Catmandu::Validator::MARC - Validate MARC records against a MARC21 Schema

SYNOPSIS

In Perl code:

            

              
              
use Catmandu::Validator::MARC;
Catmandu::Validator::MARC;
use DDP;
     
# load default MARC schema
my $validator = Catmandu::Validator::MARC->new();
# ... or load custom MARC schema
my $validator = Catmandu::Validator::MARC->new( schema => 'schema.json' );
my $importer = Catmandu::Importer::MARC->new(
    file => 't/camel.mrc',
    type => "ISO"
);
$importer->each( sub {
    my $record = shift;
    unless($validator->validate($record)){
        p $_ for @{$validator->last_errors()};
    }
});
            
          

In Catmandu Fix language:

            

              
              
# reject all items not conforming to the default MARC schema
select valid(., MARC)
# reject all items not conforming to a custom MARC schema
select valid(., MARC, schema: 'schema.json')
