The categories were derived from Atom so in dropping it for individual
resources we're going to have to reinvent it (think HTTP headers).

The "templates" category is optional (in that you can reverse engineer it
from the verbs available) but it's definitely a nice to have, and there are
other categories that would be worth standardising too.
It's a non-trivial area though (think official templates vs shared templates
vs private templates) so we'll have to consider whether it's worth doing -
my main concern right now is getting something functional out the door ASAP
(the draft is already well overdue).

Yes, and you can have your own schemes too - e.g. db vs web as distinct from
lax vs nyc.
