I've just reviewed:
http://gbiv.com/protocols/uri/rev-2002/rfc2396bis.html

Which has recently been "last called" in the IETF URI informal group in
preparation for an IESG last-call request, per:
http://lists.w3.org/Archives/Public/uri/2004Feb/0082.html
I am concerned that the empty component normalization rules may be
troublesome for RDF. My review comments are at:
http://lists.w3.org/Archives/Public/uri/2004Feb/0094.html
The specific example raised is:
[[[[
Section 6.2.2.3:
I'm concerned about empty component normalization:
In RDF usage, the URIs:
http://example.org/
and
http://example.org#
would result in quite distinct resource identifiers, e.g. in:
[[
Triples of the Data Model in N-Triples Format (Sub, Pred, Obj)
<http://www.w3.org/RDF/Validator/run/foo> <http://example.org/prop> "value" .
The original RDF/XML document
1: <?xml version="1.0"?>
2: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
3: xmlns="http://example.org/">
4: <rdf:Description rdf:about="foo">
5: <prop>value</prop>
6: </rdf:Description>
7: </rdf:RDF>
]]
and
[[
Triples of the Data Model in N-Triples Format (Sub, Pred, Obj)
<http://www.w3.org/RDF/Validator/run/foo> <http://example.org#prop> "value" .
The original RDF/XML document
1: <?xml version="1.0"?>
2: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
3: xmlns="http://example.org#">
4: <rdf:Description rdf:about="foo">
5: <prop>value</prop>
6: </rdf:Description>
7: </rdf:RDF>
]]
(RDF triples generated by http://www.w3.org/RDF/Validator/)
Are distinct RDF graphs, even though the URIs are equivalent under the
normalization rules given.
