Bitte lasst uns doch in diesem Thread bei dem Ausgangstopic bleiben und nicht die Lizenz selbst diskutieren.
Habe nochmal im Wiki etwas weiter gestöbert und das gefunden:
"Each element is examined and only those with an unbroken history chain from version 1 to the most recent ODbL’ed version are marked as “OK”.
Marking elements “OK”
The following simple algorithm seems best for determining which elements are “OK” for inclusion under the ODbL.
Consider a node with 3 versions, and the following possibilities:
If the first version is non-ODbL: all versions are considered “tainted” and are not OK.
If the first version is ODbL, but the subsequent one is not: only the first version is “OK”.
If the first and second versions are ODbL, but the final one is not: the first and second versions are “OK”.
All versions are ODbL: the full element history is “OK”.
In other words, if the earliest edit by a user who hasn’t agreed to the ODbL is version N then the “OK” versions are from 1 to (N-1). If the earliest edit is the first version then no versions of that element are “OK”.
There is the question that automated edits (e.g: those made by bots) may not be deserving of copyright protection, as they are mechanical processes. However, since there isn’t a special flag to indicate these accounts, we can’t do special processing for them.
