Re: registering formats in the web [uriMediaType-9] [Fwd: Request for MIME media type Application/Personal Tree - prs.]

I didn't realize that there's an expert reviewer in the loop,
even for the personal tree.

They declined my request. Oh well.

Dear Dan,

Our MIME Media Type expert has reviewed your application and had a few comments. 

The registration does not appear to be for a media type in the sense that he 
understands the term. Rather, it is a container for data whose actual type is 
specified externally. We have media types that work the other way around - the type is 
specified locally but the data itself is remote and must be accessed over protocol. 
But he doesn't believe we've ever approved one that works this way, and there has been 
pushback from the IESG and the community on media types that act as containers.

Section 4.1 of RFC 4288 states that media types must function as such. He is not 
convinced this qualifies and he doesn't think it is appropriate for the media types 
reviewer to unilaterally expand the meaning of media types in this way. 

He also does not think the security considerations are spelled out in sufficient 
detail. For example, there are likely to be significant risks associated with the 
ability to tamper with the format specification of a signed object, and all of the 
integrity protection mechanisms provided are optional.

Our MIME Media Type expert is therefore rejecting this registration for the time 
being. He would like, however, to see this brought up for discussion on the media 
types mailing list. You can reach this mailing list by emailing 
If there's a clear community consensus there that this is OK and the IESG sees no 
issue, the MIME Media Type will reconsider the proposal.

After review on the mailing list, if this type gets consensus for registration, please 
resubmit a new application.

Please let us know if you have any questions.

Thank you,

Nicole Rothstein
