+1; defining the actual link relations should be done outside the webfinger spec, most likely as part of RFC 5988 as Paul mentioned.

The relations are perhaps the trickiest bit of webfinger to standardise, but thankfully 5988 offers guidance; new relations should be defined as specifically as possible, with obvious relation overlap being aggregated into more general identifiers, and eventually being submitted to the registry once sufficient deployment mandates it.

How many of them will we have to define?  Can we at all predict how will Webfinger be used?

We don't know, and no. :-)

We can make educated guesses, but it would be folly to start defining shared, generic terminology before implementation. The XMPP specs are a great example of too much definition stifling actual implementations from growing and evolving.

[walter] from what i’ve seen most webfinger implementations use the “profile-page” and “avatar” link rels to help better identify when subscribing to that user, i.e. after inserting the acct: URI of that user, typically a “confirmation” page is displayed to the user prior to actually subscribe to that user, that shows its avatar and a link to its profile-page. But of course the “describedby” rel may also be used in that context: depending on its type it may suggest whether this is a depiction of that user (more than the “icon” rel) rather than a web page pointing to his profile. Anyway from the webfinger spec perspective it may be good to suggest some specific type of information and update the examples consistently. Then we may discuss further possible values for this, at least their semantics in the webfinger context.
