Moving my Meta Modules

Some time ago I wrote Test-YAML-Meta. At the time the name was given as a compliment to Test-YAML-Valid, which validates YAML files in terms of the formatting, rather than the data. Test-YAML-Meta took that a step further and validated the content data for META.yml files included with CPAN distributions against the evolving CPAN META Specification.

With the release of Parse-CPAN-Meta I wrote Test-CPAN-Meta, which dropped the sometimes complex dependency of the more verbose YAML parsers, for the one that was specifically aimed at CPAN META.yml files. With the emergence of JSON, there was a move to encourage authors to release META.json files too. Although considered a subset of the full YAML specification, JSON has a much better defined structure that has more complete parser support. Coinciding with this move was the desire by David Golden to properly define a specification for the CPAN Meta files. It was agreed that v2.0 of the CPAN Meta Specification should use JSON as the default implementation. As a consequence I then released Test-JSON-Meta.

Although the initial naming structure seemed the right the thing at the time, it is becoming clearer that really the names need to be revised. As such I looking to change two of the distributions to better fit the implementations. So in the coming weeks expect to see some updates. The name changes I'm planning are:

Underneath these current namespaces is the Version module that describes the data structures of the various specifications. In the short term these will also move, but will be replaced by a dependency on the main CPAN-Meta distribution in the future. There will be final releases for Test-YAML-Meta and Test-JSON-Meta, which will act as a wrapper distribution to re-point the respective distributions to their new identities.

Testing for validity is now very easy with CPAN::Meta. It's just this:

  CPAN::Meta->load_file($file, {lazy_validation => 0})

It will throw an exception if the file is not a valid CPAN Meta file.

It works with either YAML or JSON files and for any historical version of the specification.

So Test::CPAN::Meta should just be a simple Test wrapper around that.
