Re: [jbpm-dev] JBPM5 Feedback - Task Management
by Adrian Apthorp
Kris,
The sourceforge project page gives the best overview of what has been
implemented:
http://taskcal.sourceforge.net/
I guess the highlights are that it handles the iTip / iMip protocol
allowing invitations to be accepted or declined. The other key feature
is CalDav support. As a side-effect of the CalDav support I found it was
easy to provide WebDav access to process definitions and CardDav
visibility of identities. VEvents can be configured instead of VTodo's
but I really would like to see greater VTodo support in calendaring clients.
There are a number of iCalendar properties where I use process / task
variables as a subsititute for the attributes being available in the
object model of jBPM. The most obvious of these is scheduled start date
(DTSTART). Also, I've found the need to make some additions to iCalendar
to signal transitions on completion of a task as well as the attachment
of forms (such as xForms) for local rendering. This is based very much
on my view of integrating human tasks in to collaboration tools rather
than using standalone task or process management clients.
The implementation approach I've taken is to effectively create a
services layer on jBPM3, which is of course the architectural approach
with jBPM4 and 5. As this has been very much an experimental project a
fair amount of refactoring is needed.
Hope this helps.

JBPM5 Feedback - Task Management
by Adrian Apthorp
I've belatedly seen the proposals for jBPM5 and wonder what the outcome
on the discussion around task management being a separate project is?
In the past I've posted on the use of the various iCalendar standards
for Human Task interaction and built an iCalendar / CalDav adapter
called TaskCal for jBPM 3 and am slowly porting it to jBPM 4.

There was some interest in incorporating these features in to jBPM and
therefore with the advent of jBPM5 and the proposed architecture I would
like to see if there is still interest. I see it rather as a pluggable
interface for a standard Task Management service. As the WS and
iCalendar communities are now getting together this may provide better
future integration opportunities if we can get the semantics aligned.
I also see that some Drools integration work has been done with iCalendar.
