for link relations, should there be just one well-defined list of
values with a registry?
Do you have something like
not really, this is HTML5 only.
is more what i had in mind (even though right now it unfortunately
combines a link relation registry and their use in HTTP). i think the
problem is exactly that we have representation-specific and sometimes
conflicting concepts of how to talk about links. i think it would be
useful to take something like mark's draft, remove the HTTP focus,
extend it with more link metadata such as the "method" and "URI
identification" mechanisms, and then define, in separate drafts, how
this could be, for example, represented in HTTP, or in any XML
vocabulary. like i said, this is not a concrete proposal right now, but
something like mark's draft would be a good foundation.
more to the point of your pointer: i am wondering how exactly the wiki
will be managed. is it strictly "add only", and once they're added,
they're in HTML5 for good? is there some feedback or consolidation
phase? now i see that all values say "proposed", which probably means at
some point in time there will be a consolidation and selection phase?
who decides, who selects, and is that selection then hardcoded into
HTML5, like it was in HTML4? what about the overlaps in link semantics
that will necessarily occur because many of these rel values are loosely
defined and probably have a rather specific application background?
and then there seems to be some disconnect with HTML4. this is not a
systematic survey, but HTML4 had "start" and this seems to have been
renamed to "up" (at least that's my understanding) in the current HTML5
draft. is there a list comparing HTML4 and HTML5 relation types? and if
even HTML relation types are not consistent across versions, that's
definitely not the direction i was interested in.
