Is there a list of 'license:' values in META.yml and what they mean?

Darkwing has asked for the wisdom of the Perl Monks concerning the following question:

Most often, a CPAN module has a license specified in the license: field of file META.yml. For the modules i currently use, i found: apache, perl_5, artistic_2, lgpl, perl, mit.

My question: is there a list of these values and what they mean? I could mostly guess the meaning, of course, but what is perl_5 vs. perl? And finally a list would be better than guessing.

`META.yml` files use the 1.x CPAN Meta spec. The list of licenses supported by this spec is available in CPAN::Meta::History::Meta_1_4. `META.json` files use the 2.0 CPAN Meta spec. The list of licenses supported by this spec is available in CPAN::Meta::Spec.	[reply] [d/l] [select]
