I would be interested to hear the view of someone wise who knows about these things, because I'm not convinced that ODbL mandates publishing the source (or diff) in every single circumstance. If your interim derived database is a fairly trivial transformation, as I suspect many will be, then your changes aren't quantitatively Substantial; therefore ODbL's provisions may not apply; therefore you may not have to publish the derivative. And yes, as Jonathan Harley says, the diff requirement can also be fulfilled by providing an algorithm. (I don't think that ODbL requires all the components of the algorithm need be open source, FWIW.) I am really really really not a lawyer. cheers Richard -- View this message in context: http://gis.638310.n2.nabble.com/Exception-in-Open-Data-License-Community-Guidelines-for-temporary-file-tp6504201p6530822.html Sent from the Legal Talk mailing list archive at Nabble.com. _______________________________________________ legal-talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/legal-talk
