I'm inclined to think that the DocumenRef- portion should indicate the library or project name instead of the specific file, i.e. DocumentRef-file instead of DocumentRef-COPYING. This fits better with the example in D.3 Simple license expressions. I'm not sure, but I kind of get that feeling this is supposed to be a reference to an SPDX document that we create, i.e. like the SPDXJSONExample-v2.2.spdx.json, but I don't think anyone has done something like that on CCI.

Looking good, I just would like to use the official repo for download and keep Github as mirror.

LGTM

@valgur Do you have a clue if we can somehow port the package to Windows?

[valgur]

@marxin It's definitely doable, but it will probably require Windows support to be added to the tre package first. Vcpkg has Windows support available (via copious amounts of patching) for both recipes.
