Authoring multimedia documents through grammatical specifications
نویسندگان
چکیده
The diversity of multimedia devices is an important feature on the Internet, which demands an executable mechanism to intelligently adjust the appearance of a document according to different viewing contexts. In order to satisfy this requirement, a graph-grammar-based approach for multimedia authoring is presented by extending a context-sensitive graph grammar formalism, Reserved Graph Grammar (RGG), with the capability of spatial specifications. Based on a parser for the RGG, a graph grammar functions as a mapping from the structure of a document to a desirable layout, and graph transformations are automatically performed when contexts are changed.

Multiviews Interfaces for Multimedia Authoring Environments
This paper discusses the interface needs for the emergence of new authoring tools for the creation of multimedia documents. We think that it is possible to break down the specify-and-run process of most existing tools to have more direct editing functions close to a ”wysiwyg” approach. After identifying the requirements of direct editing for multimedia documents, we describe an authoring enviro...

The research project MAVA (Multimedia Document Versatile Architecture) focuses on simplification of specification and dissemination of multimedia documents. The problems discussed and solved by the MAVA approach are observed by using existing authoring systems. Application specific multimedia systems provide fixed concepts for only one application area. Generic systems allow the specification o...
