[uom-ontology-std] FW: Quantity kinds

["Rijgersberg, Hajo" <Hajo.Rijgersberg@xxxxxx>]

Dear all,

 

Please allow me to make a remark about quantity kinds. Hopefully this discussion is appreciated; it is solely meant to be constructive, with the aim of working together to achieve a high-quality vocabulary. 

 

Let me get to the point. I think we should not define a separate class "quantity kind". "Kind" is an implicit part of the ontology language; classes are meant to model "kinds". We should not deviate from this principle, but exploit it.

 

So not, for example:

 

"length of my table" ---"has quantity kind"---> "length"

"length of my table" ---"is a"---> "quantity"

"length" ---"is a"---> "quantity kind"

 

but:

 

"length of my table" ---"is a"---> "length (quantity)"

"length (quantity)" ---"is a"---> "quantity"

 

Best regards, Hajo Rijgersberg
