The standards around hypermedia documents wrap all technologies for Digital Television and Web delivery such as transmission, content, software layer and return channel. This paper focuses in the software layer, also know as middleware. Many standard multimedia languages have a similar syntax and semantics to describe hypermedia documents, such as Synchronized Multimedia Integration Language and Nested Context Model. However, each one of these languages can only be interpreted by its specific middleware. This scenario generates an enormous problem because a hypermedia document model designed for a specific standard can not be widely shared. Consequently, a same hypermedia document must be translated in several other standards to be widely shared, increasing the authoring efforts and waste of time. This paper introduces a model driven approach to support the widely sharing of hypermedia documents.
