Graph as a service platform A graph-as-a-service platform, App.Co allows you to persist graph data simply, via a RESTful JSON API. It provides powerful tools to operate on your private custom graph. App.Co clients can run complex graph queries (which would be hard, or impossible using a regular DB), which can mix in third party APIs (such as Facebook, Twitter) Think Facebook Open Graph (which we are compatible with - we make it easier to use), but extended, and without having all of your valuable edge data inside FB.
