Actually, that may be the most expensive way. As Al Gilman wrote earlier on

The point of URIs is that they creates a single non-colliding space for
"references outside this context" which is not aware of what is a type,
what is an instance, or much of anything else.

I actually countered with an example that in certain contexts you don't
need to identify the resources using a URI... you can use (for example) an
RDF property!

For example, RDF doesn't particularly need a URI scheme to identify media
types, because it's much easier to just invent a predicate relationship
between some node and a literal value, which is to the effect that the
literal value is the unique MIME type for the subject.

But the Bitzi metadata structure may not be set up to store the bitprints
explicitly as RDF literal values that can be unambiguously typed due to a
well defined predicate relationship within a triple. In other words, if it
uses something other than (er... as well as) RDF to store the bitprints,
then it needs to come up with yet more architecture for typing them. The
value of a URI scheme/URN namespace/content type is that you no longer need
to add that mechanism, and hence in this context it may be a lot "cheaper"
to do that than the RDF property based solution.
