James M Snell:
I would expect anyone who uses RSS 1.0 would be more likely to use
extensions that are well suited to RSS 1.0 and that anyone who uses Atom
1.0 would be more likely to use extensions that are well suited to Atom.
If there is the possibility of cross-over, great, if not, that's ok also.
Fair enough. I was just trying to make things easier for aggregator
developers who are obliged to support both types. However, if age:expires is
better for Atom (and that certainly seems to be the consensus) then that's
the way you should go.
* dcterms:valid has slightly more functionality in that you get to
specify a start date.
I don't necessarily want more functionality. The atom:updated date gives
us a perfectly good start date.
Well if you go with atom:published rather than atom:updated, as Eric
suggested, then that clinches it for me. You have my vote.
Regards
James
