SEE ALSO

Use Catmandu::PICA for processing PICA records with the Catmandu toolkit, for instance to convert PICA XML to plain PICA+:

catmandu convert PICA --type xml to PICA --type plain < picadata.xml

PICA::Record implements an alternative framework for processing PICA+ records but development of the module is stalled.
