bagit

bagit is a Python library and command line utility for working with BagIt style packages.

Installation

bagit.py is a single-file python module that you can drop into your project as needed or you can install globally with:

pip install bagit

Usage

From python you can use the bagit module to make a bag like this:

import bagit
bag = bagit.make_bag('mydir', {'Contact-Name': 'Ed Summers'})

Or if you've got an existing bag

import bagit
bag = bagit.Bag('/path/to/bag')

Or from the command line:

bagit.py --contact-name 'Ed Summers' mydir

If you want to validate a bag you can:

bag = bagit.Bag('/path/to/bag')
if bag.validate():
    print "yay :)"
else:
    print "boo :("

If you'd like to generate the checksums using parallel system processes, instead of single process:

bagit.make_bag('mydir', {'Contact-Name': 'Ed Summers'}, processes=4) 

or:

bagit.py --processes 4 --contact-name 'Ed Summers' mydir

bag --help will give the full set of options.

Development

% git clone git://github.com/edsu/bagit.git
% cd bagit 
% python test.py

If you'd like to see how increasing parallelization of bag creation on your system effects the time to create a bag try using the included bench utility:

% ./bench.py
