Werkflow is a flexible, extensible process- and state-based workflow engine. It aims to satisfy a myriad of possible workflow scenarios, from enterprise-scale business processes to small-scale user-interaction processes. Using a pluggable and layered architecture, workflows with varying semantics can easily be accomodated. Processes can revolve around documents, objects or any other entity. The core werkflow engine can be accessed through a Java API, EJB, JMS, SOAP and other conduits.
