WEBWORK - METEOR2S WEB-BASED WORKFLOW MANAGEMENT-SYSTEM

METEOR2 workflow management systems consist of both (1) design/build-t ime and (2) run-time/enactment components for implementing workflow ap plications. An enactment system provides the command, communication an d control for the individual tasks in the workflow. Tasks are the run- time instances of intra- or inter-enterprise applications. We are deve loping three implementations of the METEOR2 model: WebWork, OrbWork an d NeoWork. This paper discusses WebWork, an implementation relying sol ely on Web technology as the infrastructure for the enactment system. WebWork supports a distributed implementation with participation of mu ltiple Web servers. It also supports automatic code generation of work flow applications from design specifications produced by a comprehensi ve graphical designer. WebWork has been developed as a complement of i ts more heavyweight counterparts (OrbWork and NeoWork), with the goal of providing ease of workflow application development, installation, u se and maintenance. At the time of this writing, WebWork has been inst alled by several of the LSDIS Lab's industrial partners for testing, e valuation and building workflow applications.
