# DESCRIPTION

Catmandu::PICA provides methods to work with PICA data within the [Catmandu](https://metacpan.org/pod/Catmandu)
framework.  

See [PICA::Data](https://metacpan.org/pod/PICA%3A%3AData) for more information about PICA data format and record
structure.

See [Catmandu::Introduction](https://metacpan.org/pod/Catmandu%3A%3AIntroduction) and [http://librecat.org/Catmandu](http://librecat.org/Catmandu) for an
introduction into Catmandu.
