I am working on a embedded workflow engine at the moment, the core is up and running with about 20 java classes. It uses the concepts in XPDL and underlying WfMC interfaces (type2 form memory).
It would be interesting to know if there is a mapping form LD to XPDL that makes sense ? I think the main area will be the abstract nature of an activity in WfMC world.
I am thinking in a Sakai context that the Workflow service would take IMS-CP from Resources containing LD definitions. It would then instance those, via a live converter (maybe just XSLT) and store the runtime state in a suitable store in the worksite.
Other definitions in other languages (eg XPDL) would be instanced in a similar way. I want to keep it all as lightweight as possible and avoid JBoss at all costs.
