+
+* Pojo Façade - persist POJOs as JSON objects and use a simple API to query them with all the power

+* Eval (and Invoke) - directly access MarkLogic's powerful server-side XQuery or JavaScript

+* JavaScript Extensions - develop production-ready server-side extensions using ready-to-go scaffolding
