It's great to see you guys releasing this, I'm quite excited. 
I'm also happy that MusicBrainz is going to provide RDF dumps.

Some comments on the RDF you used:

You seem to have created a new URI scheme for bitprints:

AFAIK, this URI scheme is unregistered. Why go to all this 
trouble when these bitprints already have URIs? I think it'd be 
much better to just use:



A schema would be good, since many of the properties aren't 
intuitively obvious (first20?). Let me know if you need help 
with a schema.

<bz:url>http://example.org</bz:url> would be better as 
<rdfs:seeAlso rdf:resource="http://example.org/" />

(The RDFS namespace is at: http://www.w3.org/2000/01/rdf-schema#)

To avoid confusion, properties like bz:album should be called 
bz:albumName (unless you start storing records for albums, like 
MusicBrainz does, in which case you can give them URIs.)

<bz:society>Joe_Frank</bz:society> would be better as 
<bz:society rdf:resource="http://bitzi.com/society/Joe_Frank" />

Otherwise, it looks pretty good. Pretty simple. I assume there 
aren't any more properties in the large dataset than there are 
in http://preview.openbits.org/data/openbits-20010917-sample.rdf

Ouch, 404 on the namespace[1] And your 404 message isn't even 
returned with a 404 status :-(

I've done a bunch of work with the software you're using, the 
ACS, and it's always done 404s correctly in my experience. I'd 
be happy to talk to your whomever to try and straighten out the
