open source workflow & CMS & issue tracking projects

 这篇文章汇集了最近对一系列开源工作流（引擎）、内容管理系统CMS、问题跟踪系统进行调查得到的备忘材料和一点点试用的印象。这些系统侧重方向各有不同，统称为工作流系统，因为都面向协同工作。

Open source Java Workflow Projects

WfMOpen

这个project有一个和scarab集成的应用实例，但没发现它本身以及所述实例的demo，不知道什么效果。

WfMOpen is a J2EE based implementation of a workflow facility (workflow engine) as proposed by the Workflow Management Coalition (WfMC) and the Object Management Group (OMG).

The workflow component is based on a set of JAVA interfaces that define an API for a workflow management facility. The basic "omgcore" interfaces follow OMG's Workflow Management Facility Specification, V1.2 very closely, while making some modifications to adapt the CORBA service to the established design practices for a Java API.

Workflows are specified using WfMC's XML Process Definition Language (XPDL) with some extensions.

Although WfMCore has its roots in the above mentioned workflow standards, the actual implementation transcends the traditional domain of workflow engines. By design, WfMCore provides excellent scalability and supports commodity integration technologies, including – but not limited to – SOAP. The workflow component may therefore be used as the core for any process based application implementation and is well suited to provide solutions for BPM (Business Process Management) related jobs.

Editing Process Descriptions

Any XPDL 1.0 compliant process editor may be used to create process descriptions. As XPDL is XML, actually any XML editor (and thus any text editor) is sufficient.

It has, however, turned out that a graphical representation of the process is quite helpful. We provide a graphical process editor called "JPEd". See the file download page for more information.

 

OpenWFE

OpenWFE is an open source workflow engine. It is implemented in Java, and is available under the BSD license.

OpenWFE not only features a workflow engine, but also a full fledged Business Process Management Suite. OpenWFE contains these features and many more:

• a worklist component for storing workitems (tasks) for participants,
• an APRE component, allowing you to implement automated agents into your work flows,
• Droflo, our web-based flow designer,
• and a well-documented REST interface and several libraries to access it, with more on the way.

OpenWFE can run completely standalone without any Application Server, requiring only a Java SDK (1.4.x) or better.

OpenWFE also includes several external access libraries to facilitate access to the REST interface through a variety of languages, including:
