It doesn't, and it doesn't have to. Only in so far as the *database* has 
been augmented to make the produced work does such information have to 
be released. Any other, non-database input (what you seem to call 
"worthless prettyfing" - I guess that members of the trade might 
disagree!) that becomes part of the Produced Work is not affected by the 

If new information is added at the non-database stage - let's say 
someone prints out a map, paints something over it making the whole 
thing a work of art, then notices a missing road and pencils it in - 
then that is not the making of a derived database and does not have to 
be shared. If the same guy, however, goes back the the data, adds the 
road, and makes a new rendering from it, then it is.
