CR Request Updated

I'm still unsure about exact dates, and am not sure what to do about
Stefano and Beckett's comments.
But this is pretty good-to-go I think, but would appreciate another set
of eyes looking over it.

Summary of Comments

   All last Call comments have been considered, and a notification of
   the fact sent to every commenter. There is a Disposition of Comments
   outlining the status of all current comments at:
   [8]http://www.w3.org/2001/sw/grddl-wg/lc-spec.html. We are either
   waiting for a response from a commenter, or are ongoing engaged with
   the commenter.

   Although we have no normative dependencies on these groups and
   require no formal comments, we requrest comments from all groups
   mentioned in our charter., we have received from the XML Schema WG
   [9]explicit approval and [10]recognition, although no formal
   comments, from [11]DIWG Working Group. Although we do not require
   formal comments from them, we notified both the [12]TAG and the
   [13]Semantic Web Deployment WG when we went to Last Call, and have
   yet to receive any comments from them. The document being sent to CR
   contains the changes that were made to accommodate comments made
   during the Last Call status..

   We propose a publication date of May 1st 2007.

   We propose that the CR period lasts from the date of publication
   until 1 June 2007. Given the brevity of the specification, the
   length of time the specification has been around previous to the
   creation of the WG, and the current active development of several
   implementations, we expect to collect the necessary implementation
   experience in that time.

Preliminary Implementation Report

   There is a preliminary Implementation Report at
   [14]http://www.w3.org/2001/sw/grddl-wg/td/test_results. Note that
   this implementation report shows three implementations in three
   different languages undergoing active development: GRDDL.py
   (Python), Jena (Java), and Raptor (C).

Proposed CR Abstract, Title, and Status Section


   Gleaning Resource Descriptions from Dialects of Languages (GRDDL)


   GRDDL is a mechanism for Gleaning Resource Descriptions from
   Dialects of Languages. This GRDDL specification introduces markup
   based on existing standards for declaring that an XML document
   includes data compatible with the Resource Description Framework
   (RDF) and for linking to algorithms (typically represented in XSLT),
   for extracting this data from the document.

   The markup includes a namespace-qualified attribute for use in
   general-purpose XML documents and a profile-qualified link
   relationship for use in valid XHTML documents. The GRDDL mechanism
   also allows an XML namespace document (or XHTML profile document) to
   declare that every document associated with that namespace (or
   profile) includes gleanable data and for linking to an algorithm for
   gleaning the data.

   A corresponding [15]GRDDL Use Case Working Draft provides motivating
   examples. A [16]GRDDL Primer demonstrates the mechanism on XHTML
   documents which include widely-deployed dialects known as

Exit Criteria

       [38]GRDDL Test Cases. The GRDDL WG will send both [39]GRDDL Test
       Cases and [40]Gleaning Resource Descriptions from Dialects of
       Languages (GRDDL) to PR at the same time, and all other
       ancillary documentation required by the charter will be
       published by then in final form as well.

   Any feedback on implementation and use of this specification would
   be very welcome. To the extent possible, please provide a separate
   email message for each distinct comment.

   A preliminary Implementation Report is available at:

   Note that also the GRDDL WG has produced a [42]Test Cases, a
   [43]Use-Case Scenario, and [44]Standard Library of Transforms, and a
   [45]GRDDL Primer. However, all of these documents currently exist as
   Working Drafts or Notes, and we believe by the time that Gleaning
   Resource Descriptions from Dialects of Languages (GRDDL) reaches
   Proposed Recommendation status, all of these documents will be
   complete and our charter will be fulfilled.
