The merge of the IMCEIS-1573 branch effectively duplicates the SWRL rules corresponding to the reification pattern.

For example:

The difference is that the first rule has a label; the second does not.

For OML, a SWRL rule corresponding to the reified object property pattern is not used in OML per se. However, this label could be useful for explanation purposes with OWL2-DL + SWRL reasoners.

Recommend keeping the labelled rule and delete the unlabeled rule.

There is more than duplication of the SWRL rules.
It seems that there are two different representations of the reification pattern.

Here is an example from
https://raw.githubusercontent.com/JPL-IMCE/gov.nasa.jpl.imce.ontologies.public/17561bec3d39ee43bec5b34d48717f14867ecbf4/ontologies/imce.jpl.nasa.gov/www.omg.org/spec/UML/20110701/UML.owl

This rule was introduced as part of the IMCEIS-1573 changes:

    <rdf:Description>
        <rdf:type rdf:resource="&swrl;Imp"/>
        <rdfs:label rdf:datatype="&xsd;string">a_defaultValue_owningParameter reification rule</rdfs:label>
        <swrl:body>
            <rdf:Description>
                <rdf:type rdf:resource="&swrl;AtomList"/>
                <rdf:first>
                    <rdf:Description>
                        <rdf:type rdf:resource="&swrl;IndividualPropertyAtom"/>
                        <swrl:propertyPredicate rdf:resource="&UML;hasA_defaultValue_owningParameterSource"/>
                        <swrl:argument1 rdf:resource="urn:swrl#r"/>
                        <swrl:argument2 rdf:resource="urn:swrl#s"/>
                    </rdf:Description>
                </rdf:first>
                <rdf:rest>
                    <rdf:Description>

                                <swrl:propertyPredicate rdf:resource="&UML;hasA_defaultValue_owningParameterTarget"/>
                                <swrl:argument1 rdf:resource="urn:swrl#r"/>
                                <swrl:argument2 rdf:resource="urn:swrl#t"/>

The following rule was in the original ontology as of version 1.4.0:

The resolution of JPL-IMCE/gov.nasa.jpl.omf.scala.binding.owlapi#39 tackles this problem adequately.
