+0.5 (adding the circular references issue raised by James), because
some people will use "first" to link to the "live" feed (the one you
subscribe to) and "next" to link to the first archive document and so
on, and some will use "last" and "prev" for the exact same roles…
The given definition is not precise enough.
And wrt "prev", why not "previous"? both could also be registered as
aliases…
- Attribute Value: subscribe
- Description: A stable URI that, when dereferenced, returns a feed
document containing the most recent entries in the feed. This URI is
intended to be subscribed to to keep abreast of changes in the feed.
When different from the URI of the feed document it exists in, it
indicates a URi that should be used for this purpose in place of the
current document's URI.
- Expected display characteristics: Undefined.
- Security considerations: Users should always be informed of the
actual URI they are subscribing to, and subscription should only take
place when it is explicitly requested.
Depends whether @rel="self" was really meant for subscribing and the
spec wording is not precise enough about it; this could then be fixed
with an errata rather than create a new link relation…
Otherwise, +0.5, because it seems to overlap @rel="first" (or "last"?) –
or I missed something…
