NAME

Archive::BagIt - An interface to make and verify bags according to the BagIt standard

VERSION

version 0.070

WARNING

This is experimental software for the moment and under active development.

Under the hood, the module Archive::BagIt::Base was adapted and extended to support BagIt 1.0 according to RFC 8493 ([https://tools.ietf.org/html/rfc8493](https://tools.ietf.org/html/rfc8493)).

Also: Check out Archive::BagIt::Fast if you are willing to add some extra dependencies to get better speed by mmap-ing files.

SUBROUTINES

new

An Object Oriented Interface to a bag. Opens an existing bag.

my $bag = Archive::BagIt->new('/path/to/bag');

make_bag

A constructor that will make and return a bag from a directory

If a data directory exists, assume it is already a bag (no checking for invalid files in root)

verify_bag

An interface to verify a bag.

You might also want to check Archive::BagIt::Fast to see a more direct way of accessing files (and thus faster).

get_checksum

This is the checksum for the bag, md5 of the manifest-md5.txt

version

Returns the bagit version according to the bagit.txt file.

payload_files

Returns an array with all of the payload files (those files that are below the data directory)

non_payload_files

Returns an array with files that are in the root of the bag, non-manifest files

manifest_files

Return an array with the list of manifest files that exist in the bag

tagmanifest_files

Return an array with the list of tagmanifest files

SYNOPSIS

This modules will hopefully help with the basic commands needed to create and verify a bag. My intention is not to be strict and enforce all of the specification. The reference implementation is the java version and I will endeavour to maintain compatibility with it.

use Archive::BagIt;

#read in an existing bag:
my $bag_dir = "/path/to/bag";
my $bag = Archive::BagIt->new($bag_dir);


#construct bag in an existing directory
my $bag2 = Archive::BagIt->make_bag($bag_dir);

# Validate a BagIt archive against its manifest
my $bag3 = Archive::BagIt->new($bag_dir);
my $is_valid = $bag3->verify_bag();
