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

         '_id' => 'fol05882032'
        }

METHODS

   new(file => $filename, type => $type)
       Create a new MARC importer for $filename. Use STDIN when no filename is given.  Type
       describes the MARC parser to be used. Currently we support:

       USMARC    Catmandu::Importer::MARC::USMARC
       MicroLIF  Catmandu::Importer::MARC::MicroLIF
       MARCMaker Catmandu::Importer::MARC::MARCMaker
       JSON      Catmandu::Importer::MARC::MiJ
       XML       Catmandu::Importer::MARC::XML
       RAW       Catmandu::Importer::MARC::RAW
       Lint      Catmandu::Importer::MARC::Lint
       ALEPHSEQ  Catmandu::Importer::MARC::ALEPHSEQ

       Read the documentation of the parser modules for extra configuration options.

   count
   each(&callback)
   ...
       Every Catmandu::Importer is a Catmandu::Iterable all its methods are inherited.
