Delicious-couch is a project mainly written in Ruby, it's free.
Back up saved bookmarks from Delicous to CouchDB using Ruby
A few Ruby scripts to backup Delicious bookmarks to CouchDB and provide some simple queries
nokogiri and couchrest gems must be installed
sudo gem install nokogiri couchrest
git clone https://github.com/stevenwilkin/delicious-couch
cd delicious-couch
Substitute your username and password on the command line
USER=username PASS=password ./import.rb
./views.rb
Now that the database had been populated and the views created, the contents can be queried
./list_urls.rb
./count_tags.rb
./urls_by_tag.rb git
Views all bookmarks tagged with "git"
This set of scripts is only scraping the surface of what is possible with CouchDB but it demonstrates the immense power of MapReduce along with the basics interacting with CouchDB using Ruby. Enjoy!
