Allow other open data licences than CC0 in data namespace
Closed, DuplicatePublic

Description

Currently: "All data in the (Wikimedia commons) Data: namespace must be in Public Domain, licensed under Creative Commons Zero (CC0) license. To indicate this, every data page must have "license": "CC0-1.0", which means the data can be used under the CC0 version 1.0, or (at your option) any later version. By editing the data, you agree to the Terms of Use, and you irrevocably agree to release your contribution to the public domain under CC0. At some future time, the list of licenses supported by the Data namespace may be expanded.". per https://www.mediawiki.org/wiki/Help:Map_Data

However it would be practical to be able to use data from Openstreetmap which is under ODbL (https://opendatacommons.org/licenses/odbl/ ) CC-BY-SA (pre 2012) . Also in Finland where i live goverment licence for their open data is CC-BY (including map data) and it would be nice to be able to use that too.

@Zache, you can already use some of the data directly from OSM, without first copying it from OSM to the data namespace. See https://www.mediawiki.org/wiki/Help:Extension:Kartographer#External_data

@Yurik Sure, my use case would be more like if you want to make derivative maps / layers based on OSM . Static historical boundaries could be one real life use case.

Yurik added a comment.Nov 1 2017, 12:14 AM

@Zache, but in that case the historical boundary is not coming from OSM (OSM doesn't support it AFAIK), so why would OSM license matter?

Zache added a comment.Nov 1 2017, 12:15 AM

Second real life use case wast that in WLM we had ~1500 RKY area's which borders are under CC-BY (by default). However for WLM we got borders only to some samples under CC0.

So we made couple demo maps as showcase like this but nothing more.

@Yurik In example there is old borders in OSM version history and there is borders where we know that they will be obsoleted because some reason. In example in Finland there is couple municipal mergers per year which effects to the boundaries. Anyway it doesn't need to be 1:1 reuse but if you are doing derivative work based on OSM data then OSM licence matters.
