Beside actors, there are a few more properties listed to be expressed by contributors: Actors_Display, Advisories and Director. In the actual RDF file, only Actors and Directors are present. Advisories and Actors_display make no real sense in this example, but an automatic conversion would generate Contributors with the according values. How should we behave here? From my point of view, we have to define a behavior here (adding all, adding only exact if present, etc.). In the locator property of the RDF, "US" is the value, but actually not specified in the Example.

> <App_Data App="MOD" Name="Chapter" Value="00:15:12:00,They Meet"/>
> <App_Data App="MOD" Name="Chapter" Value="02:03:06:00,The Collision"/>
> <App_Data App="MOD" Name="Chapter" Value="02:55:15:00,She Goes Under"/>
> <App_Data App="MOD" Name="Chapter" Value="03:02:09:00,Final Scene"/>
