Kwalitee Issues


Take a look at the META.yml Spec at (for version 1.4) or (for version 2), and change your META.yml accordingly.

Error: Missing mandatory field, 'abstract' (abstract) [Validation: 1.3];value is an undefined string (abstract) [Validation: 1.3]


Upgrade the bundled version of Module::Install to at least 0.89, but preferably to the most current release. Alternatively, you can switch to another build system / installer that does not suffer from this problem. (ExtUtils::MakeMaker, Module::Build both of which have their own set of problems.)


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.


  • Data::Timeline
  • Data::Timeline::Builder
  • Data::Timeline::Entry
  • Data::Timeline::Formatter
  • Data::Timeline::Formatter::HTML
  • Data::Timeline::Formatter::SimpleTable


Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.


Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
