One of the difficult things with the Fedora abbreviations is that
tokens can have spaces in them.  For example, the Apache 2.0 license
in Fedora is called "ASL 2.0".  This makes it really hard to work with
in software.

Likewise, we have historically allowed full expressions through that
contain otherwise forbidden licenses.  For example, many Perl module
packages use the License tag "GPL+ or Artistic" so in a way that
entire expression is treated as a token.

This information is currently captured in this JSON file (not the
original author, but I make use of the file):

    https://github.com/rpminspect/rpminspect-data-fedora/blob/master/licenses/fedora.json

rpminspect's license check uses this data to validate the License tag
in RPM headers based on the rules as they exist in the packaging
guidelines plus the assorted expressions we have historically allowed
through that would not otherwise validate.

*nod*

The string

 'GPL+ or Artistic or MIT'

evaluates license-validate as correct, while rpminspect results that as bad license.
