No.

I'll write something on legal-talk.


I'll reply here because (a) I'm not subscribed to legal-talk and (b) 
this is not a legal issue but one of what the OSMF will choose to do.


"Do the Interstate relations you mention contain information that can 
*not* simply be read from the planet file? I mean - if I removed all the 
bits that a non-agreeing user has added to the relation, would it then 
be trivial to put it back together by e.g. simply doing routing between 
the now dangling segment endpoints?"


Because of redundancy with ref tags, it would be simple to search for 
ref:"I 4" to find everything that belongs in the Interstate 4 relation. 
The only other aspects to the relation are with the choice of roles 
(east/west vs. forward) and tags on the relation.


(By the way, routing probably won't work after the OSMF reverts.)

[OSM-talk] Relations and the license change

[Nathan Edgars II]

Has there been any information as to how the OSMF will handle relations 
when deleting or reverting tainted objects? It is much easier for a 
relation to be tainted than a way; all that needs to be done is the 
splitting of a single member to ruin the entire relation. For example, 
31 of the (non-super non-business) relations for U.S. Interstate 
Highways (network=US:I) were created by a red user and 63 were modified 
by one, which is 18% tainted out of a total of 517.
