Two new Linked Data sources

There were a couple of interesting announcements in the world of linked data last week.

The first came from Matthew Shorter of the BBC with the announcement of the public beta of their music artists pages. The site pulls in data from MusicBrainz, a community database of music metadata, and from Wikipedia (biographical information), and integrates it with the BBC's own data on when tracks by the artist have been played on BBC programmes. Using HTTP content negotiation you can get an RDF representation of the data. At the moment this doesn't include the play counts, but a message to the W3C public-lod mailing list indicates that the addition of this information is in the pipeline.

Hot on the heels of that came a second announcement on that same list, from Oktie Hassanzadeh & Mariano Consens of the University of Toronto, pointing to their Linked Movie Database project, which draws data from Freebase, Wikipedia and Geonames and provides (automatically generated, using a tool called ODDLinker) links to entries in several other datasets.

Now if someone extends the Southampton Pubs approach to Bristol and Bath, and then triplifies SoccerBase.com, we'll be well on the way to meeting many of my extra-curricular data needs :-)

Comments

I'm excited about the linked movie db.

I can't figure out if they provide any searchable indexes though. How are you supposed to find a movie you are interested in? Download the entire dataset and index it yourself, or do they provide any apis for searchable indexes?

Hi Jonathan,

The Linked Movie DB has a SPARQL endpoint

http://data.linkedmdb.org/sparql

So e.g.

PREFIX movie: http://data.linkedmdb.org/resource/movie/
PREFIX dc: http://purl.org/dc/terms/
SELECT ?title
WHERE {
?film dc:title ?title .
?film movie:director ?person .
?person movie:director_name "Stanley Kubrick" .
}

seems to work.

Thanks for the example PeteJ, I confess I've never seen SPARQL before.
