DaveB's <a
href="http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Jun/0099.html">proposal</a>
for issue faq-html-compliance was approved and this issue closed</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-17.html#T09-53-10">log</a>
The WG agreed the following resolution of rdfs-isDefinedBy-semantics and
closed this issue:
<blockquote>
<p>This property indicates a resource which contains information about
the subject. Often, this property is used to indicate the source of the
subject uriref, where its owner specifies its intended meaning. The
subject node of this property can be any uriref, and the value may be
any document or resource; the usage is not restricted to a particular
form or schema</p>
</blockquote>
</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-17.html#T10-52-09">log</a>
The WG agreed to drop the requirement from M&S that "In RDF, each
predicate used in a statement must be identified with exactly one
namespace, or schema." because there is no concept of a namespace or
schema in the RDF model.</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-17.html#T10-56-18">log</a>
The WG agreed to modify the exisiting RDF and RDFS namespaces rather than
create new ones and seek implementor feedback on this decision. The WG
agreed this closes issue rdf-namespace-change.</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-17.html#T10-59-07">log</a>
The WG agreed to defer schema document editorial issues to the editor and
close rdfs-editorial.</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-17.html#T15-50-48">log</a>
The WG agreed to define a computable function on URIREFs which will
return one of two values, light or dark. A statement with a property
whose URIREF is mapped to dark by this function is invisible to the model
theory; it has no semantics. The WG agreed to postpone issue rdf-contexts
to a future WG.</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-18.html#T11-17-58">log</a>
The WG decided to send a short email to www-rdf-interest and others in
the RDF community soliciting input on the tidy/untidy decision.</li>
<li><a
href="http://ilrt.org/discovery/chatlogs/rdfcore/2002-06-18.html#T12-22-02">log</a>
The WG decided that the RDF graph syntax does not allow isolated nodes in
the graph.</li>
<li><a

normalization rules</p>

similar). Lbase will be published as a w3c note.</li>
