Sending an entity type with children to an OData service (MVC Web Api)

Question

I searched for the answers to the following questions, but haven’t found them yet.

• Does the OData standard support the execution of a POST request containing an entity object with child entity objects?
• If so, does ASP.NET MVC Web Api OData framework ( EntitySetController) support this out of the box?

The scenario that I mean looks something like this: You have an object Parentthat contains several objects Child. Could you do a POST with such a body?

{ "Property1" : "Property value", "Property2" : 100 
     "Children" : [
          { "ChildProperty" : "Some value" },
          { "ChildProperty" : "Some other value" },
          { "ChildProperty" : "Some third value" }
     ]
}

Also, if later I would like to add another child to the object Parentthrough POSTing of one child, is there a standardized way to combine them? Sort of

 { "ChildProperty" : "Fourth child property val", "Parent" : 321 }

where '321' is the parent id?
