+# Title
+
+Currently, openwhisk supports return json object only, e.g.
+```shell
+# wsk action invoke hello -r
+{
+    "greeting": "Hello stranger!"
+}
+```
+It is necessary to support return array, e.g.
+```shell
+# wsk action invoke hello-array -r
+[
+    "a",
+    "b"
+]
+```
+
+## Status
+* Current state: In-progress
+* Author(s): @ningyougang
+
+## Summary and Motivation
+
+This POEM proposes a new feature that allows user to write their own action which supports array result.
+So the result will support object and array both in future.
+
+## Proposed changes
+### Openwhisk repo
+Make controller and invoker support array result both.
+### Runtime repo
+Includes java, php, python, etc. All runtime images should supoprt array result.
+### Openwhisk-cli repo
+When use wsk execute action, need to support parse array result.
+When use wsk get activation, need to support parse array result as well.
