Thanks for your feedback on the text.  I’ll be revising the document
accordingly.  Based on comments from you and others, section 4 will likely
undergo heavy restructuring :-)


For the webfinger link relations under, are those that should
go into the existing IANA registry for link relations that was defined by
RFC 5988?  (See  In any
case, registration of link relations can certainly be done as a part of this
specification or it could be done separately.  My own opinion is that it
would be better to define link relations separately, but I’m willing to
follow the group opinion on this one.  Even I don’t know what those relations are :-)

Paul, all,


Thank you for starting addressing this standardization topic within IETF.
Webfinger (and acct:) indeed are being increasingly used and the whole
community would benefit from a well-referenced specification for it.


Here are some comments on the draft:

-          At this stage acct: scheme is needed from a formal point of view
only I guess, so there may not be the need for a full addr-spec support. 

-          I also support the point raised by Mykyta around i18n.  I guess
as we are targeting user addressing more than resource addressing in
general, and given the rise of Internet & social networks in non-ascii
countries it would be important to target a dual URI/IRI scheme (following
the path of the mailto rfc6068bis draft)

-          If no other spec is currently using the acct: scheme then it may
be kept in the webfinger spec, but some existing specifications may be
interested in referencing it as primary/preferred addressing mechanism
(independently from webfinger), e.g. Opensocial,

-          From a more structural point of view it may be useful to better
distinguish the sections related to the scheme from the ones relates to
webfinger. Right now 4.1 and 4.2 are very different in purpose and may
become 4 and 5. Current section 5 could become a subsection of webfinger
(say 5.2)

-          It may also be good to distinguish the behavior on the server
side (creating/exposing the descriptor and its content) from the actual
discovery behavior from the client.

-          Webfinger further uses specific link “rels”, which now are
referenced under domain. I guess some of these rels would need
to be registered as pure tokens (no URI), e.g. “avatar”, “profile-page” and
specified in this spec.

-          Reference 8 can now be updated to rfc6415
