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();
This is experimental software for the moment and under active development. I hope to have a beta version available soon.
We use it fairly widely in-house, but it doesn't necessarily implement all of the specs.
Email me with anything you need done urgently.
Also: Check out Archive::BagIt::Fast if you are willing to add some extra dependendies to get better speed by mmap-ing files.
Archive::BagIt - An interface to make and verify bags according to the BagIt standard
An Object Oriented Interface to a bag. Opens an existing 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)
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).
This is the checksum for the bag, md5 of the manifest-md5.txt
Returns the bagit version according to the bagit.txt file.
Returns an array with all of the payload files (those files that are below the data directory)
Returns an array with files that are in the root of the bag, non-manifest files
return an array with the list of manifest files that exist in the bag
return an array with the list of tagmanifest files
