RE: Use of same name with different case considered harmful

RDF uses URIs as identifiers, and URIs are strictly case sensitive so it shouldn’t matter.
But  some systems (particularly Windows based) ignore case in filenames that are often mapped to URIs …
It’s not a rule, and could be argued to be pandering, but another view is that it is merely an avoidable risk.
Is also likely to trip people up from time to time in documentation.

The LOCN vocabulary includes a number of terms in which an RDF property has the same name as an RDF Class, differing only in case [1], e.g.
locn:geometry vs. locn:Geometry
locn:address vs locn:Address

While strictly OK, this is generally considered risky, since some processing environments fail to distinguish between tokens on the basis of case alone.
Modifying the vocabulary to avoid this might be a helpful revision, e.g.

locn:geometry --> locn:hasGeometry
locn:address --> locn:hasAddress

Just a lurker here, but this post got my interest
We use this pattern sometimes (in other contexts)
I thought RDF was case sensitive, is there some tooling that you are aware of, that is not?
