Hi Robert,

To preface, I'm not a lawyer and your should seek your own independent
legal advice, but as I understand:

1. the department has made a decision to adopt OSM as your data source,
accepting the terms this data is licensed under
2. you will adapt, modify, enhance, correct or extend OSM data with your
gazetted place and road names, which likely creates a Derivative Database
under the ODbL, we'll call this DTP Validated OSM
3. where you make this DTP Validated OSM data available to others, like
your distribution partners or the public via your open data portal, it must
continue to be licensed under the ODbL.
4. The implication for your distribution partners would likely be if they
want to further adapt, enhance, correct or extend your DTP Validated OSM
data, and they then use that adapted data publicly, they must continue to
license their adaptations under the ODbL, ie. the license is viral.
5. There is nothing here preventing these distribution partners using your
DTP Validated OSM data, or making further changes or adaptations to it. If
they don't accept the terms then they don't need to use your data.

One alternative, if you create your data independently of OSM may be to
publish it with only references to OSM, e.g. to OSM object IDs or with
location references eg. OpenLR. If created independently you may be able to
license as you wish.

You could in parallel still publish a full osm derived version of the data
under ODbL for convenience for those who accept the ODbL terms.
