Hi Igor, good point.

My first thought is that if the simplification adds nothing to the data, 
then there is nothing that being added that we could claim ought to be 
shared back to the community, so it should count as unmodified.

Michael's reply to you about the "trivial transformation guideline" of 
30 October agrees with this - in his terms it provides no new "physical 
observations" and the intent of the license is to capture those for 
share-alike, not to extend share-alike to any technique used for storing 
or transmitting the data.

Anyone disagree?

What are the other examples you had in mind? Real-world examples are 
exactly what we need for this.

J.
