Subject Re: Proposition: Twister WS-BPEL engine and Apache Agila
Date Thu, 21 Oct 2004 18:48:55 GMT
I proposed to combine Twister into Agila to avoid overlapping. I
thought the main goal of Agila was to develop a BPEL engine. Now if
you think it's more appropriate, I wouldn't mind contributing Twister
as itself.

A workflow engine and a web service orchestration engine have a bit of
overlap but are usually used in different use cases, architecture and
offer different features. So if Agila is meant as a workflow engine
more than a web service orchestration solution, it may make sense to
have two separate projects.

What do everybody else think? Geir?
