    <p>I look for a clearly OWL solution to define a property that is a restriction of another property, similar to an equivalent class. Restriction is based on data properties of either the domain or the range. The restricted property is definitely a subproperty, and, must be inferred.</p> <p>"kid","mother","father" are Person s father.gender = "male" data property mother.gender = "female"</p> <p>(a Male subclassOf Person = equivalent class "gender value "male")</p> <p>father parentOf child ' object relation mother parentOf child ' object relation </p> <p>How to defined fatherOf property, based on parentOf and gender of father? Clearly it is a subproperty of parentOf.</p> <p>However, equivalent object property editor in Protégé does not allow setting a property query, even I do not really see if this can be solved with a property chain. </p> <p>Defining fatherOf as subproperty and (manually) setting fatherOf instead of parentOf is not an option, since this family example is an oversimplified situation of a more complex scenario.</p> <pre><code>&lt;Declaration&gt; &lt;Class IRI="#Person"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;ObjectProperty IRI="#fatherOf"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;ObjectProperty IRI="#parentOf"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;DataProperty IRI="#gender"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;NamedIndividual IRI="#father"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;NamedIndividual IRI="#kid"/&gt; &lt;/Declaration&gt; &lt;Declaration&gt; &lt;NamedIndividual IRI="#mother"/&gt; &lt;/Declaration&gt; &lt;ClassAssertion&gt; &lt;Class IRI="#Person"/&gt; &lt;NamedIndividual IRI="#father"/&gt; &lt;/ClassAssertion&gt; &lt;ClassAssertion&gt; &lt;Class IRI="#Person"/&gt; &lt;NamedIndividual IRI="#kid"/&gt; &lt;/ClassAssertion&gt; &lt;ClassAssertion&gt; &lt;Class IRI="#Person"/&gt; &lt;NamedIndividual IRI="#mother"/&gt; &lt;/ClassAssertion&gt; &lt;ObjectPropertyAssertion&gt; &lt;ObjectProperty IRI="#parentOf"/&gt; &lt;NamedIndividual IRI="#father"/&gt; &lt;NamedIndividual IRI="#kid"/&gt; &lt;/ObjectPropertyAssertion&gt; &lt;ObjectPropertyAssertion&gt; &lt;ObjectProperty IRI="#parentOf"/&gt; &lt;NamedIndividual IRI="#mother"/&gt; &lt;NamedIndividual IRI="#kid"/&gt; &lt;/ObjectPropertyAssertion&gt; &lt;DataPropertyAssertion&gt; &lt;DataProperty IRI="#gender"/&gt; &lt;NamedIndividual IRI="#father"/&gt; &lt;Literal datatypeIRI="&amp;rdf;PlainLiteral"&gt;male&lt;/Literal&gt; &lt;/DataPropertyAssertion&gt; &lt;DataPropertyAssertion&gt; &lt;DataProperty IRI="#gender"/&gt; &lt;NamedIndividual IRI="#mother"/&gt; &lt;Literal datatypeIRI="&amp;rdf;PlainLiteral"&gt;female&lt;/Literal&gt; &lt;/DataPropertyAssertion&gt; &lt;SubObjectPropertyOf&gt; &lt;ObjectProperty IRI="#fatherOf"/&gt; &lt;ObjectProperty IRI="#parentOf"/&gt; &lt;/SubObjectPropertyOf&gt; &lt;DataPropertyDomain&gt; &lt;DataProperty IRI="#gender"/&gt; &lt;Class IRI="#Person"/&gt; &lt;/DataPropertyDomain&gt; &lt;DataPropertyRange&gt; &lt;DataProperty IRI="#gender"/&gt; &lt;Datatype abbreviatedIRI="xsd:string"/&gt; &lt;/DataPropertyRange&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
