This document defines a binding for the JSON Meta Application Protocol (JMAP) over a WebSocket transport layer. A WebSocket binding for JMAP provides higher performance than the current HTTP binding for JMAP. Open Issues o Should we allow push notifications over the WS connection? o Should we allow out of order processing od requests?
