Here are a few ideas of scenarios: a) a store with a catalog of goods, and a shopping cart app, similar to the Tuscany store sample; b) an app allowing you to track the location of your friends, you build a list of friends, they update their location, and you can query for the 5 closest ones; c) a Twitter-like app, you follow a list of people and see the messages they write. These three scenarios have pretty different write / read / query characteristics. We already have REST service examples for (a) in our store sample. You could just build on that, but if you want more fun, I think it'd be really interesting to try to come with REST services for (b) or (c) as well. Any thoughts from others in the team? -- Jean-Sebastien
