Linked Movie DataBase
Greetings everyone! We are pleased to announce the release of the preview version of the Linked Movie DataBase (LinkedMDB): http://www.linkedmdb.org LinkedMDB aims at publishing the first open linked data dedicated to movies. It currently contains over three million RDF triples with hundreds of thousands of RDF links to other LOD project data sources and movie-related websites. Please check the LinkedMDB website for a description of the data source, a brief overview of the interlinking methodology used, and detailed statistics. We welcome any kind of feedback and comment from the LOD community, either off-list or on the list (if of interest to everyone).

Re: Linked Movie DataBase
Hello! We are pleased to announce the release of the preview version of the Linked Movie DataBase (LinkedMDB): http://www.linkedmdb.org LinkedMDB aims at publishing the first open linked data dedicated to movies. It currently contains over three million RDF triples with hundreds of thousands of RDF links to other LOD project data sources and movie-related websites. Please check the LinkedMDB website for a description of the data source, a brief overview of the interlinking methodology used, and detailed statistics. That's really really exciting! Is the underlying data coming from Freebase, btw? Could your approach be generalised to other data in Freebase? This would also be really neat :-) I'd be also glad to try out ODDLinker! I really wonder how well approximate joins techniques perform. My personal experiments with really ambiguous resource (Jamendo/Musicbrainz) and string-based distances on the different literals attached to the resource were giving quite bad results (33% of false-positives on a 60 resources sample in the best case), so I tried to come up with a different approach exploring linked data as long as we can't take an interlinking decision [1]. It is much slower though, but has the advantage of giving almost no false positives (it dropped down to 0 on a 60 resources sample).

Try: curl -H accept: application/rdf+xml http://data.linkedmdb.org/resource/film/2014 -L Jens, Yes, thanks - so do I. I was trying to get XML RDF by using Firefox with the Tabulator extension, and just expected it to kick in when I went to the data URL. Instead I found myself looking at these text triples. Is there a variant on the URL itself which will return XML RDF? My concern is that XSLT processors should be able to access these linked data resources. XSLT [1.0] only groks XML documents. XSLT just has the document() function in its armoury, and the only information you can give it is a URL: hence the question. (I took this concern to the XSLT list, and the most helpful suggestion I got there was to set up a proxy server which takes URLs, adds an accept header to them, and passes them on. So that's my fallback strategy if I can't put something into the URL to achieve the desired result.) Richard Richard, Please try the Open Data Explorer (esp. Firefox Extension variant [1] ), it works fine with the Linked Movie Database as per some of my twitter micro posts from yesterday [2] . You will also see examples re. other exciting Linked Data additions such as data from the BBC and Southampton Pubs. I even drop a simple mashup in one the links to boot.

The approach could be generalized to data from other subjects in Freebase as well. We chose to focus on movies to be able to provide a high-quality source for a subject that was missing from the LOD cloud.
