Hi,
Thanks for following up on this, Kate. I've also found the State Archives of North Carolina's video tutorial series on Bagit very useful as we're looking at ways to embed better stewardship practices into our workflows:

Subject: [NDSA-STANDARDS] BagIt
Hi, all,
A question came up about BagIt, and I thought I'd share some information. If anyone wants to chat further, I'm happy to.

When people say BagIt, it's not always clear what they mean. It's generally one of two things:
1. The BagIt specification
2. Software written to help people make bags
== The BagIt specification ==
The BagIt specification describes a file packaging format ("bags") for storage and transfer of content and metadata.
A bag is a file system directory that contains at least the following:
* a "data" directory that includes the data files that comprise the digital content being preserved
* at least one manifest file that itemizes the filenames present in the "data" directory, as well as their checksums
* a "bagit.txt" file that identifies the directory as a bag, the version of the BagIt specification that it adheres to, and the character encoding used for tag files
This video gives a good overview: http://www.youtube.com/watch?v=l3p3ao_JSfo
The wikipedia article: http://en.wikipedia.org/wiki/BagIt
The spec itself:

== Software for making bags ==
There are a bunch of tools available for making and working with bags. Some we maintain here at LC, some are made by other folks. I'll link to a few of the LC projects below:
