=head1 NAME

PICA::Parser::JSON - PICA JSON parser

=head2 DESCRIPTION

This parser parses L<PICA JSON|http://format.gbv.de/pica/json> format. The
current implementation expects records to be on a line each (newline delimited
JSON), this may be extended to full JSON in a later version.

Records may also be given as object with field C<record>.

See L<PICA::Parser::Base> for synopsis and basic configuration.

The counterpart of this module is L<PICA::Writer::JSON>.
