Done a great job of working out the order of things in the consumer Jacob! This looks grand. The only things missing for a 100% addition of a new source is the following:

• Update main so that the new source is an option
• "Basic" parameter set option in the client
• Integration test on the new source using the basic parameter set
• Passing unit test suite

Also just to check - it seems like this source doesn't need any auth, is that right?
But you've nailed the pattern, I hope it wasn't too painful to get your head around!
