Re: app:edited for content/@src

[Peter Keane <pkeane@xxxxxxxxxxxxxxx>]

This seems to me to be related to the perceived need for richer metadata
for media in an atom document. There have been a few threads recently
on that topic on atom-syntax. Yahoo's Media RSS extension came up
(media:content does *not*, in fact, have mtime as one of the attributes,
but that would be an obvious addition for a later rev), as well as
discussion of work on a new Atom media extension, but nothing has gotten
off the ground as yet. Using an "app:edited" attribute strikes me as a
reasonable solution, but I'd prefer to see the more general issue of
media metadata addressed.
