I think that on the one hand, we want certain details in OSM directly.
As far as licenses go, I understood that CC-BY is easier to comply with
than CC-BY-SA. But when going into the details of licensing things quickly
get blurry for me as well. All I know, is that since you're building a
database, it might make sense to use ODBL.
I guess you are aware of the Overpass API to get live data from OSM to
compare with.

> - provide a de-duplication function to prevent duplicate nodes being

> - provide a mechanism to highlight new charge stations added directly
> into OSM as potential new locations for OCM
> - provide a mechanism to identify changes in geolocation of stations
> in OCM and transferring the new location to the OSM node
> - provide a mechanism to identify stations removed from OCM and to
> remove the charging station attribute, or the entire node, from OSM
