Guided Editor in BRMS / Guvnor Version 5 (Snapshot of 26 June)

by Paul Browne

Folks, For various reasons I'm trying out the Guided Editor for Business Rules in the Guvnor Version 5 (Snapshot of 26 June from Hudson, deployed on JBoss App Server 4.2.2GA). I've created the Package / Category and uploaded a simple fact model (as works in BRMS version 4). I create a new business rule using the guided editor and the screen shows successfully with both 'When' and 'Then' parts.Assume the next question is due to me missing something, but wanted to double check: When I press … [View More]

Can drools continue testing even if one of the conditions fail ?

by DroolUser

Hi, I'm using drools for testing if the few attributes of my MO are not null. I construct the rule in the .drl file in following way : rule "name" when condition1 condition2 condition3 condition4 then consequence end I have observed that the drool engine verifies the conditions line by line (in the sequence they have written). The moment condition fails, control comes back to the calling method. I don't want this. I want the control to … [View More]

Fwd: Special Journal Issue IEEE TKDE: Call for Contributions

by paschke＠mi.fu-berlin.de

Dear Colleagues, Please consider to participate in RuleML-2008 (http://2008.ruleml.org/) which will be in about 3 weeks in Orlando, Florida, collocated with the world largest Business Rules Forum. We have a very interesting program with renowned speakers, a prestigious rules Challenge, a special session + panel about Rule standards, etc. We are also editing a special issue of IEEE TKDE. Please consider to contribute to this issue and forward the open call for contributions (below) to your … [View More]interested colleagues. Thanks, Adrian [ our apologies should you receive this message more than one time ] =========================================================================== CALL FOR Contributions Rule Representation, Interchange and Reasoning in Distributed, Heterogeneous Environments Special Issue of IEEE Transactions on Knowledge and Data Engineering Guest Editors: N. Bassiliades, G. Governatori, A. Paschke, J. Dix =========================================================================== In recent years rule based technologies have enjoyed remarkable adoption in two areas: (1) Business Rule Processing and (2) Web-Centered Reasoning. The first trend is caused by the software development life cycle, which needs to be accelerated at reduced cost. The second trend is related to the Semantic Web and Service-oriented technologies, which aim to turn the Web into a huge repository of cross-referenced, machine-understandable data and processes. For both trends, rules can be used to extract, derive, transform, and integrate information in a platform-independent manner. While early rule engines and environments were complex, expensive to maintain, and not very user friendly, the current generation of rule technology provides enhanced usability, scalability and performance, and is less costly. A general advantage of using rules is that they are usually represented in a platform independent manner, often using XML. This fits well into today's distributed, heterogeneous Web-based system environments. Rules represented in standardized Web formats can be discovered, interchanged and invoked at runtime within and across Web systems, and can be interpreted and executed on any platform. This special issue solicits state-of-the-art approaches, solutions and applications in the area of Rule Representation, Reasoning and Interchange in the context of distributed, (partially) open, heterogeneous environments, such as the Semantic Web, Intelligent Multi-Agent Systems, Event-Driven Architectures and Service-Oriented Computing. We strongly advise that solicited contributions should clearly identify the target class of applications they enable. ======= Topics ======= Original contributions, not currently under review or accepted by another journal, are solicited in relevant areas including (but not limited to) the following: - Rule Representation and Languages * Rule languages for exchanging and processing information through the web * Representation and meta-annotation of rules and rule sets for publication and interchange * Event-driven/action rule languages and models * Rule-based event processing languages and rule-based complex event processing * Modeling of executable rule specifications and tool support * Natural-language processing of rules * Graphical processing, modeling and rendering of rules * Rules in web 2.0, web 3.0, semantic web technologies and web intelligence research - Reasoning and Rule Engines * Execution models, rule engines, and environments * Rule-based (multi-valued) reasoning with and representing uncertain and fuzzy information * Rule-based reasoning with non-monotonic negation, modalities, deontic, temporal, priority, scoped or other rule qualifications * Rule-based default reasoning with default logic, defeasible logic, and answer set programming * Compilation vs. interpretation approaches of rules * Hybrid rule systems - Rule Interchange and Integration * Interchange and refactoring of rule bases in heterogeneous execution environments * Rule-based agility and its role in middleware * Communication between rule based systems using interchange formats and processing / communication middleware * Information integration of external data and domain knowledge into rules * Homogeneous and heterogeneous integration of rules and ontologies * Extraction and reengineering of platform-independent, interchangeable rules and rule models from existing platform-specific resources * Rule interchange standards and related industry interchange formats * Incorporation of rule technology into distributed enterprise application architectures * Interoperation between different rule formats and ontological domain conceptualization * Translation of interchangeable and domain-independent rule formats and rule models into executable technical rule specifications - Rule Engineering and Repositories * Verification and validation of interchanged rule bases in heterogeneous execution environments * Practical solutions tackling the real-world software engineering requirements of rule-based systems in open, distributed environments * Collaborative authoring, modeling and engineering of rule specifications and rule repositories * Management and maintenance of distributed rule bases and rule repositories during their lifecycle - Web Rule Applications * Applications and integration of rules in web standards * Applications of rules in the semantic web and pragmatic web * Applications based on (semantic) web rule standardization or standards-proposing efforts * Applications of rules in e.g. legal reasoning, compliance rules, security, government, security, risk management, trust and proof reasoning, etc. * E-contracting and automated negotiations with rule-based declarative strategies * Specification, execution and management of rule-based policies and electronic contracts * Rule-based software agents and (web) services * Theoretical and/or empirical evaluation of rule-based system performance and scalability ======================= Submission Guidelines ======================= Prospective authors should prepare manuscripts according to the Information for Authors as published in recent issues of the journal or at http://www.computer.org/tkde/.

Enumeration inconsistency in Guvnor

by David Sinclair

When using the business guided editor for building a rule and choosing a field for which an enumeration is defined such as 'Person.age' : ['1=one', '2=two', '3=three'] it will show the description, ie one, two, three. But when configured using a DSL or in the web based decision table, they are shown as 1=one, 2=two, 3=three. Was this done purposely, or is this an omission? I am using the trunk as of a couple of days ago. thanks dave

community skype meetings

by Mark Proctor

Does anyone here like the idea of community skype meetings? We already have irc which is very open, but nothing is ever scheduled, we could schedule a once a month (more if demand needs) skype meeting. What do people think, and what would people like to discuss? Mark

LiteralRestriction NPE

by David Sinclair

Found a NullPointerException when using the verifier module. LiteralRestriction.setValue blows chunks, when the value is null. It sucks that Double.parseDouble doesn't behave the same as Integer.parseInt which handles nulls. java.lang.NullPointerException at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:991) at java.lang.Double.parseDouble(Double.java:510) at org.drools.verifier.components.LiteralRestriction.setValue(LiteralRestriction.java:128) at org.… [View More]

PackageBuilder.java at line 688: public synchronized void addPackage(final Package newPkg) { Package pkg = this.pkgRegistryMap.get( newPkg.getName() ).getPackage(); if pkgRegistryMap is empty as it should probably be initially adding a new package will cause a NPE. This fuction assumes that there is always a package in the packageRegistryMap. I am getting a NPE when I am trying something like: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.… [View More]

Guvnor "this" field

by David Sinclair

Has there been any talk about adding "this" as a field when using a Guided Business Editor in Guvnor? I realize this may be a little more technical for a business user to understand what "this" is, but sometimes it is the only way a join can be performed. thoughts? (sorry if this should have been user list, not dev)
