Subject Re: Proposition: Twister WS-BPEL engine and Apache Agila
Date Wed, 20 Oct 2004 14:03:54 GMT
I'm going to have a closer look at Agila to see how Twister can fit
here. Is there anything I should look at beside the Subversion
repository?

Twister's engine core is somewhat tied to WS-BPEL. Our approach was a
bit different, we didn't try to build a meta-model or anything too
generic. Our plan was just to extend the engine if other workflow
patterns were needed and not included in BPEL and stick with the specs
for the rest.

Anyway I'll just check Agila and see how Twister and WS-BPEL could be
integrated into it. We could work out a way to stick with your
original plan which, I agree, may be better for a generic workflow
implementation. If you have any question about Twister, just let me
know.

Matthieu.
