But that just doesn't make any logical sense. If a mash-up isn't a derivative work, then the database might as well be PD (or CC-BY). If produced works aren't protected, then the data isn't protected, because the data is *contained within* the produced works.

Indeed. What's the position of the OSMF and/or the LWG on this one? Can CC-BY-SA data be combined with ODbL data to create a produced work? Or are proprietary produced works allowed, but non-ODbL copylefted produced works disallowed?
