The rule agent is a Peer to Peer component for runtime deployment of
rules/packages/rulebases (well,thats the vision).
In practical terms, its a component you use in any system that requires
rules (and the BRMS/IDE can also use it to deploy).
There will be a deployment descriptor where you declare what rulebases are
(by name) which you then access in code (one line of code), and how the
rulebase is obtained/updated.
Looking at some ideas for deployment config (using file, URI and JGroups
<cache dir="..dir for cold start />
<urlSource url="url to BRMS">
<!-- in this case the rulebase comes from a jgroup, the updates are near
instant, no polling -->
And in the code you access it like:
RuleBase rb = RuleAgent.instance().getRuleBase("myRulebaseFromJGroup");
The rulebase will be updated when the rules are etc.

The International RuleML Symposium
on Rule Interchange and Applications (RuleML-2007)
October 25-26, 2007, Orlando, Florida
The 10th International Business Rules Forum
Call for Papers
Co-located with the 10th International Business Rules Forum, the
International Symposium on Rule Interchange and Applications
(RuleML-2007) is the first symposium devoted to work on practical
distributed rule technologies and rule-based applications which need
language standards for rules operating in the context of, e.g., the
Semantic Web, Intelligent Multi-Agent Systems, Event-Driven
Architectures and Service-Oriented Computing Applications. After a
series of successful RuleML workshops and then conferences (e.g.
http://2006.ruleml.org), this is a new kind of event where the Web Logic
community joins the established, practically oriented Forum of the
Business Rules community (http://www.businessrulesforum.com) to help
cross-fertilizing between Web and Business Logic technology.
The goal of RuleML-2007 is to bring together rule system providers,
representatives of, and participants in, rule standardization efforts
(e.g., RuleML, RIF, PRR, CL, SBVR) and open source rules communities
(e.g., jBoss Rules , Jess, Prova, OO jDrew, Mandarax, XSB, XQuery),
practitioners and technical experts, developers, users, and researchers.
They will be offered an exciting venue to exchange new ideas, practical
developments and experiences on issues related to the engineering,
management, integration, interoperation and interchange of rules in open
distributed environments such as the Web.
A particular focus will be on practical issues such as technical
contributions and show case demonstrations of effective, practical,
deployable rule-based technologies, rule interchange formats and
applications as well as discussions of lessons learned that have to be
taken into account when employing rule-based technologies in
distributed, (partially) open, heterogeneous environments. We also
welcome theoretical contributions that help to build an effective,
practical, and deployable rule standard, improve rule technology,
provide better understanding of the integration and interchange of
rules, and make the current generation of rule engines and rule
technology more usable for advanced Web and Service Oriented Architectures.
Topics of Interest
We invite to share their ideas, results, and experiences: industry
practitioners, rule system providers, technical experts and developers,
rule users, and researchers who are exploring foundations (especially in
the area of system interoperability and rule interchange), are
developing systems and applications, or are using rule-based systems. We
invite submissions related (but not limited to) to one or more of the

reaction rules (e.g., ECA rules, production rules, trigger rules)
- Event-driven/action rule languages and models
- Practical solutions tackling the real-world Software Engineering
requirements of rule-based systems in open, distributed environments
such as the Web
- Modeling of executable rule specifications and tool support (e.g.
development environments, editors, compilers, interpreters,
translators/transformations, rule code generators)
- Execution models, rule engines, and environments
- Compilation vs. interpretation approaches of rules
- Rules interchange standards and related industry interchange formats,
e.g. SBVR, PRR, XBRL,FIX/FPL, FpML, MISMO, ACORD, RuleML, RIF, SWRL, etc.
- Applications and integration of rules in web standards, e.g., semantic
web services (SWS), WS-standards, BPEL, security (e.g. XRML), meta data
processing (e.g. personal information management DC, vCard, FOAF,
- Rule-based software agents and (web) services
- Applications of rules in the Semantic Web and Pragmatic Web (e.g.
negotiation of ontology meaning or communication within a pragmatic context)
- Comparing and advancing the state of current business rules engines
(BRE) and business rules management system (BRMS) tools
- Practical interoperation between different rule formats such as
business rules, decision tables, decision trees, reactive rules,
derivation rules, logical formulas, constraints, association rules,
transformation rules and ontological domain conceptualization including
meaning negotiation and practical use of agreed rules and vocabularies
- Applications based on (Semantic) Web rule standardization or
- Translation of interchangeable and domain-independent rule formats and
rule models into executable technical rule specifications
- Extraction and reengineering of platform-independent, interchangeable
rules and rule models from existing platform-specific resources and

application architectures such as such as Real-Time Enterprise (RTE),
Business Activity Management (BAM), Business Performance Management
(BPM), Business Process Management, Enterprise Workflow Systems,
Database Management Systems or Supply Chain Management Solutions and
related areas such as Service-based Architectures (Service Oriented
Architectures (SOA) / Service Oriented Computing (SOC) / Service
Component Architectures (SCA) ), Semantic Web Services (SWS), IT Service
Management (ITSM) and IT Service Level Management (IT SLM) , and Policy
- Rule-based policies and electronic contracts: their specification,
execution, and management
- Languages for exchanging and processing information through the web,
e.g. common base event, WS-standards, ebXML etc.

temporal, priority, scoped or other rule qualifications
To place emphasis on the practical use of rule technologies in
distributed Web-based environments there will be a RuleML-2007 Challenge
with a focus on rule interoperation and interchange. The challenge
offers participants the chance to demonstrate their commercial and open
source tools, use cases, and applications. Prizes will be awarded to the
two best applications. All accepted demos will be presented in a highly
publicized Challenge Session, first sequentially for the RuleML-2007
plenary, and then in more detail on demand. The two award-winning ones
will be presented in special time slots. Intentionally, this year's
challenge does not define a specific task, data set, application domain,
or technology to be used because the potential applicability of rules is

Kris, looking at the ruleflow stuff (not the core, but the .rf stuff), I
have a suggestion on how to make it more integrated with the ruleset/package
At the moment Ruleflow packages are a seperate entity that is merged into a
RuleBase as needed.
Does anyone have any objections if we add the ability to have ruleflow as
part of a rule Package itself? (thus when that package is added to the
rulebase, all the processes for ruleflow go along with it)? so a
ruleflow.rffile for example becomes just another asset like a drl?
Kris? thoughts? downsides?
No need to change the current API.
It's important that the mailing lists are used correctly, if we allow
user questions to continue on the dev list it creates noise and
confusion and will result in some devs unsubscribing - they purposefuly
subscribe to only the dev list, so they don't have to see user questions.
Btw the sarcasm is really going to make me, and other core devs, want to

Suppose I want to add a business rules in JBRMS.
Now I need facts pattern to be chosen.
I need to select a fact type for that.
But its not showing any option for that.
Please let me know how to get such options.
And also do I need to upload a event model for the application I am trying
to implement rules.
If yes how would be that.
Thanks in Advance.

Just to let you know I am updating the example to use ruleflow (it looks
like one or more rules are wrong too as the "glider" doesn't glide, so
I'll have a look at these also).
Doesn't look particularly taxing so should have it done very soon -
provided the wife doesn't complain that she's not seeing much of me in
the evenings ;-)
With kind regards,
If I have say a set of 10 rules out which 9 fire based on some condition.
However the tenth rule, to which I set a saliency of -1 to make it fire
last, should fire if none of the other 9 rules cause any change to a
particular property of the asserted bean object. Is there some way (command)
using which I can achieve the same from within a DRL file?
