I've just reviewed: http://gbiv.com/protocols/uri/rev-2002/rfc2396bis.html Modified: 16 February 2004 11:36:15 Size: 167.42 KB (171437 bytes) 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. ]]]] #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
