Hello! It's me again with another question about a weird license wording on a library. tl;dr; JpGraph's download page[0] says: "JpGraph is released under a dual license. QPL 1.0 (Qt Free License) For non-commercial, open-source or educational use and JpGraph Professional License for commercial use." I don't know what "open-source use" means, but does that wording make this licensing unacceptable for Fedora? Longer story You may recall a thread I started earlier this year[1] about c-pchart and the strange license that led to a contradiction. I've filed an issue with Ampache[2] (a project that uses c-pchart) and they are willing to switch to a different graphing library to help resolve this legal issue. They are considering JpGraph as a replacement, and had asked if it would be acceptable to Fedora. I am not sure since it has the "non-commercial" and "commercial" language in there. Does the "or" in the QPL satisfy our legal requirements (since "open-source" was included in a list with "or"), or does the language about "commercial use" supercede that? It does seem pretty ambiguous to me.
