There is a snapshot of how the license field in META.yml is used at:

   <http://thepierianspring.org/perl/meta>

     1 GPL             # wrong case
     4 GPL version 2   # invalid value
     3 GPLv2           # invalid value
     3 INVALID         # These have a url as a value
     1 LGPL            # wrong case
  3619 NONE            # No license field
     1 Perl            # wrong case
    50 artistic
    26 bsd
    61 gpl
     6 lgpl
    10 open_source
  1497 perl
     2 restrictive
    26 unknown         # invalid value: literal 'unknown'
     3 unrestricted

There should probably be a gpl2 & gpl3. Do we care about case?
