Synthesis of Hypermedia using OWL and Jess

An hypermedia is a spatio-temporal hypertext, namely a collection of media connected by synchronization and linking relations. HyperJessSyn is a tool which uses logic programming and Semantic Web technologies for synthesizing hypermedia according to descriptions of discourse structure and of presentation layout. A rule-based system in Jess applies inference rules to interpret from an OWL graph semantic and navigation relations among media instances, and production rules to turn media contents descriptions in XML/MPEG-7 format in an XMT-A/MPEG-4 hypermedia script via XSL transformations. The system has been used to produce an hyper-guide for virtual visiting a museum.
