Dear Jeremy,

Thank you for your comment
     <http://lists.w3.org/Archives/Public/public-owl-comments/2009May/0014.html>
on the OWL 2 Web Ontology Language last call drafts.

Concerning the Manchester Syntax:

The fact that the Working Group is leaving the Manchester Syntax document as a Note and is not planning on turning it into a recommendation does not mean that the Manchester Syntax document is informative as far as the Manchester Syntax is concerned. To the contrary, the Manchester Syntax document is just as normative for the Manchester Syntax as the W3C Team Submissions on Turtle (http://www.w3.org/TeamSubmission/turtle/) and N3 (http://www.w3.org/TeamSubmission/n3/) are for Turtle and N3, and has just as much reason for providing a MIME type as they do. As the Manchester Syntax was already in use (and even in some use as a syntax for entire OWL ontologies), the Working Group felt that there was no downside in having a Working Group note on a Manchester Syntax for OWL 2.

Concerning the new XML Serialization:

The Working Group is firmly convinced that the new XML Serialization will be a net gain for OWL, as it will allow better integration of OWL into the XML tool chain. The Working Group did discuss the pain involved in having another syntax for OWL, but decided that this pain was acceptable, particularly as the Working Group will be providing GRDDL methods for turning documents in the XML Serialization into RDF as part of the implementation activities during the Candidate Recommendation period. This should mean that there is no reduction in the practial interoperability between OWL and RDF, as RDF tools will be able to easily obtain an RDF version of any document using the XML Serialization. This situation is indeed better than before, as the XML Serialization for OWL 1 does not have a GRDDL transform.
