To whom it may concern,
This request was submitted on 8th December last year, archived at [1],
and effectively replaced the requests sent previously that were
incorrect for various reasons [2].
As the POWDER WG makes its final preparations for a transition request
for W3C Proposed Recommendation status, I realise that there has been no
acknowledgement of the corrected requests, still less a resolution.
The W3C Recommendations Track document that includes the registration
details is available with W3C member access at [3]. The text is not
expected to change before PR transition is requested (apart from
removing diff marks etc.).
Can I ask you to look into the matter please?
Thank you.
Phil Archer
On behalf of the POWDER WG.

To whom it may concern,
This e-mail is sent in line with "How to Register an Internet Media Type
for a W3C Spec" [1] and follows an earlier attempt to follow the IANA
process (see 2, 3).
Having taken advice [4], the W3C POWDER Working Group requests that
consideration be given to registering two Media types for POWDER and
POWDER-S documents.
POWDER: application/powder+xml
==============================
POWDER is a constrained dialect of XML that transports RDF properties
and objects that can be associated with multiple subjects. The media
type details are included in Appendix B of POWDER: Description Resources
[5] which has just completed its (second) Last Call period. The version
cited here includes changes made in response to last call comments and
is not yet published, however, it is the one (or very close to the one)
the working group will present as the Proposed Recommendation. It is
anticipated that this happen within the next 2 weeks. The relevant
section of the Description Resources document is as follows:
Appendix B: POWDER Internet Media Type and Macintosh File Type
The following Media Type has been submitted to the IESG for review,
approval, and registration with IANA

Phil Archer or Matt Womer

How to Register a Media Type for a W3C Specification
Internet Media Type registration, consistency of use
TAG Finding 3 June 2002 (Revised 4 September 2002)
The Internet Media Type / MIME Type for POWDER is "application/powder+xml".
It is recommended that POWDER files use the file extension of .xml (all
lowercase) on all platforms.
It is recommended that POWDER files stored on Macintosh HFS file systems
be given a file type of "TEXT".
Type name:
application
Subtype name:
powder+xml
Required parameters:
None
Optional parameters:
None
Encoding considerations:
Identical to those of "application/xml" as specified in [RFC3023],
section 3.2.
Security considerations:
POWDER is used to make assertions, sometimes socially sensitive, about
web resources. Consumers of POWDER should be aware of the source and
chain of custody of this data. Security considerations for URIs
(Section 7 of RFC 3986 [RFC3986]) and IRIs (Section 8 of RFC 3987
[RFC3987]) apply to the extent that describing resources in POWDER may
prompt consumers to retrieve those resources.
Interoperability considerations:
There are no known interoperability issues.
Published specification:
http://www.w3.org/TR/powder-dr/
Applications which use this media type:
No known applications currently use this media type.
Additional information:
Magic number(s):
As specified for "application/xml" in RFC 3023 [RFC3023], section 3.2.
File extension(s):
.xml
Fragment identifiers:
Identical to that of "application/xml" as described in RFC 3023
[RFC3023], section 5.
Base URI:
As specified in RFC 3023 [RFC3023], section 6.
Macintosh file type code(s):
"TEXT"
Person & email address to contact for further information:
public-powderwg(_at_)w3(_dot_)org
Intended usage:
COMMON
Restrictions on usage:
None
Author/Change controller:
The POWDER specification is a work product of the World Wide Web
Consortium's Protocol for Web Description Resources (POWDER) Working
Group. The W3C has change control over these specifications.
POWDER-S: application/powder-s+xml
==================================
Semantic POWDER, or POWDER-S, is typically generated by performing a
transformation on a POWDER document. Each POWDER-S document is an OWL
ontology from which properties and values can be inferred for a given
resource. In order for inferences to be drawn, however, OWL tools must
implement a semantic extension (defined separately) and it is for this
reason that a new media type is requested, rather than using the
existing RDF/OWL media types. A POWDER-S document is valid RDF/OWL but
is essentially meaningless without the semantic extension.
The media type details are included in Appendix C of POWDER: Description
Resources [5] as follows:
Appendix C: POWDER-S Internet Media Type and Macintosh File Type
The following Media Type has been submitted to the IESG for review,
approval, and registration with IANA
