ContentGuard intends to submit XrML to standards bodies that are developing
specifications that enable the exchange and trading of content as well as the
creation of repositories for storage and management of digital content. Some of
the areas of technological standards work into which we expect to submit XrML
for consideration would be in DRM, Metadata, Content Management, Content Delivery
and Distribution, and Access Control/Security Services.
We have also
strived very hard to maintain a broad scope of applicability for XrML with respect
to media type. The content "products" of the future will be collections of many
types of content in many forms. Text will be combined with graphics, streamed
video/audio, and subscription-based content available from a particular network
resource or web service. Because of this confluence of content types we expect
to submit XrML for consideration as the Rights Management Language in standards
efforts in the areas of eBooks, digital publishing, digital broadcasting, music,
video, digital cinema, digital TV, and all other content/media types.

Standards Bodies Activity |

The
Moving Picture Experts Group (MPEG)
is a working group of ISO/IEC, JTC 1 / SC 29 / WG 11
in charge of the development of international standards for
compression, decompression, processing, and coded representation
of moving pictures, audio and their combination. ContentGuard's
XrML architecture has been selected as a basis for the development
of the MPEG-21
Rights Expression Language (REL). ContentGuard
is very active in this work and a ContentGuard representative
is currently a Co-Editor of the standard in development. The
rights language is expected to reach final committee draft,
FCD, in December 2002. The final draft of the ISO standard
is expected by the summer of 2003.

The Organization
for the Advancement of Structured Information Standards
(OASIS) develops standards largely
based on XML. ContentGuard has contributed XrML to OASIS,
thus providing an open forum with broad industry participation,
for the future development and governance of XrML. ContentGuard
personnel chair the Technical Committee on
Rights at OASIS. Other founding members include
Hewlett Packard, Microsoft, Reuters, VeriSign, IBM. ContentGuard
also participates in the WSS TC.

The Open
eBook Forum (OeBF) is the leading international trade and standards
organization for the eBook industry. ContentGuard is a member of the Rights &
Rules and IP Policy working groups. The Rights and Rules Working Group (RRWG)
has selected XrML as a foundation rights expression language for developing detailed
material in its Rights Grammar specification. The working group has also established
a formal liason with MPEG-21. |

|
The TV-Anytime
Forum is an association of organizations which seeks to develop specifications
to enable audio-visual and other services based on mass-market high volume digital
storage in consumer platforms. XrML is under consideration as a standard rights
expression language by their Rights Management and Protection working group. The
Rights Management and Protection Information subgroup has developed tvax, an XrML
extension for TV-Anytime. TV-Anytime Forum issued a Call for Contributions in
April 2002 for its Phase Two activities. Three distinct areas of enhancements
has been identified for Phase Two: New Content Types, Targeting, and Redistribution.
ContentGuard personnel contribute to the Rights Management and Protection working
group. |

The Publishing Requirements
for Industry Standard Metadata (PRISM) is an extensible XML
metadata standard for syndicating, aggregating, post-processing and multi-purposing
content from magazines, news, catalogs, and mainstream journals. XrML is referenced
in their latest specification and ContentGuard is actively participating in this
working group. |
