Rick,

I do much prefer to look at RDF/N3 rather than RDF/XML...

I have a question about the format of the identifiers used.

If you look at the N3 form that cwm generates

<http://www.Astro.physik.Uni-Goettingen.DE/~hessman/rdf/IAU#He+_ionization_zone>

which I guess comes about because of the "+" character. In itself it's just ugly, and not a real issue, but I've come across cases where certain parsers [*] didn't like the fragments to contain the "." character, or start with a number, so I wonder if we should take care in how we create the fragments, even if my reading of http://gbiv.com/protocols/uri/rfc/rfc3986.html#collected-abnf is that we can use these characters.

[* whatever parser it is that longwell, http://simile.mit.edu/wiki/Longwell, uses]
