   REST CRUD methods have record and collection "style" JSON-result sets but invokable methods are using ProDataSet style result sets, e.g. serialized ProDataSet structures. Is this intentionally or is it due to a Progress limitation or something else?

   You can return any JSON you like using the 
   
   response="return"
   
   option. When you make use of returning a ProDataset from the method, it feels more natural to return the ProDataset with it's built in serialization options.

   Ok, thanks! I now understand and can implement what we want. Still have to decided what we want.

   We have our own method, something like GetInitialValues in SCL, that in my mind seems more natural if it would return a record in the same way like when using REST Read?

   Nothing holds you back to return whatever you want. Define the method with RETURN JsonObject or JsonArray and the annotation with response=return.

   Yeah, I understood that. :)
   Just wanted to get an opinion about GetInitialValues style of invokable method and what result set would be most natural in a RESTful world.

   GetInitialValues does not represent a resource at rest per se (it's not a record in the database). 
   
   It's a request to return a template for a new record. I doubt that any third party application would ever make use of that API. So return whatever is handy for your client.
