[to the list this time :-)] This & similar questions have come up numerous times here. I would, BTW, love to see something like the link extensions draft adopted.
Meanwhile, there is: http://search.yahoo.com/mrss/ Which is pretty widely used. In a system I work on at UT Austin, we use Atom quite extensively for a digital asset management and presentation tool. By using the Media RSS extension we got (for free -- it was unintentional) very fancy slideshows with the PicLens Firefox Extension. It also specifies a way to state the MD5 checksum for the linked-to media items. --peter keane On Thu, Jul 10, 2008 at 08:08:38PM +0200, Niklas Lindström wrote: > > Hi! > > I need to supply checksums in Atom entries for resources linked via > content/@src or link/@href.
