Martijn van Tilburg commented on OLINGO-737:
--------------------------------------------

As also explained in 
https://stackoverflow.com/questions/35917293/odata-with-dynamic-attributes-for-complex-type
 , dynamic properties are currently not supported In OLingo V4. We briefly 
looked at which code should be changed to support it:
* Json and Atom serializer/deserializer must be customized
* ExpressionParser must be customized

We are considering to provide a patch to implement dynamic property handling, 
what we would like to know before attempting this:
* Is dynamic property support planned for OLingo V4? If so, is there a rough 
estimation on when it will be implemented?
* Is there anyone who tried to add support for it? If so, where can the code 
changes and/or documentation be found?
* Do you have any idea on how much effort it would take to implement dynamic 
property handling?

>  dynamic properties are not serialized.
> Specifically the JsonSerializer writeProperties method gets the list of 
> properties from the EntityType not from the Entity itself. Thus if the Entity 
> has additional dynamically added org.apache.olingo.commons.api.data.Property 
> objects they are missed.
