Open Historical Map copyright issues and policy are currently unresolved. The status quo plan is to use the same OdBL license as OSM. Different OHM customers have different license interests, for data contribution, storage, and extraction. This page serves as a record of these various use cases, to help ensure we account for various customer interests and have a thorough discussion of how to resolve user needs.
