I am. Well, not so much "change", more "clarify".
"Substantial" in EU Database Directive terms can mean quantitative
I agree that extracting a "pubs of Britain" dataset and distributing
it would be quantitatively substantial, so the ODbL Derivative
However, in this case, we have a Collective Database made up of these
1. OSM pubs (Derivative Database)
2. CiderInTheMorning data (presumably proprietary)
3. table mapping OSM ids to CITM ids
The third table is _not_ qualitatively substantial, as the OSM<->CITM
mapping (done by name and locality matching) does not "represent, in
terms of obtaining, verification or presentation, significant
Nor is it quantitatively substantial, because it doesn't contain any
actual OSM data.
Therefore it isn't a Derivative Database.
I think this flows clearly from ODBL but that we could do with a brief
clarification in our guidelines to reassure people this is ok.
