What do you mean by fields? Keep in mind that databases don't even necessarily involve computers, and the same law still applies. I really think it's best to avoid any RDMS terms. One description for the OSM map database (planet.osm) is a database of georeferenced shapes (including points) with associated data (what the shape represents) and meta-data (time edited, user edited by, etc). I am very tempted to try converting some OSM data from the XML format to a database made by a set of index cards, instead of the normal database made of a few tables in a RDMS "database". > > 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?) > > I'm particularly interested in the application of the ODBL, in OSM's > case, to routes.

You appear to of misquoted me, I don't think I said what you have in your quotation. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
