Mashed remote contrib: BBC music genres meet last.fm (meets OAuth)

I’m not at the BBC’s 2008 hackday-like-event, Mashed. But here’s a quick hack based on the data the BBC audio and music team have made available. The data that caught my eye was “Genres for set of MusicBrainz Artists” based on editorial data entered for bbc.co.uk/music. This is a simple file:

0039c7ae-e1a7-4a7d-9b49-0cbc716821a6    Rock and Indie
003abc43-e2bb-40e5-a080-3c4b9e56ea63    Classical
0053dbd9-bfbc-4e38-9f08-66a27d914c38    Classic Pop and Rock

It maps a MusicBrainz artist ID (increasingly the defacto open standard for identifying artists, at least in popular western music) to a simple genre label.

I haven’t yet found corresponding pages on the BBC music site for each of these genres.

Since last.fm expose my last 12 month’s most commonly played artists for all to mock, it is quite easy to cross-reference these sources to get a summary of my alleged musical interests.

A commandline ruby script online for now:

Airbag:mashed danbri$ ruby lastfm-genres.rb
Classic Pop and Rock: 13
Rock and Indie: 17
Hip Hop; RnB and Dance Hall: 1
World: 1
Dance and Electronica: 12

It’s a while since I wrote any code, clearly: this should at least be sorted and trimmed to the top 3 or so. We’d need to look at a few people’s profiles to figure out the best approach to summarising someone’s interests, and a little thought is needed for representing this in RDF/FOAF.

Now where I see OAuth fitting into this picture is the “what do we do next” step. OAuth potentially addresses a problem we’ve had in the FOAF scene, whereby FOAF generators and adaptors produce a chunk of markup, but there’s no easy/natural way to post this back into the Web. I’m hoping that blogs and hosting sites will allow external FOAF sources (like this script) to update/augment the FOAF descriptions we host in our existing Web sites and profiles. I sent some notes on this to the OAuth list (albeit to a deafening silence).
