[OSM-talk] Post-Redaction state of data on Geofabrik download server

[Frederik Ramm]

Hi,

     Grex Troxel asked me this, and agreed to making it public:

Yes, I'm sorry for the confusion. I had announced earlier that the 
Geofabrik downloads would remain at a pre-ODbL version for a while and 
ODbL downloads would be offered at a different location in order not to 
have people accidentally process content that is differently licensed.

I did not keep (or plan to keep) pre-redaction (as opposed to pre-ODbL) 
versions of all the extracts though so what you currently see on the 
download server is last night's situation with all redaction bot edits 
in place.

I can see that there's a need for pre-redaction stuff and I'll prepare a 
static set of pre-redaction downloads and upload them to 
download.geofabrik.de/osm-pre-redaction.

This will however take somewhere between 12 and 24 hours.

In case somebody is confused: "pre-redaction" is the data from before 
the redaction bot started, i.e. early July. "pre-ODbL" (and 
post-redaction) is where we are now because our data is legally still 
CC-BY-SA even after the bot is through. "post-ODbL" is where we will be 
after OSMF have announced that from now on the data is released under 
ODbL, something that will happen in the next couple of months. Or weeks. 
Or hours. Who knows ;)

Bye
Frederik
