[protege-discussion] error in defining an enumerated class

[Joe Huang]

re-self:

I found out why: I'd need to create instances for the IDs of every item inside the enumeration class first (i.e. under owl:Thing). Then it works.

Subject: [protege-discussion] error in defining an enumerated class

 

I found that protégé can view enumerated class in OWL, however, its GUI reports error to defining a non-empty enumerated class definition. I don't know why.

(to duplicate the error: create a new class, go to "asserted condition", click on "Necessary & Sufficient" and create a new expression by clicking on "U" and then "{}", type something inside and press enter.) Thanks!

 

An example enumerated class definition:

 

   <owl:Class rdf:ID="AnglePrecisionCode">

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

         <owl:Thing rdf:ID="1000MN">

            <rdfs:label>1000MN</rdfs:label>

            <rdfs:comment>

          Angular precision is expressed to the precision of 1/1000 of a minute.

        </rdfs:comment>

         </owl:Thing>

 

         <owl:Thing rdf:ID="100MN">
