Open source framework to build Web based BPMN designer

Question

We have already built a BPMN designer on eclipse framework.It was easy to build with great support from eclipse based frameworks like EMF, Graphitti etc. Now we want to build a web based BPMN designer. Can you suggest which open source frameworks i can use to do this ? I would expect the framework to support me in defining the bpmn metamodel, a graphical editor ect etc

Please share your ideas.

Answer 1

Oryx / Signavio Core Components

The Signavio Core Components are the "sucessor" of Oryx. A github mirror is available there: https://github.com/IAAS/signavio-core-components/

The Signavio Core Components switched from MIT to GPL license. Furthermore, they are unmaintaned.

Forks

Wapama is a fork of Oryx. It seems that https://github.com/saifulomar/process-designer is the most recently updated fork with a tight JBPM integration.

Gemsbok is another fork of the Signavio Core Components.

process-designer seems to be actively maintained (as of 2013/06)

The dependency to ExtJS was removed in the context of the Flowable project. See https://github.com/flowable/flowable-engine/tree/master/modules/flowable-ui-modeler/flowable-ui-modeler-app/src/main/resources/static/editor-app/editor for the current source.

Eclipse Stardust / Lightdust

There is also recent by the Eclipse community. Within the Stardust project, there is a web-based BPMN Modeler, accessible via git: http://git.eclipse.org/c/stardust/org.eclipse.stardust.ui.web.git/tree/stardust-web-modeler-bpmn2. Some basic information is in the Stardust Wiki, but no step-by-step-guide for using the web-based BPMN modeler standalone.

Self-implemented

We made a comparison of all available web-based graph-libraries at https://ultimate-comparisons.github.io/ultimate-graphframework-comparison/.

Example code of the best ones is available at https://winery.github.io/javascript-graph-library-comparison/. The idea is similar to TodoMVC, but here a minimal example for graph creation is made.

(Some old comments follow)

jsPlumb-based

There is the project https://github.com/Dzhyrma/BPMN_Modeler, which is based on jsPlumb. It includes raphael, which is a SVG-based graph-drawing library.

Direct canvas drawing

https://github.com/hallodom/BPMN-Modeller directly uses the 2d canvas to draw BPMN.

Answer 2

http://bpmn.io/ is the best answer if the license terms (include logo) work for you.
