Didier replies:
I do not want to start a new debate but URLs express locations (Uniform
Resource Location). We could as well use URNs (Uniform Resource Name) to
fetch something by name. I agree with the fact the we could use URIs
(Uniform Resource Identifier). However, you do not *concretely* address the
fact that we may want to fetch a document using more or less complex queries
or if you want *Identifier*. Nonetheless, if I want to express something
like the Oracle SQL query how do I do that with a URI. And *No* I cannot
create a query document and store it on the remote server and then call it
with a simple HTTP GET (using a URL). To replace the actual *wrong* practice
of using HTTP POST to formulate complex document queries, we have to propose
something more solid than etherized nomads.

Now we are on the same wavelength ;-)
