   * https://github.com/playlouder/persistence[A set of interfaces for, and implementations of, the Repository pattern in Ruby.] This one looks promising.

    include Entrepot::Model

  This is a learning experiment, pull requests are welcome! Bonus points for feature branches.
  
  To get started, see https://github.com/paulrayner/ddd_sample_app_ruby/issues?state=open[milestones and issues]. Use the https://github.com/SzymonPobiega/DDDSample.Net[vanilla .NET port version] as the basis for any work.
  
  Progress and learning will be shared after the DDD Exchange on June 14 through posts on http://thepaulrayner.com[Paul Rayner's blog].
