Re: Literals (Re: model theory for RDF/S)

Patrick,

let's get vocabulary straight:

Just to clarify, when I spoke about weak vs. strong typing, I meant in 
the traditional programming language sense. That is, weak means that the 
type information is carried in the data, and strong means that the 
information is carried by the program. Untyped is sort of off the chart 
in this respect.

In RDF, the schema is the equivalent of a "program", so what you refer 
to as strong is actually weak. Strong typing in RDF would require access 
to the schema where the type information is contained.
