Frequently asked questions:
What is SWAMP?
SWAMP is a java-based workflow engine. The workflows are defined in an XML format, with with focus on great flexibility and the possibility for quick and frequent changes.
The workflow engine is running on a central server, with a web-GUI and a SOAP interface for human interaction and for connecting it to other systems.

What are the advantages of SWAMP compared to the many other workflow engines?
SWAMP tries to be the better solution with regard to convenience and flexibility of workflow definitions. As we have our own XML workflow definition format, we do not have to bother with the overhead of big process definition languages such as BPEL or XPDL. Another advantage is its great extendibility through being open source.

Under which license is SWAMP released?
SWAMP is released under the GPL, but depends on some libs to be present in the system at runtime. They may have other licenses:

  • Java (Sun License)
  • Graphviz (IBM Public License)
  • JavaMail, Activation Framework, JDBC, JNDI (Sun License)
  • Tomcat, Jakarta libs, Log4J (Apache Software License)
  • SoapSWAMP is based on the axis framework:
    • wsdl4j (IBM Public License)
    • saaj, jaxrpc (Sun License)
Please look on the license page for further details.

Does SWAMP include a graphical process designer?
No, the workflow definition files have to be created manually at the moment. But it is not that hard to create such a definition, please read the manual on how to create one.
There has been a Google Summer of Code project that started to create a GUI process designer based on the eclipse framework. Wiki page and Subverion repository are available.

Does SWAMP support the academic workflow patterns?
Workflow patterns as described at www.workflowpatterns.com characterize possible solutions on how to implement given requirements with a workflow engine.
There is a chapter in this document that tries to determine which of the formal workflow patterns can be modelized with SWAMP. It comes to the conclusion that most of the patterns can be used, and the engine can be extended to support those slight patterns that can not yet easily be modelled.

Has SWAMP proven to be reliable in a demanding environment?
SWAMP is the workflow management tool inside SUSE R&D / Novell. They are tracking the complete cd-creation, maintenance (tracking of patches), tracking of open job positions and tracking of Level3 support incidents within one SWAMP instance. This means ~15000 workflows and ~600 users at the moment.
