NAME

Catmandu::Importer::MARC - Package that imports MARC data

SYNOPSIS

use Catmandu;

# import records from file
my $importer = Catmandu->importer('MARC',file => '/foo/bar.mrc');

my $count = $importer->each(sub {
    my $record = shift;
    # ...
});

# import records and apply a fixer
my $fixer = fixer("marc_map('245a','title')");

$fixer->fix($importer)->each(sub {
    my $record = shift;
    printf "title: %s\n" , $record->{title};
});

# Convert MARC to JSON mapping 245a to a title with the L<catmandu> command line client:

catmandu convert MARC --fix "marc_map('245a','title')" < /foo/bar.mrc
