How applicable is the MPEG REL to multiple markets and product types?
The MPEG REL is not specific to any market or product type. The language has been developed by a group of experts with experience from many disciplines including content, technology and services. Although the MPEG REL was development for the multi-media industries, the language allows for any group to develop industry specific solutions that leverage the core of the language, for example the standards bodies Open e-Book Forum and TV-Anytime are developing extensions to the MPEG REL.
