OK, I'm glad that the NECC conference has full feeds and all that. But I think the latest push has taken taging to a new level of abstraction. Here's a tag, for example, for one of the sessions: n07s643. This is exactly the sort of thing I predicted would happen. OK, so, what now? The way it should have been done in the first place: each event has an associated URL. Blog posts, etc., can link to (or 'refer to') that URL. In the metadata (ie., the RSS) for an event URL (which now has the same status as a blog post, right?) you can add some event data ('start','finish','location') and indicate event structure ('parent'). Of course, we have to wait for somebody down south to 'invent' it so we can have such a system; when it's just a voice from the north proposing it, the idea doesn't exist.
