gist:hasPhysicalLocation

[uscholdm]

gist:hasPhysicalLocation
	a
		owl:ObjectProperty ,
		owl:TransitiveProperty
		;
	rdfs:range gist:Place ;
	skos:definition "Where something is located"^^xsd:string ;
	skos:prefLabel "has physical location"^^xsd:string ;
	.

I propose changing the skos definition to:

• "Relates something to where it is physically located."

ALSO:
I propose adding a subclass restriction to the class, gist:PhysicalIdentifiableItem requiring it to have a physical location. Ie. (gist:hasPhysicalLocation some gist:Place). Perhaps the same for gist:PhysicalSubstance

How about: "Relates something to its physical location"?

The restriction seems good.

Didn't we also want a scope note to the effect that the location could be either permanent (a house) or transient (a car), and that if someone wants to specify a transient relationship they should use a temporal relation?

A definite improvement. Good idea.

We could, in which case, how about:

skos:scopeNote "To model changing locations, create a subclass of TemporalRelation (e.g. EstablishedLocation)" that reifies hasPhysicalLocation^^xsd:string ; 

This might be setting a precedent; we don't usually say how to extend gist, that could get out of hand quickly. But it might make sense in this case. Let's see what people think.

Updated proposal

gist:hasPhysicalLocation
	a
		owl:ObjectProperty ,
		owl:TransitiveProperty
		;
	rdfs:range gist:Place ;
	skos:definition "Relates something to its physical location."^^xsd:string ;
	skos:prefLabel "has physical location"^^xsd:string ;
    skos:scopeNote "To model changing locations, create a subclass of TemporalRelation (e.g. EstablishedLocation) that reifies hasPhysicalLocation"^^xsd:string ; 
	.

[rjyounes]

Oddly, EstablishedLocation sounds to me like the permanent version.

Maybe we don't have to give explicit suggestions. How about just:

"This property includes both temporary (e.g., a car) and permanent (e.g., a house) locations of objects."

Given this was closely related to PR #941, I updated hasPhysicalLocation as part of that PR. It currently is:

gist:hasPhysicalLocation
	a
		owl:ObjectProperty ,
		owl:TransitiveProperty
		;
	rdfs:range gist:Place ;
	skos:definition "Relates something to its physical location."^^xsd:string ;
	skos:prefLabel "has physical location"^^xsd:string ;
	skos:scopeNote "This property does not distinguish between things whose locations are stable and those whose locations change over time; e.g., a fire hydrant vs. a car."^^xsd:string ;
