You can always make an excerpt from an ODbL licensed database, which 
will then be an ODbL licensed database in its own right. That's the 
classic "derived database" thing.

While you have to retain attribution saying you derived this from X, in 
every other aspect your new, derived database stands on its own feet, 
and the ODbL applies to it in exactly the same fashion as it did to the 
"original" database.

Therefore, whenever the ODbL says "this database", that could either be 
the full OSM database; or you could make an excerpt from OSM, licensed 
under ODbL, which would then again be "this database" in a smaller context.

Apart from the attribution thing, the excerpted database is not 
different, legally, from the "mother database"; there is nothing in ODbL 
that refers to that mother database in any way.

Frederik
