Mark,
Your PPT is a great introduction to the world of rule engines and
methods.
My own background is heavily Prolog - for 15 years. I missed seeing
constraint based solutioning - but I guess DROOLS has to leave
somethings to
those old purpose built engines! And besides DROOLS could always
collaborate with a Prolog engine as a close cousin.... ; -)
On to CAM and DROOLS. I have some PPT slides I will share during the
week
once I've cleaned them up for external perusal.
Basically the notion is to use the mechanisms in CAM - that is
essentially a
domain expert agent in XML structures and metadata - and provide an
interface directly in CAM to DROOLS and back again. Then we're adding
the
ability to persist to SQL databases in CAM directly from the XML source
-
using simple XML syntax based assignment instructions.
This should allow people who are not DROOLS experts - to create a
business-centric solution that quickly handles basic ebusiness
transactions - while allowing extended rules to be layered into this -
by
software staff - that handle decreet rules and tests that are beyond the
scope of the base CAM function set.
This gives people the best of both worlds - a purpose built business XML
expert agent - coupled to the extensible DROOLS engine.
Your snippet of DROOLS V3 shows that this is all heading in the right
direction.
We've been experimenting with:
<as:includeScript location="{url/my.drl}"/>
and
<as:executeScript name="{name.drl}" parm="\\xpath\locator\*"/>
as a first pass to provide linkage between the two.
I am definately interested in discussing this with the DROOLS community
-
where CAM can provide a pluggable XML handler toolkit for DROOLS users?
Beyond all this - DROOLS also looks like a good means to implement a
state
machine for BPSS (and JBOSS driven BPM) as envisioned in our BCM
architecture work - but we'll solve one problem at a time here!
I'm a bit allergic to signing up for IRC lists - my daily bandwidth is
severally constrained already - but we can definately look at sharing
some
collaboration resources - possibly a wiki area - where ideas and test
components can be posted..?
Thanks, DW
