[AtomPub] members are listed when GETting a collection, and their identity and metadata about them is exposed through regular atom mechanisms. if members are editable, an "edit" link in the entry will allow clients to update the member entry, by using this link to PUT or DELETE the entry resource. if the entry is a media link entry, then there might be a "edit-media" link in the entry, which will allow clients to update the media resource, by using this link to PUT or DELETE the media resource. this model allows clients to both interact with a media resource's metadata (the "media link entry"), and the media resource itself.
