From Bjoern Hassler

The question is two fold:

• How do you let people know what stuff you have and where your stuff is?
• Suppose we're looking at a 'piece of stuff' that you wanted to syndicate content across institutions, then what sort of metadata would you need to exchange in order to be able to build a common repository?

The first question is discussed here resource discovery. For the 2nd question see Using media rss to syndicate and share media.

[edit] 1 Why this is relevant

The ideas described on this page are relevant, because we're using them for two projects:

• CamTV: http://mediaplayer.group.cam.ac.uk
• Steeple podcast portal: http://podcast.steeple.org.uk

The portals contain about 7500 data sets, and we need to have a good syndication standard to be able to share metadata efficiently.
