[Developers] Question about references to wikipedia articles

[Kavitha Srinivas]

Is there a way to get a canonical reference to the current version of  
the wikipedia article for a given guid in freebase?  We are trying to  
establish connections between freebase and dbpedia, and it looks like  
dbpedia has a canonical reference, whereas freebase uses a link to  
the version from which it was created.  Finding equivalences between  
dbpedia and freebase has not been easy, and is prone to errors.  Thanks!
