I was thinking about the licensing issue some more. Apparently there was a relevant United States court case regarding metadata several years ago in the United States, but it's unclear to me from my brief web search whether this holding would apply to metadata from every nation. Also, I don't know if the underlying statues have changed since the time of that ruling. I think that WMF Legal should be consulted regarding the copyright status of the metadata. Also, I think that the licensing of metadata should be explicitly addressed in the Terms of Use or a similar document which is easily accessible to all contributors to Wikimedia sites.
