may i add a question into faq/use cases:

Q: I want to publish a slippy map/printed map based on OSM data. 
Is it a produced work or derivated database?

A: The slippy map itself is a produced work, however the database you
used has to meet the same requirements as published derived database or a collective
database. In other words, publishing this produced work implies
that you have the same obligations as when publishing the database

or a better wording. which would clarify the odbl-ty of the data.
