PML: adding flexibility to multimedia presentations

摘要

In multimedia systems, designers typically link content and presentation. The paper discusses a new markup language, Procedural Markup Language (PML), which decouples content and presentation. It lets users specify the knowledge structures, underlying physical media, and relationships between them using cognitive media roles. This approach fosters modular system design and dynamic multimedia systems that can determine appropriate presentations for a given situation by allowing knowledge specification to be done separately from knowledge presentation.
