Action and / or Property Behavior

Hi all,

I have a kind of naive question, just to know if I fully understand the way Redfish "works":

For example :
Chassis has a "Status" property.
According to specification, this property is NOT readonly.

Does it mean that it is possible to send a PUT on the RF server to make it change ?
Or should I have a corresponding real OEM Action like "ChangeStatus",  to change that Property (in that case, what is the purpose of "PUT" behavior) ?

I mean every property that is not readonly could be changed immediatly by a simple 'PUT' sent on the Redfish server that will have the behavior (action?) to change the status ?

In other words, some properties reflect a "State" without the possibility to be set and some other properties are both exposing a state and a way to change that value , is it right ?

Does it means that 'Actions' are reserved to Properties without "values" or "states", but more simple function without results, like Reset that could not be on/off ?

I know my question is certainly obvious, well, I should develop the client part with label / form / ... html components to reflect a good Redfish behavior,

Regards,
Francine
