Ok, so thus far: we can indicate resources that are related to the given
entry; we can indicate that an entry is a reply to another entry; we can
specify categories to which the entry belongs; but there is currently no
way of indicating the *subject* of the entry.
The best options appear to be:
a. Use dc:subject (appears to be a perfectly acceptable solution to me
assuming that the subject indication is intended for human consumption
<entry>
<dc:subject>The Atom Specification</dc:subject>
</entry>
or...
b. Use link[rel="subject"] (which works if the subject is
identified/described by a dereferenceable URI)
<entry>
<link rel="subject"
href="http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt";
/>
</entry>
I think either approach works. The dc:subject approach is ambiguous.
The link approach requires invention.
Thoughts?
