Abstract: Data flow graph representation is combined with message passing and delegation, a stackless execution model, and a real-time compiler technology, to provide an improved software development and distribution paradigm. Polymorphic objects represent nodes that can be reconfigured, replaced, and/or modified as needed. Complex functionality is achieved by passing messages among nodes. Authored content is published by replacing interactive nodes with fixed-value nodes as desired. Software representations can be translated among various isomorphic formats, including data flow graphs and scripts, without loss of information or modifiability.
