Current revision
The MPEG-21 standard, from the Moving Picture Experts Group aims at defining an open framework for multimedia applications. ISO 21000.
Specifically, MPEG-21 defines a "Rights Expression Language" standard as means of sharing digital rights/permissions/restrictions for digital content from content creator to content consumer. As an XML-based standard, MPEG-21 is designed to communicate machine-readable license information and do so in an "ubiquitous, unambiguous and secure" manner.
Among the aspirations for this standard that the industry hopes will put an end to File Sharing is that it will constitute: "A normative open framework for multimedia delivery and consumption for use by all the players in the delivery and consumption chain. This open framework will provide content creators, producers, distributors and service providers with equal opportunities in the MPEG-21 enabled open market."
The right of the consumer not to have to pay multiple times for the same content in different formats is conspicuously absent.
