Group of the IETF (see
>>http://www.idrm.org/).  Also, I (david.parrott@reuters.com) and a number
>>of others are bridging several standards groups in the DRM space.  It is
>>clearly useful to coordinate activities as far as possible.
>>
>>The XACML TC has an aggressive schedule (from the XACML home-page):
>>
>>'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 01 Dec 2001
>>  model examples for "native" and non-native XML targets of control 21 
>> Dec 2001
>>  reference implementations 22 March 2002'
>>
>>Of particular interest is the result of the initial scoping exercise
>>to be undertaken via the XACML mailing list and due for completion at
>>the end of next month.  I envisage that the Standards Interoperability
>>and Liaison sub-committee will have significant input during the
>>scoping phase.
>>
>>The Chair of the XACML TC is Simon Blackwell
>><mailto:sblackwell@psoom.com> who should be contacted regarding
>>participation.  NB: OASIS restricts participation in TCs to the OASIS
>>membership.  The archives of the XACML mailing list are publically
>>available at: http://lists.oasis-open.org/archives/xacml/
>>
>>
>>Background on OASIS (from http://www.oasis-open.org/):
>>
>>OASIS, the Organization for the Advancement of Structured Information
>>Standards, is a non-profit, international consortium that creates
>>interoperable industry specifications based on public standards such
>>as XML and SGML. OASIS members include organizations and individuals
>>who provide, use and specialize in implementing the technologies that
>>make these standards work in practice.
