Leo, thanks, wiki pagenames are not opaque. [[Sister:Person:X]] is a
"Person:X" page in the Sister: namespace. "Person:X" is the topic, and
Sister is the topic-type, the basic ISO 13250 . The same structure is
applied to subobject names. With performance in mind, these names are
quickly parsed to extract for instance "is-a" relations (through of-Type).
Not sure this gets to your point.    (01)

PatH asked "What language is being used in this example? It is hard to judge
whether this makes sense unless one knows what the semantic rules of the
formalism are." It is hard to answer when I don't know specifically what
you're asking. Perhaps you could provide an example for is-sister-of ?    (02)

Thanks - jmc    (03)

Jim,    (05)

Just an aside: semantics is not equal to ontology. So ways of referring \=
referrents. One typically determines the denotation of the expression to get
at the semantics, which may point initially to the "concepts", which
typically are placeholders for the "referents", i.e., the things in the
world.     (06)
