Last Call: OWL 2 and rdf:text primitive datatype

Dear Colleagues,

The OWL Working Group <http://www.w3.org/2007/OWL> has published new Working
Drafts for OWL 2, a language for building Semantic Web ontologies. OWL 2 (a
compatible extension of OWL 1) consists of 13 documents (7 technical, 4
instructional, and 2 group Notes). For descriptions and links to all the
documents, see the OWL 2 Documentation
Roadmap<http://www.w3.org/TR/2009/WD-owl2-overview-20090421/#Documentation_Roadmap>
. This
is a "Last Call" for the technical materials and is an opportunity for the
community to confirm that these documents satisfy requirements for an
ontology language. This is a second Last Call for six of the documents, but
because the changes since the first Last Call
are<http://www.w3.org/2007/OWL/wiki/Changes_Since_December_2008>
limited
in scope, the review period lasts only 21 days. For an introduction to OWL
2, see the four instructional documents: an
overview<http://www.w3.org/TR/2009/WD-owl2-overview-20090421/>
 , primer <http://www.w3.org/TR/2009/WD-owl2-primer-20090421/> , list of new
features <http://www.w3.org/TR/2009/WD-owl2-new-features-20090421/> , and quick
reference <http://www.w3.org/TR/2009/WD-owl2-quick-reference-20090421/> .

In addition, the OWL Working Group <http://www.w3.org/2007/OWL> and the Rule
Interchance Format (RIF) Working Group <http://www.w3.org/2005/rules> have
jointly published a Last Call Working Draft of rdf:text: A Datatype for
Internationalized Text. This datatype, compatible with XML Schema 1.1
Datatypes <http://www.w3.org/TR/xmlschema11-2/> , is used within RIF and OWL
2 to provide support for text in various languages and scripts (identified
by a BCP 47 <http://www.rfc-editor.org/rfc/bcp/bcp47.txt> tag such as "fr"
for French). The document defines the datatype, discusses its relationship
to RDF Plain Literals and the XML Schema string datatype, and specifies
functions (compatible with XPath <http://www.w3.org/TR/xpath-functions/> )
for operating on rdf:text data values. It also discusses how to use this
feature within RDF serializations.
I'd very much appreciate if you could review one or more documents and send
your thoughts and comments to public-owl-comments@w3.org
