  • [gentoo-dev] [PATCH] metadata: Add license-mapping.conf for SPDX licens

    From =?UTF-8?q?Micha=C5=82=20G=C3=B3rny?@21:1/5 to All on Sun Nov 13 13:00:01 2022
    Add a file defining mapping of SPDX-2.0 license identifiers to Gentoo
    ebuild licenses. This was originally discussed on Gentoo Bugzilla [1],
    the submitted to the gentoo-dev ml [2].

    The proposed file uses the common key-value format used for
    configuration files. Currently only `spdx-to-ebuild` section is defined
    but other kinds of mapping can be added in the future. As described
    in the top comment, it provides the ability to map SPDX-2.0 license
    identifiers along with the `+` and `WITH` operators to arbitrary
    Gentoo LICENSE strings (including all-of and any-of groups).

    The initial list is taken from cargo-ebuild's license.rs [3],
    courtesy of Leonardo H. Neumann and Georgy Yakovlev. A parser for this
    file format is implemented in pycargoebuild [4].

    These are completely different.

    Different version (SPDX doesn't have 1.3, and we don't have 1.3a).

    Looks like all versions of the FDL are missing?

    Good catch, thanks. I've verified the list against SPDX license list
    and ::gentoo repo now, and removed "W3C-document" and "GPL-3-with- autoconf-exception" that we (no longer?) have.


    +Fair = fairuse

    These are completely different.

    Removed.


    +LPPL-1.3a = LPPL-1.3

    Different version (SPDX doesn't have 1.3, and we don't have 1.3a).

    Removed.

    Looks like all versions of the FDL are missing?

    To be honest, I'm wondering whether copying the list from cargo-ebuild
    is a good idea after all. Perhaps we should just copy the most common
    licenses (i.e. GPLs/BSD/MIT...) that are easy to match, and add other
    licenses as we need them (and verify in the process).

    I've created a PR to track the current status: https://github.com/gentoo/gentoo/pull/28256

    I like the idea.

    If/when we do this:
    - Should this be in a GLEP?
    - It needs pkgcheck support for e.g. invalid entries, duplicates.

    I don't think we need a GLEP, the comment on top should be sufficient to explain how it's supposed to work.
