No, this information is not available. I fact, the whole system of 
vocabulary import is in need of revision. It is very old and not as 
powerful/convenient as it should be.

Another major issue is that the mapping is non-invertible by design. So 
one cannot find the wiki property/category/page that belongs to some 
external URI used in vocabulary import. One cannot even ensure that this 
mapping is injective (many wiki entities can have the same external 
URI). This is problematic if RDF store backends are used for query 
answering: it is impossible to translate imported URIs back into wiki 
pages for displaying #ask results.

The whole system could use some redesign.
