Disjoint Classes with InfixOWL

[John Thompson]

I have some code where I create some InfixOWL classes and then declare them mutually disjoint.  It looks something like this:

from rdflib.Graph import Graph

from rdflib.Collection import Collection

from FuXi.Syntax.InfixOWL import Class

from RDFClosure.AxiomaticTriples import AllDisjointClasses, members

g = Graph()

Class.factoryGraph = g

# do a loop where I create some InfixOWL Classes and put them in a list called "disjoint_classes"

anode = BNode()

bnode = BNode()

tp_coll = Collection(g, anode, disjoint_classes)

g.add( ( bnode, RDF.type, AllDisjointClasses ) )

g.add( ( bnode, members, anode ) )

Then I do g.serialize(format="pretty-xml").

Now, the problem I have is that it creates a bunch of lists in the OWL XML, like:

 <rdf:Description rdf:nodeID="xRosKEXD963">

    <rdf:first rdf:resource="http://www.example.com/ontology#SomeClass1"/>

    <rdf:rest rdf:parseType="Collection">

      <rdf:Description rdf:about="http://www.example.com/ontology#SomeClass2"/>

      ...

I didn't need all these list items enumerated.  I just wanted the part that says:

<owl:AllDisjointClasses>

    <owl:members rdf:parseType="Collection">

    ...

Why do I get all this extra stuff that I don't need, making my OWL XML file much more huge than it needs to be?

Hey John.

The issue is with the rdflib library you are using FuXi with, not FuXi itself.  How did you install the rdflib library you are using in your code below?

I used easy_install like this:

easy_install -U "rdflib<3a"
