6. Digital Rights Expression Languages
6.1 XrML
XrML provides a universal method for securely
specifying and managing rights and conditions
associated with all kinds of resources including
digital content as well as services.
XrML can be used in content-centric as well
as service based business models. Rights and
conditions can be securely assigned at varying
levels of granularity to individuals as well
as groups of individuals and the parties can
be authenticated. In addition, the grants/licenses
can be interpreted and enforced by the consumption
application. XrML is designed to be used in
either single tier or multi-tier channels of
distribution with the downstream rights and
conditions assigned at any level. In addition,
the trust environment can also be specified
in the language in order to maintain the integrity
of the rights and conditions.
XrML is licensed from ContentGuard.
6.2 ODRL
The Open Digital Rights Language (ODRL) Initiative
is an international effort of Supporters aimed
at developing an open standard for the Digital
Rights Management sector and promoting the language
at numerous standards bodies.
The ODRL specification supports an extensible
language and vocabulary (data dictionary) for
the expression of terms and conditions over
any content including permissions, constraints,
obligations, conditions, and offers and agreements
with rights holders.
The ODRL specification is freely available and
has no licensing requirements.

...<indecs>rdd is a consortium-based initiative
to develop a rights data dictionary. Its purpose
is to support the implementation of a rights
language for secure exchange of intellectual
property on networks. The initiative, based
on the original <indecs> analysis (1998-2000:
http://www.indecs.org/),...
...It is not a Rights Expression Language (REL).
A data dictionary is not an expression language
(such as XrML, now adopted as baseline technology
for the MPEG-21 REL standard). An REL deals
with the way in which terms are expressed in
computer language; the dictionary defines the
terms. An REL will use terms defined in an RDD...
