Basic rules question
by Abhay B. Chaware
Hi
I am a newbie to rule based applications and trying to get the concept of rules. I have couple of questions about rules to start with, not specifically about Drools though.
Q1 - Should rules be data/model specific or can/should they be generic or both
==========================================================
e.g.
If selected product "TYPE" is "laptop", then category "RAM" should have all "DDR" type items compatible ( selecting items matching certain property )
OR
If selected product is "IBM T42", then category "RAM" should have "512MB DDR" , "1024MB DDR", "2048MB DDR" compatible. ( assigning individual items in rules )
OR
Combination of both
Q2 - How should be the data modeled in above case
==========================================================
e.g.
in product master, each item ( e.g. T40, T42 ) should have a "TYPE" ( e.g. desktop or laptop ) , all items in category "RAM" should have a "TYPE" ( e.g. DDR ) and then control the assignment of RAM options to the PRODUCT through Rule using "DDR" type ?
OR
in product master, each item ( e.g. T40, T42 ) should have a "TYPE" ( e.g. desktop or laptop ) , all items in category "RAM" should have a "compatibleProduct" column ( e.g. desktop or laptop ) and control the assignment of RAM to PRODUCT through "dynamic" rules by selecting all the RAMs by passing the "TYPE" of the product to the database handler.
Am I making my point clear ?
Thanks

How to further shorten the DSL code?
by boy18nj
This is currently I have-
[condition][]There is fire in "{room}"=Fire({room} : room )
[condition][]"{sprinkler}" is in same "{room}" and sprinkler is
"{off}"={sprinkler}: Sprinkler( room == {room}, on == {off} )
[consequence][]Turn on the "{sprinkler}" for "{room}"=modify( {sprinkler}
){setOn(true)}
[condition][]There is a "{room}"={room} : Room( )
[condition][]This is no fire in "{room}"=not Fire( room == {room} )
[condition][]"{sprinkler}" is in same "{room}" and is "{off}"={sprinkler} :
Sprinkler( room == {room}, on == true )
[consequence][]Turn off the "{sprinkler}" for "{room}"=modify( {sprinkler}
){setOn(false)}
Is it possible to further reuse or define the elements and reuse them in
further conditions?

