They are not obvious to *me* (nor, I am sure, to my software). Is the
'first', 'last', 'next', etc., to be interpreted by order posted, order
arrived, or some function that considers the timing of the items to which
the item in question is a reply, etc...? Mailers and newsreaders offer
some flexibility in this regard, because the semantics are *not* clear.
Elm, for instance, permits me to sort my messages about a dozen ways,
each of which implies a different semantics of 'Next'...
I would be happy to collect all semantics, and alternative semantics,
of link types, that anyone can propose, ESPECIALLY those (like the above)
where a clear precedent can be gathered from existing RFCs (SMTP, NNTP)
and other standards (ISO book). I will repost to the list when the ideas
trickle down, say within a week, and we'll see then if there is in fact
any coherent 'core' of link types that could be recommended.
