Nesting of intersectionOf and unionOf

Hi,

 

I need your help on a syntactical problem (if it is one at all).

 

In mapping the data model of ISO 15926-2 to OWL I stumbled over a situation
that I had to solve with a nesting of a unionOf inside an intersectionOf,
and I would like to know whether or not that is allowed. If not, what is the
solution?

 

An example is:

 

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

            <owl:Class rdf:about="#ParticipatingRoleAndDomain"/>  

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

                <owl:Class rdf:about="#ClassOfArrangedIndividual"/>  

                <owl:Class rdf:about="#ClassOfEvent"/>  

                <owl:Class rdf:about="#ClassOfPeriodInTime"/>  

                <owl:Class rdf:about="#IndividualDimension"/>  

                <owl:Class rdf:about="#Property"/>  

                <owl:Class rdf:about="#Status"/>  

            </owl:unionOf>

        </owl:intersectionOf>

 

and another, even more complex:

 

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

            <owl:Class rdf:about="#ClassOfActivity"/>  

            <owl:Class rdf:about="#ClassOfFeature"/>  

            <owl:Class rdf:about="#ClassOfInformationObject"/>  

            <owl:Class rdf:about="#ClassOfOrganization"/>  

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

                <owl:Class rdf:about="#ClassOfInanimatePhysicalObject"/>  

                <owl:Class rdf:about="#ClassOfOrganism"/>  

            </owl:unionOf>

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

                <owl:Class rdf:about="#ClassOfAtom"/>  

                <owl:Class rdf:about="#ClassOfBiologicalMatter"/>  

                <owl:Class rdf:about="#ClassOfCompound"/>  

                <owl:Class rdf:about="#ClassOfCompositeMaterial"/>  

                <owl:Class rdf:about="#ClassOfFunctionalObject"/>  

                <owl:Class rdf:about="#ClassOfInformationPresentation"/>  

                <owl:Class rdf:about="#ClassOfInformationRepresentation"/>  

                <owl:Class rdf:about="#ClassOfMolecule"/>  

                <owl:Class rdf:about="#ClassOfParticulateMaterial"/>  

                <owl:Class rdf:about="#ClassOfSubAtomicParticle"/>  

                <owl:Class rdf:about="#CrystallineStructure"/>  

                <owl:Class rdf:about="#Phase"/>  

            </owl:unionOf>

        </owl:intersectionOf>

 

Please don't bother with the details, I only need confirmation that this is
legal OWL Full.

 

Can you help?

 

Kind regards,

Hans
