wftk

Opensource workflow toolkit, is the name of a generalized workflow system, implemented as a series of Java libraries. wftk was begun in 1998 by Michael Roberts. wftk uses its own high level language to describe workflow, and stores workflow related documents in a series of XML datasheets. wftk workflow engine contain two models of a workflow: a taskbased model, essentially a DAG, and a statebased model, essentially a FSM. wftk libraries can also be run as web services.
