https://wiki.eclipse.org/OM2M/REST_API
In "Create a description contentInstance" example：

body：
<obj>
<str name="type" val="Temperature_Sensor"/>
<str name="location" val="Home"/>
<str name="appId" val="MY_SENSOR"/>
<op name="getValue" href="gscl/applications/MY_SENSOR/containers/DATA/contentInstances/latest/content"
in="obix:Nil" out="obix:Nil" is="retrieve"/>
</obj>

What are both in and out mean?
thx

Hello,

In general, the "in" and "out" enables defining the operation contract. They can be used respectively to provide information to the user about the input and output of an operation.
For example, the "in" attribute can be used to define an obix representation to send as payload for POST request (is attribute is equal to "create" in this case)

Regards,
Mahdi
