I am. Well, not so much "change", more "clarify". "Substantial" in EU Database Directive terms can mean quantitative and/or qualitative. I agree that extracting a "pubs of Britain" dataset and distributing it would be quantitatively substantial, so the ODbL Derivative Database applies. However, in this case, we have a Collective Database made up of these three databases: 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 investment". 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. cheers Richard _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
