Workflow Engines

werkflow

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.

 

pegasus

Pegasus (Planning for Execution in Grids) is a workflow mapping engine that automatically maps high-level workflow descriptions onto distributed resources. It takes a description of computational tasks to be performed and adds the necessary data transfers and data registration tasks (optionally). Pegasus uses the Condor DAGMan execution engine to execute on Condor pools, and clusters managed by PBS and LSF. Pegasus can optimize the workflow performance and reliability.

 

bpmscript

BpmScript is a continuation based scripting platform for Business Process Management. Features include:

 * Clustered processes
 * Worklist Support
 * ServiceMix JBI integration
 * Web Management Console
 * Versioned Processes
 * Child Processes
 * Remote API
 * Half Async Processes
 * Parallel Processes

 

enhydra-shark

Shark is an extendable workflow engine framework including a standard implementation completely based on WfMC specifications using XPDL (without any proprietary extensions !) as its native workflow process definition format and the WfMC "ToolAgents" API for serverside execution of system activitie

 

beexee

Bexee is a BPEL engine capable of executing deployed business processes described in BPEL by orchestrating existing Web Services.

 

apache-ode

Apache ODE (Orchestration Director Engine) executes business processes written following the WS-BPEL standard. It talks to web services, sending and receiving messages, handling data manipulation and error recovery as described by your process definition. It supports both long and short living process executions to orchestrate all the services that are part of your application.

 

syrup

An adaptive workflow engine based on simple concepts. It offers full persistence, so that work is never lost, and deals with partial failure in a distributed setup. Syrup is also used reliably as a distributed scheduler to replace cron.

 

micro-flow

The micro-workflow framework targets developers who want to separate the control and logic aspects in their programs, thus making them flow independent. A well-factored flow independent application facilitates change because the most frequent business changes translate into process changes, thus leaving the code intact.
