[OSM-legal-talk] OdbL: Section 4.6, Does data/methods have to be released on public Produced Work?

[Lars-Daniel Weber]

Hi there,

https://www.wohnlagenkarte.de/ displays location quality of residential areas. Those residential areas haven been produced using OSM data; the polygon area results from at least three surrounding paths and streets.

Since the polygons are derived from OSM data and released in public, I've asked the owner to release the database OR the method to create the database according to ODbL v1.0, section 4.6 - of course without the values of location quality. He denied. He doesn't see a reason to release the data, which the Produced Work is based on.

In my opinion, they've created a Derivative Database using their polygons and they're publishing a Produced Work (the tiles) in public. So section 4.6 applies here - doesn't it?

Sincerely,
Lars-Daniel
