I think the > "EBNF abstract syntax" is the main thing I want to study; > I'm having trouble finding it. Help? We've defined the abstract syntax of R2ML with the help of a UML/MOF model (as proposed by the OMG): http://oxygen.informatik.tu-cottbus.de/R2ML/0.4/metamodel/R2MLv0.4.htm MOF is more abstract (and in some sense more expressive) than ordinary EBNF, and it can be easily mapped to EBNF. But for those who prefer to read EBNF (and I'm afraid this is the majority with a W3C group), we'll make an EBNF for the typed condition language of R2ML by tomorrow. > The first example I see starts with an incorrect namespace > declaration... > > <r2ml:ProductionRule > xmlns:ex="org.drools.examples.TroubleTicketExample" > -- http://oxygen.informatik.tu-cottbus.de/rewerse-i1/?q=node/17 > > The value of a namespace attribute is a URI; "org.drools..." is not.

R2ML rules can be based on an external vocabulary in the form of an RDFS vocabulary or OWL ontology. See the MOF diagram below that defines the possibility of zero or more external vocabularies. We have also a running example where an external vocabulary in the form of the OWL ontology http://oxygen.informatik.tu-cottbus.de/TestVoc.owl is combined with R2ML rules that are being verbalized, see http://oxygen.informatik.tu-cottbus.de/verbalization/index.jsp -Gerd
