Shortened term 

Rather than cantana, which would be the best way to shortcut the name?  Also hat Gott die Welt geliebt, BWV 68? or BWV 68? or Also hat Gott die Welt geliebt?...etc.  I only ask, because I think "cantana" is used a bit too often in the prose.  For example "He later inserted most of them in his third annual cantata cycle, but kept this one and..." Rather than say "this one", I think we need to be a bit more descriptive bearing in mind we speak of other cantatas before this mention.  It would be wrong of us to use the full title, I just wondered if there was a shortened term we could use. Talk
