Right.  Each database lives at a separate URL endpoint, rather than the
Z39.50 model of having a server which can maintain multiple databases.
The reason being that URLs have practically zero cost, compared to
dedicated servers listening on ports.
And that there's nothing preventing implementers from writing a server
which maintains multiple databases ... you just reference them by the URL.

Zoom is an excellent abstraction for object oriented IR, but doesn't
define a protocol itself ... it's just an OO interface to Z39.50 (and more
recently to SRW in some implementations)
