BagIt (for ruby)

Based on the BagItspec v0.97.

Supported Features:

• bag compiling
• manifest & tagmanifest generation
• generation of tag files bag-info.txt and bagit.txt
• fetching remote files (fetch.txt)
• bag validation

Installation

% gem install bagit validatable

The rubyforge gem is deprecated.

Example: making a bag

require 'bagit'

# make a new bag at base_path
bag = BagIt::Bag.new base_path

# make a new file
bag.add_file("samplefile") do |io|
  io.puts "Hello Bag!"
end

# generate the manifest and tagmanifest files
bag.manifest!

Example: validating an existing bag

bag = BagIt::Bag.new existing_base_path

if bag.valid?
  puts "#{existing_base_path} is valid"
else
  puts "#{existing_base_path} is not valid"
end

Console Tool

# create a new bag/add files to existing bag
bagit add -f file1 file2 -t tagfile1 tagfile2 ./path/to/bag	
# validate
bagit validate ./path/to/bag
# for other commands
bagit --help

TODO

• deep directory add/delete for bag and tag files in console tools
• better holy bag (fetch.txt) generation
• better error reporting.
