| 3. OSWorkflow | | By: | | | License: | Apache Software License | | URL: | http://www.opensymphony.com/osworkflow/ | | Description: | OSWorkflow is fairly different from most other workflow systems available, both commercially and in the open source world. What makes OSWorkflow different is that it is extremely flexible. This can be hard to grasp at first, however. For example, OSWorkflow does not mandate a graphical tool for developing workflows, and the recommended approach is to write the xml workflow descriptors 'by hand'. It is up to the application developer to provide this sort of integration, as well as any integration with existing code and databases. These may seem like problems to someone who is looking for a quick "plug-and-play" workflow solution, but we've found that such a solution never provides enough flexibility to properly fulfill all requirements in a full-blown application.

| 4. con:cern | | By: | | | License: | GNU Library or Lesser General Public License (LGPL) | | URL: | http://concern.sourceforge.net/ | | Description: | con:cern is a workflow engine based on an extended case handling approach. A process is described as a set of activities with pre- and postconditions. An activity is executed when its preconditions are met. It manipulates the process item, thereby creating postconditions. The process flow is determined at run-time. This approach is superior to the conventional process flow approach, if at least one of the following statements applies:
* complex process with exceptions and special cases
* execution sequence is dependent on multiple factors
* possibility of manual intervention of process flow
* content-based dependence amongst activities
* strong requirements to modularity
* strong requirements to flexibility
* loose process coupling

| 7. Open for Business Workflow Engine | | By: | | | License: | MIT License | | URL: | http://www.ofbiz.org/docs/workflow.html | | Description: | The Open for Business Workflow Engine is based on the WfMC and OMG specifications. (See the related documents for information on these specs.) The Workflow Engine is a member of the Services Framework, and is tightly integrated with the Entity Engine. It uses the entities found in entitymodel_workflow.XML for definition information and entitymode_workeffort for runtime storage. All changes to a process or activity are persisted real-time. Therefore, the engine does not run in a thread, it is simply a group of APIs and common objects which handle the flow. When a change to the workflow is made, the engine then processes that change. When finished, the engine returns. Hence, if the application does crash, or the system reboots, the workflow will continue right where it left off upon restart.

| 9. WfMOpen | | By: | | | License: | GNU General Public License (GPL) | | URL: | http://wfmopen.sourceforge.net/ | | Description: | 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.

| 10. XFlow | | By: | | | License: | Apache Software License | | URL: | http://xflow.sourceforge.net/ | | Description: | XFlow is a pure J2EE platform for building, executing and managing business processes and workflows. It is a basis for building collaborative applications as well as integrating processes across an enterprise. XFlow has a small footprint but is extremely powerful. It is designed to be easy to use from the development, deployment and management standpoints.
XFlow runs within an EJB and servlet container. JBoss 4.0 (with bundled Tomcat) is the container used in this implementation. The architecture supports distributed and parallel processes within an organization's firewall as well as across organizational boundaries.
XFlow is designed for scalability, extensibility and ease of integration with security models and legacy processes. XFlow's service-oriented architecture supports both a simple Java API as well as a web-service (SOAP/HTTP) interface.

| 13. Freefluo | | By: | | | License: | | | URL: | http://freefluo.sourceforge.net/ | | Description: | Freefluo is a workflow orchestration tool for web services initially developed by IT Innovation but now available to all from the Freefluo Sourceforge Site. It can handle WSDL based web service invocation. It supports two XML workflow languages, one based on IBM's WSFL and another named XScufl that is under development as part of the Taverna Sourceforge project.
Freefluo is very flexible, at its core is a reusable orchestration framework that is not tied to any workflow language or execution architecture. Freefluo includes extension libraries that enable execution of workflows written in a subset of WSFL. Support exists for for discovery via standard UDDI and recording of provenance.
Freefluo is one component within the myGrid toolkit. The myGrid toolkit is composed of numerous useful software components. These components are designed to demonstrate higher level functionalities over an existing Grid infrastructure that support scientists in making use of complex distributed resources. These higher level functionalities extend through service lookup and discovery, provenance and data storage.

| 18. Dalma | | By: | | | License: | GNU Library or Lesser General Public License (LGPL) | | URL: | http://https://dalma.dev.java.net/nonav/maven/index.html | | Description: | Many applications of today need to have a part of the program that waits for other entities. For example, a mailing list manager waits for an e-mail to trigger actions. A web application waits for incoming HTTP requests.
Sometimes those applications are conversational; they not only just receive messages, but also send out messages. Those programs often maintain some state and change it as the conversation progresses. Often there are multiple conversations running concurrently. Those are what we call "workflow" applications.
