I am also a very very practical developer who wants to use RDF in some
very specific domains (see previous recent posts for example).

I don't know, I've been looking at Semantic Bank and Sesame 2.0 and it
looks fairly non-abstract to me actually. But I guess it depends on what
you're looking for.

I'm still not following why the "type as metadata about URI" is not

If that is all you have, then you're screwed. But the infoURI thing does
not seem to help much. In this case it would perhaps be better if a "de
facto" standard about ISBN's emerged, e.g. "ISBN's are handled by" so that even Wikipedia would be using the style
instead of its own. That is, if they truly want it to refer to the same
thing as the URI.

I guess this mindset is similar to the Folksonomy ideas around tagging,
where things emerge naturally instead of forcefully. But I may be naive
and unrealistic about it. I don't know.
