namespace naming convention with web applications?

Is there a best practice in defining/naming namespaces for web 
applications? for instance I have a web service application that can be 
accessed by
URL : http://biryani.med.yale.edu:8081/axis/services/GetHAPI
I read that it is best to use URL instead of URN because this allows you 
to point to additional resources like RDF. Is it best practice to create 
a separate directory for each namespace on the server therefore that can 
hold specific resources for a namespace and is there a convention in 
naming in such cases??
for instance, should I do this:
xmlns:nshapi="http://biryani.med.yale.edu:8081/axis/ns/hapi"

I'd appreciate any advice/insight in this....
