Team,
Before we decide to put both codebases under the same project or under
separate projects, I would like to ask a couple of clarifying
questions.
First, what is the goal of the Ode project? Is it to develop an
implementation of the BPEL specification, or is it to develop a
process
engine that is based on BPEL, but could support other workflow
patterns as
well, as was suggested in a previous post? While both options have
their own
merits, I am a little bit worried that the later could lead to a
lot of
confusion and wasted efforts, especially if we were to start from two
separate codebases that have very different architectures
underneath. I have
been in the process game long enough to know that not specifying
the process
model upfront -- be it BPEL, BPML, XPDL or WSFL -- can take one
down a path
leading nowhere. A lot of work went into the development of the BPEL
specification, and I respectfully suggest that we do not try to re-
invent
this work here, at least not until we get a working version of the
process
model we pick as a reference point.
Probably all of the above :). We have quite a few different code
bases & use cases here.
Second, if we agree that the goal is to develop an implementation
of the
BPEL specification, I would like us to answer the following
questions. I
understand that some questions have already been answered on this
mailing
list, but summarizing the answers would certainly help.
- Do we want to support BPEL 2.0, BPEL 1.1, or both?
Both
- Do we want to be independent from any specific ESB?
Yes
- Do we want to be independent from any specific J2EE application
server?
Yes
- Do we want to rely on JBI and how does it impact the previous goal?
Not rely no. But optionally reuse it, yes.
- Do we want to have something that we can release now or can we
wait 6 to
12 months?
I'd expect PXE and Sybase to want to be able to release soon - not
6-12 months from now. Certainly as a user of both, I want to use both
in ServiceMix right now; | don't wanna sit on my hands for a year
waiting.
- If we want to release something now, is it ok to have two separate
codebases under the same project?
Yes; lots of other projects do this already. (Agila, Axis, Geronimo etc)
