Anne,
I'd
like to clarify a couple of things regarding XrML in
your minutes.
Regarding
access to the XrML specification from www.xrml.org, NO agreement with ContentGuard
is required. You all are free and welcome to obtain the XrML
specification and related materials. All you have to do is to register with the
site, so that the specification package can be emailed to your attention. By
the way, ContentGuard is submitting XrML to the Rights Language TC within OASIS. Once the TC
becomes operational, you will be able to get the latest XrML
specification directly from the TC.
In
terms of the scope of XrML, it is intended to be
agnostic to resource that rights are associated with. Also XrML
covers the entire spectrum of the lifecycle of the resource, including
issuance, delegation, transfer, and other aspects of management of rights, and
it supports various business models that are common and useful in practice.
Regards,

Policy Model teleconference
Minutes of Policy Model Subcommittee Teleconference Meeting
25 March 2002
Scribe: Anne Anderson
Present: Carlisle, Simon, Anne, Ernesto, Tim, Pierangela, Polar,
Michiharu, Don
ACTION ITEM: Polar agreed to attempt to write new resolutions
for issues PM-3-03, PM-3-03A, and PM-2-05.
ACTION: Carlisle and Tim look at the last few items in these
minutes and report whether they participated in the vote.
1. Discussion of OASIS Rights Language Technical Committee
Attendees discussed how the XACML TC should respond to and
coordinate with the new OASIS "Rights Language" TC. Several
XACML participants see potential overlap. Carlisle said he
would talk to Carl Best and others about potential overlap,
and whether we actually need to have two groups. Carlisle
plans to participate in the Rights Language TC in order to
track its efforts and to ensure XACML coordination occurs.
Tim pointed out that one currently has to enter into an
agreement with ContentGuard in order to see their XrML
specification, so it is difficult to assess any potential
overlap. Carlisle will also bring this issue up with Carl
Best.
Simon has viewed the XrML specification and, while not
prepared to give a full review, made the following points: it
is much more specialized than the XACML language, such as
having specialized targets for media. It does support
delegation, but does not support composition of policies from
different sources.
