I understand that dominant opinion is the fact data published on the official website is available to OSM. It's good for the OSM community to be clear about available data.
I would like to ask again about similar cases that I do not understand enough. Assume that TESCO has published the shop data under the CC BY license. Then can I use that data for OSM? I think that data is not available because CC BY license is incompatible with ODbL as OSMF has stated. https://blog.openstreetmap.org/2017/03/17/use-of-cc-by-data/ However, current data published by TESCO under the "misleading" terms is considered as available. It seems unreasonable for me that open data is not available and "misleading" terms data is available. And another case. Many municipalities have published open data under CC BY license. For example, Sacramento County has published the location data of the drainage pumps under CC BY license. https://data-sacramentocounty.opendata.arcgis.com/datasets/37cc6535316e43dbab8e1942ef1d7313_3 Can I use this data for OSM without additional permission? I think that it is not available because it is incompatible with ODbL. However, drainage pumps are managed by Sacramento County, and their names and locations are fact data, so they can be considered as available. Which is correct? After this discussion I would like to make an OSM wiki page as an agreement by the OSM global community. wiki/Available_Data is fine for it? Thanks. muramoto
