to remix – to adapt the work
Under the following conditions:
attribution – You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
share alike – If you remix, transform, or build upon the material, you must distribute your contributions under the same or compatible license as the original.
The Norwegian Copyright in Literary, Scientific and Artistic Works Act, in section 31 says that works of art and photographic works may be depicted when they are permanently mounted or located in or near a public place or a publicly accessible passage through some place. However, this does not apply when the work is clearly the main subject and the reproduction is exploited commercially. The same section says buildings may be freely depicted.
