webprotege relationships form issue/clarification

ganesh
Hi All,

I have an issue in the Relationships form in the classes tab in web protege. This form is displaying values only in certain cases (tested using foaf and fibo ontology). My hunch is, its only displaying object properties. 
Ideally, I wanted to see all relationships (i.e. both data and object properties) for a class in this form when a class is selected.
How do I achieve this in webprotege.Your help is much appreciated.

Thanks!

Ganesh, One way you can see the data properties in Web Protege is to click on the Properties tab at the top (same level as the classes tab). You should see three expandable nodes: owl:TopObjectProperty, owl:TopDataProperty, and Annotation Properties. Click on owl:TopDataProperty and you should see all the data properties defined for the ontology.

Hi Ganesh,

> I have an issue in the Relationships form in the classes tab in web protege. This form is displaying values only in certain cases (tested using foaf and fibo ontology). My hunch is, its only displaying object properties.

It displays data properties as well.  The form will only display values for “values” that are represented in OWL as ObjectSomeValuesFrom, ObjectHasValue, DataSomeValuesFrom and DataHasValue.

This depends upon how the “values” are represented in the ontology.  

Can you provide a specific example (from the foaf ontology) of what you expect to see for a given class?

Cheers,

Matthew

The “Relationships” area of the Classes tab shows those superclasses whose class expression are existential or value restrictions. For data properties, the class expressions would be value restriction axioms, as the screen dump below demonstrates. In the OWL Entity Description view, you see the SubClass axioms involved in the description of class C.
