would like to port it to the spdx online tools repo wiki, please could you grant me that permission?
Same. I'm also getting
Permission to spdx/spdx-online-tools.wiki.git denied when pushing the changes. I think you should have write access to the repository to be able to add a wiki page.
As far as I can understand, both texts are needed. You can distinguish which license is used in each file from the preamble in each file I guess
and where there are only a gpl and lgpl at the root and nothing else, the license is not clear at all and that happens.
