[edit] 1 Description of abstract element: Mediacontent

An enclosure is needed. The suggestion is to use the <media:content> element, with some additional attributes. It's essential to have these values when remotely embedding media. The <media:group> element is also interesting: It collates serveral versions together.

Media information needs to be present in dc fields, because they are key for generating rss/atom. We must not rely on a mechanism that relies on the storage to determine these values.

Note: rss:enclosure (cannot be used because can only occur once), but we may want to include it for the main media item.

<atom:link rel="enclosure" o:bitrate="" o:height="" />

Extensive discussion of enclosures:

• Enclosures in yahoo media, rss, and atom
• Media rss media group element

[edit] 2.1 What if different content items have got different titles?

Needs to be resolved in dublin core/eth/etc.

For syndication, yahoo media offers a solution, see Media rss media group element.

Also see Msc/P/title.
