What we're building

We need to describe the overall goal we're trying to achieve with DM2, break it up into manageable small steps and come up with a realistic timeframe / amount of hours to make it happen.

How to reach out

• Look through lanyrd and ask people we know if they can spread the word about our campaign at conferences
• Contact popular podcasts and ask if they're willing to feature our campaign and ask people to contribute
  • rubyrogues
• changelog

## Problem

Currently, relationships are stored in a hash. This means that the order in which they were created gets lost.

* A model with a composite primary key that is made up of two foreign keys (e.g. a join table)
* Only the relationships are defined (using #belongs_to)
* Properties are *not* explicitly defined (using #property)
