I was at a lecture by Dave Robertson [0] the other day where
he talked about some of the ideas behind one of his current
projects [1]. Particularly relevant was the idea of completely
abandoning any attempts at global semantics and instead working
on making sure the semantics are clear on a local communication
channel (as I understood it).

So maybe that would mean a different meaning for sameAs in
different datasets, and that's just fine as long as the reader
is aware of that and fasions some transformation from their
notion of sameAs to their peer's, mutatis mutandis for other
predicates and classes.

In some ways this is similar to how we use language. If I'm
talking to a computer scientist I'll use a different but 
overlapping sub-language of English than if I'm talking to the
postman. If I'm talking to a non-native English speaker I'll
modify my speech so as to be more easily understood. Around
here, "tea" means "supper" but a short distance to the South
it more likely means a snack with cakes and cucumber sandwiches.

The important thing is a context of communication which modifies
-- and disambiguates meaning. This might be touched on in the
RDF Semantics with the not often mentioned idea of an
interpretation of a graph.

How does this square with the apparent tendency to want to treat
statements as overarching universal truths?

Cheers,
