The MORENA model for hypermedia authoring and browsing

This paper describes MORENA (Multimedia ORganization Employing a Network Approach), a Petri-net based platform for the description and execution of hypermedia applications. All the parts that compose the application, such as sound, video, text and buttons are described in this model and the browsing semantics are also specified. The MORENA model provides support for dynamic data, such as video or audio. It also provides structured authoring, fine-grained synchronization of media, flexibility and adaptability through message passing, user interaction, easy prototyping and simulation, and the ability to reuse logical specifications. MORENA's parent is Trellis, but it was influenced by many other systems, merging their features in a coherent and consistent framework. Applications written based on the MORENA model are compact and platform independent.
