Draft Response for LC Comment 22 MSM1

[Draft Response for LC Comment 22:] MSM1

Dear Scott,

Thank you for your message
<http://lists.w3.org/Archives/Public/public-owl-comments/2009Jan/0027.html>
on the OWL 2 Web Ontology Language last call drafts.

Thank you for your support of new features in OWL 2.

The OWL WG acknowledges that there are applications where one would like
to use OWL and RIF.  However, the needs of a representation language
have driven the OWL WG to make certain choices in which datatypes are in
OWL 2.  The OWL WG has tried to support a large collection of datatypes,
which may be larger than that supported by RIF.  Applications that want
to use both OWL and RIF can restrict themselves to those datatypes that
ate supported by both OWL and RIF.

The OWL WG had wanted to have a single base type for its numeric types,
namely owl:realPlus.  Several comments, yours included, as well as
implementation experience have resulted in the OWL WG moving to align
with XML Schema, and thus RIF, so that in OWL 2 xsd:decimal, xsd:float,
and xsd:double now have pairwise disjoint value spaces.  As a result of
this change the need for owl:realPlus has disappeared and it has been
removed from OWL 2.  Several OWL 2 documents have been or are being
modified to effect these changes.

The OWL WG has realized that an overview document would be useful and to
that end has produced the Document Overview, with working draft
available at http://www.w3.org/2007/OWL/wiki/Document_Overview

The New Features and Rationale document has gone through a number of
significant edits recently.  The OWL WG hopes that its current version
is more attuned to your needs.  You will, of course, have a chance to
make formal comments on this document when it reaches last-call status.


Please acknowledge receipt of this email to
<mailto:public-owl-comments@w3.org> (replying to this email should
suffice). In your acknowledgment please let us know whether or not you
are satisfied with the working group's response to your comment.

Regards,
