Developers and Drools Users Groups.
Greetings:
As both Edson Tirelli and Mark Proctor are presenting two great talks
at October Rules Fest (http://www.OctoberRulesFest.org) this year, I
thought it might be appropriate to let everyone know about the
details. We will have no less than three presentations on CEP (Edson
Tirelli, Paul Vincent of Tibco and Luke Voss ) so it should be a
really great time for techies of this unique little world of rulebased
programmers. Two of the talks have to do with complex implementations
of a rulebased system. Dr. Forgy has promised to discuss (in addition
to his parallel rulebase presentation) his new Tech algorithm that is
10 times faster than Rete 2 or Rete III. In addition we will have
Dr. Forgy (Rete, Rete 2, Rete III, Tech)
Gary Riley (CLIPS inventor)
John Zachman (Enterprise Architecture guru)
Dr. Hafedh Mili (wrote all of the early JRules tutorial manuals)
Mark Proctor (Drools Inventor)
Dr. Richard Hicks (Validation and Verification guru)
Dr. Daniel Levine (One of the Neural Net Godfathers)
Daniel Brookshier (UML -> Rules inventor)
Carole Ann Berlioz-Matignon & Carlos Serrano-Morales (Advisor inventors)
Dr. Jacob Feldman (Open Rules inventor)
Jason Morris (Jess Answer Man)
Luke Voss (former JPL guru)
Remember three things: (1) The Early Bird Discount for the October
Rules Fest expires at the end of July. (2) There are a limited number
of hotel rooms blocked off so, unless you register early, you won't be
guaranteed a hotel room. (3) There are a limited number of seats this
year so unless you register early there is no guarantee that you will
be able to register.
Now, the good stuff: We have been blessed with three things that make
for a GOOD conference. Four things that make for a GREAT conference.
Five things that make for an INSANELY GREAT conference. Six things
that make... I just don't have the words for the sixth and seventh
thing.
1. Great Sponsors
2 Diamond (FICO, No Magic)
2 Gold (PST, KBSC)
1 Silver (Drools)
1 Bronze (BizRules)
2. Great Speakers
see those above
3. Great Meeting Place
The BEST Hotel in Texas, The Adolphus in Dallas
Located in the middle of the restaurant district of Downtown Dallas
4. Great Attendees
Uber-geeks, techies, super-nerds, CTOs, CEOs,
(and all of the other terms that drive Jason up the wall)
Business Analysts, Programmers, Research guys,
Ph.D. Candidates, University Professors
HR guys looking for rulebase engineers?
5. White Papers will be published after the conference in a collection
available either bound, printed format and/or online after the
conference.
6. Videos will be done properly this year by Greg Barton and Chelanie
Israel such that the author will be talking at one corner of the
screen and the presentation on the other side of the screen. (Very
similar to what you see at parlays.com) These will be available after
the conference with a password given at the conference itself or
shortly thereafter.
7. Conference Presentations (PPTs or PDFs) will be available both
during and after the conference with the assigned password for access
during and after the conference.
8. Great Location for food! The conference is located in the middle
of the restaurant district of downtown Dallas and we will have listing
of some of the ones that we know about.

W3C RIF Workshop at RuleML-2009
============================================================================
The W3C Rule Interchange Format (RIF) Working Group (www.w3.org/2005/rules/)
has recently published 6 specifications for the W3C Rule Interchange Format
standard which includes a W3C RIF Production Rules Dialect (RIF-PRD) and a
W3C Basic Logic Dialect (RIF-BLD).
The mission of the Rule Interchange Format (RIF) Working Group is to produce
W3C recommendations for rules interchange languages. Next step will be the
call for implementations of RIF which might be demonstrated at the
RuleML-2009 W3C RIF Workshop. Upcoming future RIF dialects might address a
reaction rules dialect for rule-based complex event processing (CEP).
The new RIF standard is featured at the RuleML 2009 Conference in a W3C RIF
workshop in November 2009 (see http://2009.ruleml.org) with a keynote from
Sandro Hawke (W3C staff representative on the RIF WG) and a tutorial from
Christian de Sainte Marie (ILOG/IBM, co-chair of the RIF WG). There will be
also keynote by Paul Vincent (TIBCO CTO for Business Rules and CEP, EPTS-RA
WG Co-Chair) about "Why Rules Matter in Complex Event Processing... and vice
versa" and a keynote by Donald Chapin (co-chair of the OMG Business Modeling
& Integration Domain Task Force, co-chair OMG SBVR) about "Terminology: The
Semantic Foundation for an Organization's Executable Rules".
About RuleML-2009

Drools Flow Parts 1 & 2
by Mark Proctor
"Drools JBoss Rules 5.0 Flow (Part 1)
/
Every non-trivial business process needs to make complex decisions.
A rule engine is the ideal place for these decisions to happen.
However, it is impractical to invoke a rule engine from a standard
workflow engine. Instead, if we take a rule engine and add workflow
capabilities, we have an ideal tool to model complex business
processes---Drools Flow.
In this two-part article by *Michal Bali*, we'll look at Drools flow
in detail. We'll build a loan approval process and cover the
advanced concepts of a ruleflow like faults, subflows, and decisions."

guvnor's version.txt
by Geoffrey De Smet
Hi,
The guvnor's version.txt is a bit annoying in the development lifecycle.
Try this:
svn update
mvn clean install -DskipTests
svn update
And you get this:
Conflict discovered in
'drools-guvnor/src/main/java/org/drools/guvnor/public/version.txt'.
Select: (p) postpone, (df) diff-full, (e) edit,
(h) help for more options: tf
If it's a build generated file, it should be generated under
drools-guvnor/target/classes/org/drools/guvnor/public/version.txt
or, if it's generated code
drools-guvnor/target/generated-resources/org/drools/guvnor/public/version.txt
and eclipse/intellij must be told to add that dir to their sources

With kind regards,

Loop detection
by Michael Neale
For those that are interested, I thought I would try a variation on
the "tortoise and hare" algorithm to detect cycles in rule firing
patterns in order to "guess" that a infinite loop was happening and
stop it (that would work reasonably well for common cases). I was able
to use a version of it (I call it the "crippled tortoise") - and it
seems to work nicely.
The gist of it is to let the rules spin for a while, after N number of
firings, track another N (ie record the names of rules that fire for N
firings). Then run the cycle detector, see if it ends up with a cycle
- compare the cycle length ( divided by the number of rules in cycle)
with Y and then you have a pretty good idea that a loop is happening
(unless its a fib style recursion, perhaps). I have trouble guessing
what N and Y should be (Y needs to be < N) - I wasn't sure if as the
number of rules increase means that a larger sample is needed to
detect for cycles (as we don't want a false positive).
It seems to work well - certainly an opt in thing - I built it in to
the new execution server code to try it out, as it is an ideal place
you would want some protection like this (to stop wasting CPUs/threads
!).
Just thought people would be interested, and perhaps some have other
ideas (as there are lots of things we can mix in to help with this). I
also looked at using the LeftTuple hashcode, which is fine but only
tracks "key" field changes (so you can see the same hashcode over and
over even though the data is changing), so its not really perfect
either.
