As far as we speak of MIT, SPDX has listed 7 variants while we have 5 short identifiers: No 1:1 mapping * MIT -> either MIT, MIT-CMU or MIT-enna or MIT-feh http://spdx.org/licenses/MIT.html http://spdx.org/licenses/MIT-enna.html http://spdx.org/licenses/MIT-CMU.html http://spdx.org/licenses/MIT-feh.html Most of these are functionally the same, but SPDX has attributed different short identifiers. I think this is mostly because of SPDX having stricter matching guidelines. http://spdx.org/spdx-license-list/matching-guidelines In most cases, we can fix fedora-review checks to choose the proper identifier, in others, display a warning. Not in SPDX: * DMIT (Docbook MIT) -> actually non-free license so not applicable in our use-case https://fedoraproject.org/wiki/Licensing/DMIT 1:1 mapping with SPDX * MIT with advertisement -> 1:1 mapping http://spdx.org/licenses/MIT-advertising.html * MITNFA (MIT +no-false-attribs license ) -> 1:1 mapping http://spdx.org/licenses/MITNFA.html * AML (Apple MIT) -> 1:1 mapping http://spdx.org/licenses/AML.html I prefer our own classification, but I think that the first step would be uniformizing short identifiers even if it means relaxing SPDX guidelines for existing packages. New packages should follow the strict classification unless we manage to get SPDX standards changed, but I feel that this is nitpicking and should not be too hard on packagers for this particular case. > Otherwise we'll have packages with license text that does *not* exist in > SPDX but we're going to be pretending that's the text.
