Hi Felix,

FYI, we started discussing setting functionality, but as we came up with a number of complicated issues we restricted the discussion to getting functionality for the first draft of the API.

In my understanding the API specification defines the functions for accessing all our properties, i.e. the input/output parameters and the expected behaviour. This does not include the specification of how to parse/write a certain format. All we specify should be format independent. 

Some of formats we have considered will be supported by the reference implementations. Anyone can develop own implementations of the API with open or closed libraries for accessing a certain format.
