[Carbon-dev] Interactive BPEL process diagrams in BPS

[Keheliya Gallaba]

I am working on improving the visualization of WS-BPEL 2.0 process instances
running in BPS to provide more information about their current state.

As I found, an open source online BPMN editor called Oryx with the BPEL
extension has the potential to be used since it can be customized to use as
a SVG generator and easily embeddable on pages using its lightweight
javascript based MOVI API. But there are some issues when importing the BPEL
file and generating the PNG image for publishing. Apparently developers have
discontinued the support for this project as they are moving into a
commercial product called 'Sygnavio' and lot of documentation is available
in German.

If you have any suggestions for other frameworks that can be used for BPEL
diagramming, please suggest. Famous js frameworks like Raphael,
Processing.js and infovis (and cytoscape that uses adobe flash) not seems to
be options since they include lot of overhead when representing BPEL
processes and state of the deployed process instances.

Recently I started looking into BPEL editor plugin in Eclipse to get the
BPEL diagram generated using it and embedding it with the help of MOVI API
of ORYX on a page with the state of a running process. After getting a basic
understanding of Eclipse plug-in architecture, EMF and GEF I'm unsure
whether it is feasible to integrate that Eclipse functionality with all the
dependencies into BPS.

Please send feedback and further suggestions on my design choice.

Thanks
