Seo -

Yes, this is a bug in the current LOD/RDF interface to Freebase.  I  
believe it is fixed in the upcoming release, which can be previewed at http://rdftest.mqlx.com/ns/en.blade_runner 
..

I checked turtle output with:
rapper -i turtle http://rdftest.mqlx.com/ns/en.blade_runner

Please give this sandbox version of the interface a try.  I'm  
interested in feedback from others on the list as well.

I hope to have the new version in production sometime next week.

Jamie
