Abstract

METEOR_2 workflow management systems consist of both (1) design/build-time and(2) run-time/enactmentcomponents for implementing workflow applications.An enactment system provides the command, communication andcontrol for the individual tasks in the workflow.Tasks are the run-time instances of intra- or inter-enterpriseapplications. We are developing three implementations of the METEOR_2 model: WebWork, OrbWork and NeoWork.This paper discusses WebWork, an implementation relying solely on Webtechnology as the infrastructure for the enactment system.WebWork supports a distributed implementation with participation ofmultiple Web servers. It also supports automatic code generation of workflow applicationsfrom design specifications produced by a comprehensive graphical designer.WebWork has been developed as a complementof its more heavyweight counterparts (OrbWork and NeoWork),with the goal of providing ease ofworkflow application development, installation, use and maintenance.At the time of this writing, WebWork has been installed byseveral of the LSDIS Lab‘s industrial partners for testing,evaluation and building workflow applications.
