A Crash Course on YAML

This post will tell you how we use a simple YAML file to insert the initial data (like roles, privileges, admin user, and all the other necessary data) into our database. We use Play! Framework (Java) with Hibernate. The important part is how we make Objects from the YAML description using SnakeYAML (Play framework’s integrated YAML parser) though.
