I'm looking for feedback, I'll develop a Semantic Web Drools Module that
will be the subject of my Master Degree Tesis.
The idea is to use Eclipse Modelling Framework (EMF) for prototyping and
follow a Model Driven Architecture (MDA) where the source language is
Semantic of Business Vocabularies and Business Rules (SBVR) and the target
language is Drools DRL.
The mapping could be (PIM level):
- Semantic Web Rule Language (SWRL)
- Ontology Web Language (OWL)
- Rule Interchange Format (RIF)
- REWERSE Rule Markup Language (R2ML)
It could be added to the module at the source UML or Entity Relationship
like models to transform the models into SBVR.
I am studying the drools code and i have seen strange the method
'getNestedConstraintPrefixLenght()' in DRL6Parser.java: If i translate
that function to a regular expression in antlr lexer, it would be "ID? (
(DOT | HASH) ID)* DOT LEFT_PARENT", which have few sense.
of 'nestedConstraint()' describes the expected the expected result as "(
ID ( DOT | HASH ) )* ID DOT LEFT_PAREN constraints RIGHT_PAREN" : it
internally calls to 'getNestedConstraintPrefixLenght()', consumes the
numbers of items retuned by this, calls to 'constrains()' and cosumes a
For me the expected results described in the header of
'nestedConstraint()' do not correspond with the real results.
I deployed drools workbench on tomcat. Guide only explains every thing on
Wildfly or JBOSS EPA cluster
But I am unable to figure out following things:
- How to add new user?
- How to change system properties?
