Connotea To Del.icio.us

I wanted to import all my Connotea bookmarks into my Del.icio.us account for a small experiment I was running. So I glued together the two APIs with a simple Ruby script.

The script uses the Ridiculous wrapper for the Del.icio.us API and my own www-connotea-ruby for the Connotea Web API.

I had problems installing Ridiculous from Rubygems, so I pulled it down from the SVN repository

    $ svn co svn://rubyforge.org//var/svn/ridiculous/0.5

I had to patch ridiculous.rb with this.

I downloaded www-connotea-ruby and extracted it

    $ tar xvzf www-connotea-ruby-0.1.tar.gz

And the connecting glue was just a few lines:

#!/usr/bin/env ruby

# contodel.rb
# by Ben Lund, Jan 2007

# Usage: ruby contodel.rb connotea_username:connotea_password delicious_username:delicious_password

require '0.5/ridiculous'
require 'www-connotea-ruby-0.1/lib/www/connotea'

c_user, c_pass = *ARGV.shift.split(/:/)
Ridiculous::USERNAME, Ridiculous::PASSWORD = *ARGV.shift.split(/:/)

c = WWW::Connotea.new(:user => c_user, :password => c_pass)

c.posts_for(:user=> c_user) do |p|
  success = false
  begin
    success = Ridiculous::Post.new.add(
      :url => p.link,
      :description => p.title || p.link,
      :extended => p.description,
        # Convert multi-word tags to underscore-separated
        # And convert all to lowercase to overcome case-insensitivity 
  
      :tags => p.tags.map{|t| t.gsub(/\s+/, '_').downcase }.join(' ') )
  end
  raise "Couldn't post #{p.link}" unless success

  #give the del.icio.us server a rest
  sleep(1)
end

Update: Via Stew, a script to go back the other way from Konstantin Baierer.
