I just looked through older DBpedia releases. I think we started publishing Freebase links in 3.1. Until 3.5, we used URIs like http://rdf.freebase.com/ns/guid.9202a8c04000641f80000000002d1e19 . In 3.6 and 3.7, we used URIs like http://rdf.freebase.com/ns/m/01006r . In 3.8, we will use http://rdf.freebase.com/ns/m.01006r .
All these URIs can be resolved, but they are not the 'canonical' URIs. The ones with the dot also aren't 'canonical': the page http://rdf.freebase.com states that Freebase RDF IDs look like http://rdf.freebase.com/ns/en.steve_martin . On the other hand, the explanations on http://wiki.freebase.com/wiki/Mid and http://wiki.freebase.com/wiki/Id seem to say that mids like '/m/0p_47' are more stable than ids like 'steve_martin', and while all topics have a mid, some don't have an id. So it seems best to use URIs like http://rdf.freebase.com/ns/m.0p_47 . Also, extracting URIs like http://rdf.freebase.com/ns/en.steve_martin would require a bit more coding, but if people (someone at Freebase?) think DBpedia should do that, we could probably add it for 3.9.
