There's a few classes of checks we can do.
If the package has a META.yml, it should have a license field. There are
about a dozen legitimate values.
license 'restrictive'
The is an absolute positive match for a disallowed license.
A check covering the above case could safely be added immediately.
Beyond that you have three additional cases...
- The license value exists but is not a known type
- There is no license value in the META.yml
- There is no META.yml
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?
