Although this is true for an individual, it is more complicated for a government. There are a few ways that a dataset might be "public domain." - The government could view the material as data which does not qualify for copyright protection in the US. This puts the dataset in the same state as one created by the federal government - there is nothing protected by copyright. - The government could be barred by a statute or regulation from restricting the dataset's use under copyright. The situation here is more complex because they may be copyright holders, but are prevented from acting like they were. I generally accept that when a government makes a statement about releasing data in a particular way that they have the legal ability to do so. Their lawyers presumably know the law applicable to them and have a basis on which to make their statements. > It would be wonderful if you would choose and attach the following > license(s) to the data, and your web site on which they are published. > ODC PDDL (preferred, because it is specific to data), CC-Zero. In the US there are no database rights so CC0 does an adequate job of releasing the rights that do exist. It's when you start to not unconditionally release rights that the CC licenses and ODC licenses differ in the US. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
