Hi Tammo and Rafal, We like to donate BPEL4People extension for ODE and continue development inside ODE. I'll start a separate thread on this. Also it'll be great if we can get HISE incubator project into ODE project and complete the human task implementation also inline with BPEL4People extension. AFAIK, we can move HISE to ODE.
Our plan is to first implement BPEL4People with separate task engine and after that we can consider embeding task engine to ODE itself as described in BPEL4People specification and implement the BPEL4People compilation things in ODE. WDYT? Thanks Milinda 2010/5/21 Tammo van Lessen <[email protected]> > Hi, > > I think it depends on the needs.
