It's a bit more complicated than that. Use of CC BY data comes down to what is considered attribution "reasonable to the medium or means." OSM provides attribution via a wiki page, http://wiki.openstreetmap.org/wiki/Contributors. No other attribution can be guaranteed. A data provider could consider this inadequate and insist on some more obvious means of attribution (e.g. showing a dynamic attribution in the lower-right like Bing imagery, Mapquest.com, Google imagery, etc). Some of the legwork of confirming this for Australia has been completed already. CC BY data on data.gov.au is okay, they have explicitly said that the CC BY geodata sets can be published under ODbL provided that the attribution is made on the wiki page and the datasets used are listed in the form they want. (http://wiki.openstreetmap.org/wiki/Attribution/data.gov.au_explicit_permiss ion) If you asked the SA DOT the same question and said that data.gov.au views it as acceptable I expect you'd get a yes. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
