A work that constitutes a Collective > Database will not be considered a Derivative Database. - See more at: > http://opendatacommons.org/licenses/odbl/1-0/#sthash.mDtnZAPO.dpuf > The "this Database in unmodified form" means the particular database that is licensed under ODbL. It can be the OSM database itself, or any database derived from the OSM database that must in itself be licensed under ODbL. So if you did any transformations on the OSM database (ex., converted it into a form suitable for a geocoder), the transformed database is licensed under the ODbL. You can either publish this transformed database or provide the software used to create the transformed database to comply with the license of the source OSM database. Then, this geocoder database can become part of the collective database.
