If you cannot reproduce the Produced Work 100% faithfully from the<br>

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 ODbL.<br>
<br>
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.<br>

Technically I can do that using a pencil as you suggest, or I can do the same thing by processing the produced work into a digital form and applying "pencil marks" using an automated process. But if you allow the latter then you effectively allow reverse engineering of the produced work.<br>
<br> Why should a lead pencil be considered ok, but an electronic pencil not be permitted?<br><br>80n<br><br><br><br><br></div></div>
