Re: documentation/examples of License Ref?

Steve Winslow

Hi Luis, hope you (and others) are staying safe and healthy as well.

Echoing Kyle, "LicenseRef-" is part of the spec syntax and is defined in Appendix IV of the spec. [1] In an actual SPDX document, it would be defined in a corresponding "Other License" section. [2]

In the v2.2 release of the spec (for which a release candidate was circulated this morning), the spec now explicitly clarifies that LicenseRefs can be used in short-form identifiers in source code. [3] REUSE has also implemented this in their spec and described a mechanism for including the corresponding license text directly in a repo.

Hope this helps!

package managers that leverage it as a way for package
authors to express their own license terms.
