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. -Kate 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: http://www.digitalpreservation.gov/documents/bagitspec.pdf == 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: https://github.com/LibraryOfCongress/bagit-java/ https://github.com/LibraryOfCongress/bagit-python http://sourceforge.net/projects/loc-xferutils/files/loc-bagger/ ############################ To unsubscribe from the NDSA-STANDARDS list: write to: mailto:[log in to unmask] or click the following link: http://list.digitalpreservation.gov/scripts/wa-DIGITAL.exe?SUBED1=NDSA-STANDARDS&A=1
