Hi
An other example, your ZIP code or the spelling of your village:
Allowed source for the village name is the shield at the entry of the village.Not allowed is Google Maps / Swiss TopoAllowed information for the ZIP your knowledge, your last received mailMaybe allowed is http://opengeodb.giswiki.org/wiki/OpenGeoDBNot allowed may be other protected “collections” of the data.
Postal code: "your last received mail" - but not the second-to-last mail?
Village name: So my time table for the postal car is not allowed?
Sounds for me with these example too academic - sorry.
With other words: Is there a *prrecise" description which data is allowed and which is not? The information that "copyrighted data" isn't allowed is far too vague as we see for village name and postal code.
