RE: [ebxml-bp] Abela 10/26/2004: Feedback on BPSS Resources

["Jesmond Abela" <jesmonda@maltanet.net>]

Hi,

Following up on the lead as promised! I have been in contact with Tom
Baeyens Founder and Lead Developer, JBoss jBPM. I am attaching his reply
to this email, should anybody be interested to participate.

Regards,



Jesmond

Jesmond,

This definitely has my interest.  Not much docs available yet on the new
architecture.  We are just done with prototyping and we are transforming
this prototype into a first alpha version.

I want to spend some time on this : i propose a one hour teleconference to
describe the new architecture to you and your developers.

https://jboss.webex.com/jboss/onstage/tool/record/viewrecording1.php?EventID=316430010&Rnd=0.4337379236076788
is a jboss jbpm webinar that touches briefly on jbpm 3 at the end.

the sources of the new architecture can be found in cvs.

The gain for us would be that you implement another spec on top of the
jbpm kernel.  This will make jBPM the defacto standard in workflow
engines.  Therefor I want to assist your team if they get stuck.  Will you
be publishing the BPSS the under the LGPL license ?

what about OASIS TC and an open source reference impl for BPSS ?

regards, tom.

Hi Sacha,

Thank you for the information, in fact I had suggested if jBPM could be
used precisely because I have seen the press release you refer to. I have
seen from the minutes of the TC conference call on the 25th October, that
some members had some reservation to use jBPM, and recommended
"ActiveBPEL". I am not aware of technical problems regarding the use of
jBPM,  however I have found this mail on the jBPM developer's forum that
might be interesting.

I am currently following up on this lead..


Best regards,



Jesmond

hi,

i just want to give you all some insight in the ideas we are working out
for the next version of jbpm. your feedback is highly appreciated.
Following 2 issues are the main improvements for the 3.0 version.

layered process modelling
===================
this means that we are finalizing the core process model and its
execution. version 2 already had a core engine that was based on a
directed graph. in version 3 we will separate the directed graph core
engine from the JPDL stuff. This will enable us to implement other models
(such as BPEL, ebXML, XPDL, BPML, ...) on top of the core jbpm engine.

pluggable architecture
=================
We have done extended research to identify and isolate the
responsibilities of workflow management systems (aka perspectives). E.g.
state management, context management, integration, task mgmt, interface,
time based events, ...

State management is the central responsibility. One of the reasons of
existence for workflow mgmt systems is that programming languages are not
well suited to express states. All the other responsibilities are add-ons
that decorate the state management.

The new architecture of jbpm 3 will have state management as the basic
layer. On top of that a number of optional modules can be plugged in. Each
module corresponds to a responsibility. This pluggable architecture will
allow users of jbpm to select only the responsibilities they need. And on
top of that, they will also be able to plug in new modules that extend the
funtionalities of the core engine.

I will make some more information available on our vision of the
responsibilities shortly.

regards, tom.

Hi Jesmond

For a work at University I have played [1] with ebBP 1.01. But it is
incomplete: no join/fork/decision, no business signals, no timers ... And
it is written in Ruby (guess most people expect Java).

There is www.jbpm.org which was just joined into the jboss project. It is
available under the LGPL licence if that matters to you. I think they are
based on Van der Aalst's extended petri nets theories/works. They list
ebXML BPSS on their website. So that might be something to look at.

Regards

Sacha
