i'd define it as "measureable" goals. How does your mentor, who isn't only 
mentor but also assessor, know that you reached your goals or not. If we don't 
define deliverables properly, there would be much more room for interpretation.

I'm perfectly fine if you say "I will work on problem X and provide a solution 
at May, 31th. Then there are 7 days for discussions. Starting with June, 8th, I 
will start with the implementation.".

you don't have to and you can't because you will learn and find out things that 
you don't know today. Also the opinion of your mentor and the feedback from the 
community will influence your project.

  If so, I would like to make use of this right when

ok, forget my comment 4 and 5 and leave it open for now. Only add a paragraph to 
the timeline about when you will let us know what converters and samples you 
want to implement.

This and adding a timeline and a deliverables section should be all that needs 
to be done IMO.

no, just take it into account when you propose a timeline.
