ah, but how do you know those URIs are id's?
or more specifically, is the following URI an id or a location?
<link rel="something-you-don't-know" href="..." />
You don’t know. Just goes to show once again that Antone was
right all along to rail against abusing atom:link for that
purpose.
Of course you could say that consumers should disregard links
with relationships they don’t understand – which, incidentally,
is equivalent to disambiguating whether atom:link/@href is just
any URI or supposed to be dereferencable. Other than those of us
discussing the threading extension, noone has opined about that
matter.
I'm all for taking the approach of having consumers disregard link
relations they're not familiar with only I would word it differently.
If a consumer comes across a link relation it is not familiar with, the
consumer should treat the href URI as an opaque identifier and not
assume that it is dereferenceable. Otherwise, the definition of the
link relation should unambiguously indicate whether or not the href URI
is or is not dereferenceable.
