Ron,
In
https://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Jun/0097.html
you raised an issue which was captured in
https://www.w3.org/2000/03/rdf-tracking/#rdfms-xml-base
as
[[[
The xml-base construct could be useful in defining the base of relative
URI's in RDF.
]]]
As recorded in
https://www.w3.org/2001/sw/RDFCore/20020225-f2f/#d-2002-02-25-4
the RDFCore WG has decided that it allow xml:base to affect the conversion
of relative URI refernces to absolute URI references.
In particular it decided:
RFC 2396 states that self document references, such as rdf:about="", are
not relative URI's are thus not subject to being converted to an absolute
URI using xml:base.
It was also noted in section 4.2 of RFC 2396 it states:
However, if the URI reference occurs in a context
that is always intended to result in a new request,
as in the case of HTML's FORM element, then an empty
URI reference represents the base URI of the current
document and should be replaced by that URI when
transformed into a request.
It can be argued that this case should cover RDF's use of URI's.
The WG decided that RDF will convert such references to absolute URI's and
will take in scope xml:base attributes into account in such conversions.
Specifically:
<rdf:RDF xmlns:rdf="https://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:eg="https://example.org/"
xml:base="https://example.org/dir/file">
<eg:type rdf:about="" />
</rdf:RDF>
is equivalent to:
<https://example.org/dir/file>
<https://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<https://example.org/dir/file> .
Please could you respond to this message, copying www-rdf-comments@w3.org
indicating whether this is an acceptable resolution of this issue.
