Usage of rdfs:label

Excuse me, what is the intended usage of rdfs:label?
What the currently deployed software expects from the property value?

By examining RDF, RDF Schema and OWL2 vocabularies, I can see that all
terms contain their local names as their labels. Why? Why was such
a label chosen here? If it is supposed to be a human-readable name for
the resource, then why are there no spaces and the name is written in
camelCase? How is this property indended to be used by applications?

Is there some kind of context for the human readability that the
specification mentions?

Sincerely,
Felicja
