[webfinger] Registration of a URN for WebFinger Properties

["Paul E. Jones" <[e-mail]>]

Folks,

As you know, properties (both link and subject-specific properties) are 
identified via a URI.  For applications that are defined outside the 
IETF, those organizations are able to define any URI they wish to use.  
For any we might define within the IETF, however, we need something.

In anticipation of having such a need, I think we should create a 
document along the lines of RFC 6755 for WebFinger.  Specifically, we 
would define a URN sub-namespace as:

    urn:ietf:params:webfinger

One such potentially-useful subject-specific properties are "name", 
which would be the the subject's name intended for human consumption.  
If you've queried my WebFinger server, you would know I currently 
advertise my name in English and Chinese.  For the "default" name, the 
URN might be:

    urn:ietf:params:webfinger:name

For language-specific variants, it might be:

    urn:ietf:params:webfinger:name:zh-CN

Defining the various properties and their meaning is an exercise for 
another day, but I hope you see the value in defining the URN 
sub-namespace.

Thoughts?

Paul
