Hi,

I'm looking to update proj, and also add the new optional datumgrid files. Fortunately, they are meticulous about licenses and they are all annotated for the main package [1], European files [2], North American files [3], and Oceania files [4].

For the main and European datasets, there are some files licensed under the License Ouverte [5]. It's designed to be compatible with CC, OGL, and ODC-BY, but I don't see this one listed on our licensing page. Can someone confirm whether or not the License Ouverte is acceptable in Fedora?

There are also some files that are "Free redistribution is allowed and welcome", which I think might be okay for data and not code, but some clarification there would also be helpful.

FWIW, at least one file with those licenses is packaged in Debian (though I realize we have other concerns.)
