Lars' use case is a produced work[*].  How do we make this clear to
the community and clearly permitted in the license?

Our draft community guidelines on Produced Work[1] say:

"If it was intended for the extraction of the original data, then it
is a database and not a Produced Work. Otherwise it is a Produced
Work. "

Lars' Produced Work is a database, but his database is a list of keys
and values with use totals.  The Produced Work drops the geo location
data and the connectivity data from OSM.  This irreversibly prevents
recreating or extracting the original data.  So by the community
guideline above OSMDoc is a Produced Work.

Best regards,
Richard
