There has been considerable attention paid to the document, which now resides at http://www.w3.org/2007/OWL/wiki/PlainLiteral First, obviously the name has changed from rdf:text to rdf:PlainLiteral (or maybe rdf:O(+> <http://en.wikipedia.org/wiki/Prince_%28musician%29#NPG_and_name_change:_1991.E2.80.931994>). Second, the way that older applications are protected from typed literals with datatype URI rdf:PlainLiteral (http://www.w3.org/TR/rdf-concepts/#section-Graph-Literal) in surface syntaxes is that such literals are illegal in surface syntaxes that also have a syntact for RDF plain literals. Instead of using typed literals with datatype URI rdf:PlainLiteral in, e.g., RDF/XML, applications must use the syntax for plain literals. The needed changes to the WG documents are very slight. As far as I know, only two changes are needed: 1/ Mapping to RDF needs a small change in the forward mapping to effect the above prohibition. 2/ Syntax needs a small change in Section 5.7 to tie the plain literal abbreviated syntax to just rdf:PlainLiteral (and not also to xsd:string). I checked the other documents and didn't see the need for any other changes. My view is that the rdf:PlainLiteral document is now acceptable as far as OWL is concerned, and the WG can vote to publish it or even advance it to CR. peter
