NAME

Catmandu::Exporter::BagIt - Package that exports data as BagIts

SYNOPSIS

   use Catmandu::Exporter::BagIt;

   my $exporter = Catmandu::Exporter::BagIt->new(
                            overwrite     => 0 ,
                            skip_manifest => 0,
                  );

   $exporter->add($bagit_record);

   $exporter->commit;

BagIt

The parsed BagIt record is a HASH containing the key '_id' containing the BagIt directory name and one or more fields:

    {
          '_id' => 'bags/demo01',
          'version' => '0.97',                          # Not required, all bags will be 0.97
          'tags' => {
                      'Bagging-Date' => '2014-10-03',   # Not required, generated ...
                      'Bag-Software-Agent' => 'FooBar', # Not required, generated ...
                      'DC-Title'   => 'My downloads' ,
                      'DC-Creator' => 'Bunny, Bugs' ,
                    },
           },
           'fetch' => [
               { 'http://server/download1.pdf'  => 'data/my_download1.pdf' } ,
               { 'http://server2/download2.pdf' => 'data/my_download2.pdf' } ,
           ],
    };

All URL's in the fetch array will be mirrored and added to the bag. All payload files should be put in the 'data' subdirectory as shown in the example above.

METHODS

This module inherits all methods of Catmandu::Exporter.

CONFIGURATION

In addition to the configuration provided by Catmandu::Exporter the exporter can be configured with the following parameters:

ignore_existing

Optional. Skip an item when the BagIt for it already exists.

overwrite

Optional. Throws an Catmandu::Error when the exporter tries to overwrite an existing directory.

skip_manifest

Optional. Skips the re-calculation of MD5 manifest checksums in case BagIt directories get overwritten. Use this option for instance when overwriting only the tags of a bag.
