Missing defined properties/values #6

Closed lavdim closed 6 years ago

lavdim commented 6 years ago

There are some properties/values that are used but not defined:

igrangel commented 6 years ago

Can you point to the specifics lines of code? In case of mat-lbl:DataIdentifier would be named as mat-lbl:dataIdentifier.

annakasprzik commented 6 years ago

permanent, removable, white, mat, reversecoated were all conceived as individuals. Not sure yet if that is the right decision.

lavdim commented 6 years ago

Ok, but in any case IMHO they should be defined. We should have a class to represent those and they should be instantiated as individuals from that class.

annakasprzik commented 6 years ago

Also, two or three Data Identifiers are missing. I have now added the definition for hasDataIdentifier for fun (also renamed it because with me all properties begin with lower case and often with "has" in order to avoid confusion with classes), however, this kind of metamodeling is not possible in OWL. "DataIdentifier" was flawed in the first place since it had a property as domain, so we have to find another solution.

@lavdim: I thought I did that with owl:oneOf? (see classes "Adhesive" and "FaceMaterial")

lavdim commented 6 years ago

I think they should be defined to provide more info on what types/classes they pertain to. Otherwise, we don't know what is a mat-lbl:permanent or a mat-lbl:removable.

see this: https://www.w3.org/TR/2004/REC-owl-guide-20040210/#EnumeratedClasses and/or https://stackoverflow.com/questions/37419182/reference-to-instance-in-owloneof-enumeration .

annakasprzik commented 6 years ago

I don't quite understand -- the two links you posted do not provide more information than that they are instances of the class WineColor, either? And this is what I did by making them instances of the classes Adhesive and FaceMaterial?

lavdim commented 6 years ago

The idea was to define e.g. mat-lbl:permanent as:

mat-lbl:permanent rdf:type owl:NamedIndividual (and/or owl:SomeClass, but maybe Adhesive is enough); 
                                rdfs:label "Permanent"@en ;
                                rdfs:comment "Long lasting material used for the back of physical labels."@en ;
.

mat-lbl:removable ...

...

But let's keep it as it is for now.
