NAME

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

SYNOPSIS

    # From the command line
    $ catmandu convert MARC --fix "marc_map('245a','title')" < /foo/bar.mrc

    # From Perl
    use Catmandu;

    # import records from file
    my $importer = Catmandu->importer('MARC',file => '/foo/bar.mrc');
    my $fixer    = Catmandu->fixer("marc_map('245a','title')");

    $importer->each(sub {
        my $item = shift;
        ...
    });

    # or using the fixer

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

DESCRIPTION

Catmandu::Importer::MARC is a Catmandu::Iterable to import MARC records from an external source. When given an input file an Catmandu::Iterable is create generating items as perl HASH-es containing two keys:

     '_id'    : the system identifier of the record (usually the 001 field) 
     'record' : an ARRAY of ARRAYs containing the record data

  'record' => [
