Paper Abstract

This paper provides an overview of the three language components of DAMSEL, a framework being implemented at the University of Minnesota. It is comprised of an embedable dynamic multimedia specification language, and supporting execution environments. The goal of DAMSEL is to explore language constructs and execution environments for next-generation interactive multimedia applications. DAMSEL supports dynamic, event-driven specifications for the retrieval, presentation, modification, analysis, and storage of multimedia data. Dynamic specifications enable system, application, and user-media interactions to affect the run-time behavior. The temporal language component of DAMSEL contains two primitives for event-driven temporal specification -- supporting causation and inhibition. Specifications require (extensible) behavioral parameters to be chosen, enabling very powerful temporal relations to be defined. The dataflow language component uses a dataflow paradigm, whereby data streams flow from source to sink. Sources are live devices, or storage facilities, while sinks may include simple windows, and connections to complex layouts. Modification and analysis of a data stream takes place enroute. The presentation component supports the specification of data stream connections to user interfaces. DAMSEL components support conditional and constraint logics, enabling more complex specifications than currently possible. DAMSEL also supports an open systems view, enabling current software to be used within its architecture.
