DWH_File

The file "META.yml" is missing from this distribution. META.yml is needed by people maintaining module collections (like CPAN), for people writing installation tools, or just people who want to know some stuff about a distribution before downloading it.

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

The distribution hasn't got a Changelog (named something like m/^chang(es?|log)|history$/i. A Changelog helps people decide if they want to upgrade to a new version.

Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.

This distribution has .pm files with inconsistent versions.

Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

This distribution does not have a license defined in META.yml.

Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.

This distribution does not 'use warnings;' (or its equivalents) in all of its modules. Note that this is not about that your modules actually warn when something bad happens. It's bad if nobody can tell if a module warns or not, without reading the source code of your favorite module that actually enforces warnings. In other words, it's bad if someone feels the need to add 'use warnings' to your modules.

Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

This distribution is not required by another distribution by another author.

Convince / force / bribe another CPAN author to use this distribution.

This distribution does not have a LICENSE or LICENCE file in its root directory.

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