Should Sea Level be an individual?

[michaelrabenberg]

Here are the relevant triples:

https://www.commoncoreontologies.org/ont00000722 rdf:type owl:Class ;
rdfs:subClassOf http://purl.obolibrary.org/obo/BFO_0000146 ;
rdfs:label "Sea Level"@en ;
http://www.w3.org/2004/02/skos/core#definition "A Fiat Surface that divides the spheroid composed of Earth and its atmosphere at some point that corresponds to the mean level of calm water in the Earth’s oceans."@en ;
https://www.commoncoreontologies.org/ont00001760 "https://www.commoncoreontologies.org/GeospatialOntology"^^xsd:anyURI .

This looks to me like an individual. Can someone give me a reason to think I'm mistaken?

If it's an individual, then I suggest that the following would be a better skos:definition:

The Fiat Surface that divides the spheroid composed of Earth and its atmosphere and that occupies the two-dimensional spatial region that corresponds to the mean level of calm water in the Earth’s oceans.

Also, if it becomes an individual then some other changes to CCO elements that refer to sea level are probably appropriate. That bridge can be crossed if and when we ever arrive at it.

Yes.
