I agree that most use-cases discussed here have been obviously
substantial, and I agree that the license shouldn't attempt to fix a
definition of substantial in stone. But given that this is such a FAQ,
clearly we should have some guidance available.

Last time this issue was discussed on this list, last autumn, many
people seemed to be in agreement that the current community guideline on
was too example-based and that what's needed was a statement of
principle instead. Michael Collinson proposed the following wording:
OpenStreetMap considers Open Data to be a usefully collected set of
intelligently or machine-made physical observations only. Purely
algorithmic augmentation of data and re-casting of data to use, store or
transmit it in different manners is not part of the data IP. Share Alike
may however apply to physical observations inside the augmented or
re-cast data; in this case the physical observations must be provided to
the public in a commonly used or documented open format as per ODbL
This makes it clear that share-alike isn't triggered just by associating
information (such as user accounts) with the map, but by the addition of
observed physical features (routes being taken by users, perhaps?)
A bunch of people expressed agreement with this at the time, but nobody
has updated the wiki. Should I JFDI? Would anyone object?