5th International Workshop on Event-Driven Business Process Management (edBPM 2011) collocated with BPM 2011
by Adrian Paschke
Apologies for cross-posting...
---------------------------------------------------------------------
Due to numerous requests we decided to extend the deadline for the
5th International Workshop on Event-Driven Business Process Management,
edBPM 2011 collocated with the BPM 2011 conference to May 27, 2011.
http://icep-edbpm11.fzi.de
=====================================================================
Dear colleagues (with apologies for cross-posting),
you are invited to submit papers for the 5th International Workshop on
Event-Driven Business Process Management to be held alongside the Busines
Process Management Conference on August 29th 2011 in Clermont-Ferrand,
France
<Event-Driven Business Process Management> (EDBPM) is an enhancement of
Business Process Management (BPM) by new concepts of Service Oriented
Architecture (SOA), Event Driven Architecture (EDA), Software as a Service
(SaaS), Business Activity Monitoring (BAM) and Complex Event Processing
(CEP). In this context, BPM means a software platform which provides
companies the ability to model, manage, and optimize these processes for
significant gain. As an independent system, CEP is a parallel running
platform that analyses and processes events. The BPM- and the CEP-platform
correspond via events which are produced by the BPM-workflow engine and by
the - if distributed -- IT services which are associated with the business
process steps. Also events coming from different event sources in different
forms can trigger a business process or influence the execution of the
process or a service, which can result in another event. Even more, the
correlation of these events in a particular context can be treated as a
complex, business level event, relevant for the execution of other business
processes or services closing the loop of insight-to-action. A business
process - arbitrarily fine or coarse grained - can be seen as a service
again and can be "choreographed" with other business processes or services,
even between different enterprises and organisations.
Loosely coupled event-driven architecture for BPM provides important
benefits:
. Responsiveness. Events can occur at any time from any source and processes
respond to them immediately, whenever they happen and wherever they happen.
. Agility. New processes can be modeled, implemented, deployed, and
optimized more quickly in response to changing business requirements.
. Flexibility. Processes can span heterogeneous platforms and programming
languages. Participating applications can be upgraded or changed without
breaking the process model.
TOPICS
Authors are invited to submit novel contributions in the above mentioned
problem domain. Specifically, the relevant topics include, but are not
limited to:
. Event-driven BPM: Concepts
e.g. role of event processing in BPM, business events: types and
representation, vent stream processing in business processes, process event
processing in CEP, data- and event-driven business processes, event and
process interaction patterns
. Design-time CEP and BPM
e.g. modelling modelling events in human-oriented tasks,
semantics/ontologies for event-driven BPM, BPMN and event processing,
interaction modelling of process model and event processing network.
. Run-time CEP and BPM
e.g. event pattern detection, BPEL and event processing, reasoning about
unknown/ similar events
. Applications/ Use use cases for event-driven BPM
e.g. event-driven monitoring/ BAM , event-driven SLA monitoring,
context-aware BPM
The Workshop is planned as a full-day event, including a keynote, paper
presentations, lightning talks, demos, posters, and a moderated, open
discussion with the clear goal of agreeing upon a research roadmap for
event-driven Business Process Management research, by taking into account
new challenges, described earlier.
SUBMISSION
The following types of submission are solicited:
. Long paper submissions, describing substantial contributions of novel
ongoing work. Long papers should be at most 12 pages long.
. Short paper submissions, describing work in progress. These papers should
be at most 6 pages long.
. Use case submissions, describing results from an edBPM use case. These
papers should be at most 4 pages long.
Papers should be submitted in the new LNBIP format
(http://www.springer.com/computer/lncs?SGWID=0-164-7-487211-0). Papers have
to present original research contributions not concurrently submitted
elsewhere. The title page must contain a short abstract, a classification of
the topics covered, preferably using the list of topics above, and an
indication of the submission category (Long Paper/ Short Paper / Use case).
Papers can be uploaded via the workshop page on easychair, the address can
be found on the workshop homepage.
Papers will be published in the postconference proceeding (Springer Verlag)
IMPORTANT DATES
Deadline paper submissions: May 27, 2011 (extended deadline)
Notification of acceptance: June 9, 2011
Camera-ready papers: June 17, 2011
Workshops: August 29, 2011

Unable to create DSL properly?
by boy18nj
I'm trying to create DSL and DSLR out of DRL but so far unsuccessfull with
this small example-
DRL (Working OK)-
#created on: Apr 30, 2011
package com.fire
#list any import classes here.
import com.fire.*;
#declare any global variables here
rule "When there is a fire turn on the sprinkler"
when
#conditions
Fire( $room : room )
$sprinkler : Sprinkler( room == $room, on == false )
then
#actions
modify($sprinkler){setOn(true)};
System.out.println( "Turn on the sprinkler for room " + $room.getName() );
end
DSL-
[condition][]There is fire in "{room}"=Fire( "{room}" : room )
[condition][]"{sprinkler}" is in same "{room}" and sprinkler is
"{off}"="{sprinkler}" : Sprinkler( room == "{room}", on == "{off}" )
[consequence][]Turn on the "{sprinkler}"=modify("{sprinkler}"){setOn(true)};
DSLR- (Error message when compiling mismatched input)
#created on: Apr 30, 2011
package com.fire
expander fireAlarm.dsl
#list any import classes here.
import com.fire.*;
rule "When there is a fire turn on the sprinkler"
when
#conditions
There is fire in "{room}"
"{sprinkler}" is in same "{room}" and sprinkler is "{off}"
then
#actions
Turn on the "{sprinkler}"
log;
end
Can somebody point out what I am doing wrong?
