Change Class and Property Kinds #75

Closed VladimirAlexiev closed 2 months ago

VladimirAlexiev commented 2 months ago

The new style changes class and property kinds as follows:

rdfs:Class -> owl:Class
rdf:Property -> owl:DatatypeProperty (if range is xsd:*), owl:ObjectProperty otherwise

It doesn't mean that we need full OWL reasoning much beyond RDFS. We are just being more specific about the nature of properties.

In UML we would talk about attribute and association. For me:

attribute -> owl:DatatypeProperty
association -> owl:ObjectProperty

However, we do have the case of CIMDatatype and we have compound that in UML is model as attribute. In both cases this should be owl:ObjectProperty. So I think the filtering is correct. It would be good to get a TSV out that we can verify it. We also have the text we can run. All attribute (owl:DatatypeProperty) should start with a small letter - the exception is the Compound that should be owl:Class

" a TSV out that we can verify it": I made a folder "datatypes". datatypes-old is from a previous release (prev dump on "sources") and is a bit bigger. "datatypes-actual" is from the current release. Is that enough, or you also need a list of the object props?
"All attribute (owl:DatatypeProperty) should start with a small letter" . Should I check this, or you trust it's true?
