Hi Jack,

sorry but I believe we will need to get hands on your example file to help you further. Off-list is fine.

Hello Irene,

I checked all of the classes and they are all rdf:type owl:Class (they subclass owl:Thing). I checked all of the properties I am using as facets and the items in all of their domains and ranges are rdf:type owl:Class. But no faceted search (I closed and opened the model and refreshed the caches and the swp graphs).

        Jack,

        I don’t believe sub-classing is either an issue or a
        requirement here. Faceted search works over instances of a
        class. Classes are instances of either rdfs:Class or
        owl:Class. So, you need to be faceting over either rdfs:Class
        or owl:Class. And properties to select from as facets would
        need to be associated with these e.g., have owl:Class in their
        domain.

        rather than instances?

        I am trying to build faceted search across standard
        models/repositories. In this case the classes are terminals
        for the repository and contain all the information an instance
        would carry. For example, in the obolibrary DOID, disease
        obo:DOID_9352 is fully populated with content, and the disease
        is unlikely to be subclassed or instantiated.

        My understanding is that these classes can participate in
        faceted search under certain circumstances. First, they have
        to subclassed under one of my classes. Also, for classes to be
        facetable they need to carry properties and look like resources.

        I created namespaces such as the following for Symptoms:

        http://siemens.com/1.0/vocab/biomed-symp
        <http://siemens.com/1.0/vocab/biomed-symp>

        and a prefix for it: biomed-symp. I created a class called
        Symptom and then subclassed several (for the purposes of a
        demo) of the classes in the obolibrary (e.g.,
        obo:SYMP_0000455) to biomed-symp:Symptom. I did the same for
        diseases (etc.). I created facets to bridge the repositories,
        such as biomed-symp:involvesDisease, that I hung off
        biomed-symp:Symptom in the defaultFacets property.

        In the vocabulary, I added these properties (e.g,.
        obo:SYMP_0000455 biomed-symp:involvesDisease obo:DOID_9352).

        Unfortunately this approach isn't working, so I haven't gone
        far enough in one way or another, and figure that you guys
        might know how to do it. Any help would be appreciated as
        faceted search is very important to this project. My faceted
        search in other parts of the project, created the same way but
        on class instances, are working fine.

        What would you use as facets?

            then faceted search on the classes would provide the same
            benefit as faceted search on instances.
