I apologize for not responding earlier - I had extensive travel in May and am only catching up on all email now.

Will is correct that XRI 3.0 does not require the xri: scheme as was required in XRI 2.0. However you are correct that XRI 2.0 has been an OASIS Committee Speciification and does specify the scheme. So I agree that it would be best for it to be formally registered.
As far as I understand, you approve the proposal to publish an RFC reserving the scheme.  Am I right?

On the thread below, I'm not actually sure who is making which statements/comments, and what remains as open issues in terms of preparing the submission. Could you reply back with what information you still need? I will make sure you receive a timely response.
If you agree on having an RFC published, I've already finished writing the appropriate Internet-Draft, which may be processed as an RFC quite quickly, if there is a strong community consensus on its publication.  So, if you finally approbate the intent for publication of the RFC, I'll issue it to IETF Internet-Drafts repository ASAP, to allow its community review and further processing.

Would this IANA Considerations section be enough? Writing a full registration IETF Draft seems a liitle overkill just to register a historical scheme.
(Maybe you meant "Registration Template", not "IANA Considerations section".)

Should it be Historical *now*?  I would understand if XRI 3.0 was already published; but current spec - 2.0 - continues to use it.  Let's make it Permanent for now; later it will be possible to change the category to Historical.  In this case having an RFC won't beexcessive, for a permanent record.
IANA Considerations

URI scheme name.
See above.
URI scheme syntax.
  See [XRISyntax2], Section 2 Syntax.
This and everything below seems OK, modulo some remarks, but please don't mention section names so that it is "See [XRISyntax2], Section 2"
URI scheme semantics.
  See [XRIResolution2] z
Encoding considerations.
  See [XRISyntax2], Section 2.1 Characters and Section 2.3 Transformations.
Section 2.1 only is mostly fine here; Section 2.3 may be omitted, I think.
Intended usage.
  See [XRIResolution2]
Applications and/or protocols that use this URI scheme name.
  See [XRIResolution2]
Interoperability considerations.
  See [XRISyntax2], Section 2.5 Normalization and Comparison.
Maybe, it should be "none"; at least Section 2.5 of Syntax spec. isn't Ok.
Security considerations
  See [XRISyntax2], Section 3 Security and Data Protection Considerations
  Any volunteers?
Change controller.
RFC 4395 requires an Email address of Change Controller.  Which is appropriate?

err, correction.  We're in the process of registering the application/xrd+xml MIME type.  I don't think there are plans to register the xri:// URI scheme, since I believe XRI 3.0 uses standard http URLs.  Drummond (or John, etc) can correct me on that if I'm wrong.
Could you please refer me to the working draft of XRI 3.0 specification?  I can't find it on XRI TC web page.

Anyway, even though the new version is going to deprecate use of 'xri' scheme in URI mapped from XRIs, I think it will necessary to register the scheme for record, maybe in Historical category (http://tools.ietf.org/html/rfc4395#section-4); but for now, while work on XRI 3.0 is still being made, Permanent category should be Ok (RFC 4395 allows transition between categories, so once XRI 3.0 is published, deprecating the scheme, it may be marked as historical as well).

this actually came up on the list very recently and we're in the process of getting it registered. Thanks for the reminder though. :)

Hi all,

Reading the XRI TC specification and seeing the IANA registry for URI schemes (http://www.iana.org/assignments/uri-schemes.html), I've noticed that the 'xri' URI scheme, used when mapping XRIs to URIs/IRIs, isn't yet registered there.  Since there is a claimed use of this scheme name, I think it is necessary to officially register the scheme with IETF/IANA.  This might be done via publishing the Informational RFC.  So what's your opinion?  If you think it is a good idea, I may help as an editor of an appropriate document.
