 ## Road to GraphQL
 
-Going forward, we will start on moving to
-[GraphQL](http://graphql.org/learn/best-practices/) and deprecate the use of

-
-1. We avoid having to maintain two different APIs.
-2. Callers of the API can request only what they need.
-3. It is versioned by default.
-
-It will co-exist with the current v4 REST API. If we have a v5 API, this should
