Probably off-topic but: I think as things currently stand in SPDX you would have to use an ad hoc LicenseRef- identifier to express the entirety of copyleft-next-0.3.1 coupled with an amendment that sort of strikes the later versions provision. This issue is also somewhat relevant: https://github.com/spdx/spdx-spec/issues/153 FWIW, built-in 'or-later' clauses are actually common in copyleft open source licenses; the GPL family is the oddity here. (Then again, the whole idea of a downstream license upgradability option is sort of unusual in the bigger scheme of things, but that's another topic.) Richard
