Yes, moreover. JBossBPM customers need a stable API that they can rely on between version
updates. For details on compatibility see
http://jbpm.dyndns.org/jbpmwiki/index.php?title=APIMission#What_is_expect...
As documented in the wiki the JBossBPM conceptually follows the BPMN specification
http://en.wikipedia.org/wiki/BPMN
Using that spec we created a model which is meant to accommodate the conceptual constructs
from the BPM world
* Event (start, stop, intermediary)
* Gateway (exclusive, inclusive, parallel, complex)
* Task (None, User, Send, Receive, Script, etc)
* SequenceFlow, MessageFlow
* Pools, Swimlanes
* SubProcesses
* CompensationFlow, ExceptionFlow.
* InputSet, OutputSet, IORules
See
http://jbpm.dyndns.org/jbpmwiki/index.php?title=BPMNGlossary for the definition of
terms.
Together with the API we define a Compatibility Test Suite (CTS) that checks whether a BPM
implementation is actually fulfils the SOA-Platform product requirements. At this point
jBPM4 is expected to do so. It is ready when it passes the CTS through the API.
With respect to DroolsFlow, I would expect that you can map your model to the API model
implementing a DialectHandler
http://jbpm.dyndns.org/jbpmwiki/index.php?title=BPMPublicAPI
http://jbpm.dyndns.org/jbpmwiki/index.php?title=APIDialectHandler
For even more detail you can have a look at the API JavaDocs.
http://jbpm.dyndns.org/jbpm-site/jbpm-api/apidocs/index.html
You can have a look at the Airticket GWT Sample Application (to be documented in the wiki)
from the JBossBPM reference implementation (RI). There you find a standard BPMN process
definition created with the Eclipse BPMN Editor from the SOA Tools Package (STP).
Additionaly an API native descriptor that adds BPMN constructs that are not currently
supported by STP. The API Dialect handler includes the STP process definition, builds the
API model and executes it on the RI.
A process modelling tool that supports the full set of BPMN constructs would have very
little externally defined.
In short: A good modelling tool is one that supports a large set of standard constructs
plus proprietary extensions. A DialectHandler should be able to map that to the API model.
A BPM provider that implements the API should be able to execute that model.
