[Talk-cz] DIBAVOD Import - which license?

[malenki]

Hi, 

because of disagreeing user Pavel I stumbled over the DIBAVOD import
today.
Although the google translation seemed to show that the DIBAVOD data
seems quite freely licensed it would be nice to have an exact
declaration under which conditions and/or which license the Data was
donated.

It would be kind to add a regarding line here:

Best regards
