The highly anticipated last.fm/audioscrobbler web services are now live (in beta). For now they seem to consist of XML serializations of a variety of user, artist, tag, group, and forum data, but with far more data than they’ve provided in this form before. As I discuss a couple of music-related projects with friends, I’m sure these’ll come in useful.
I’m a little surprised not to see FOAF profiles listed within that page (instead there’s a less standard XML offering), especially since FOAF is available, but it may be that they’re holding off because RDF is to come soon.
For now, I’m just enjoying the RSS feeds of forums and journals. This lazy web user wasn’t keeping up without them.
