lacks license grant (contains license but no information of what that might cover)

[jonassmedegaard]

Please include a statement from the copyright holders of what licensing terms they grant for which of the creative works that they own copyright for.

The project ships with a general license, and the package.json contains a license hint. But nowhere is documented who grants said licensing terms to what exactly. On the contrary, some files contain the statement "All rights reserved" which is conventional non-copyleft licensing - i.e. the default when nothing else is stated (and stating that explicitly is superfluous since 30 years!)

Please consider adding an explicit license grant - at minimum similar to jsonld project, but preferably at the top of each copyright-protected file next to (or instead of) that superfluous "All rights reserved" statement which it negates.
