Executable Workkows: a Paradigm for Collaborative Design on the Internet

{ This paper introduces a directed hypergraph model that supports (1) workkow composition and reconnguration while accessing and executing programs, data, and computing resources across the Internet, (2) synchronous and asyn-chronous peer-to-peer interaction between members of any team during workkow composition and execution, (3) synchronous and asynchronous peer-to-workkow interaction between any team member and any object in the workkow. Given a library of program and data nodes, editing the workkow and its execution is as intuitive as the hierarchical schematic design capture and simulation. Examples of multi-site multiuser applications demonstrate that the proposed workkow implementation provides a user-friendly paradigm for distributed and collaborative team design.
