Thanks for starting this. Are you thinking that these are akin to user
stories for just the data, or for everything?

Besides the discussion you opened, there are related topics that can be
added, such as (but not totally):

 - What is the public API of the project, and how is it advertised?
 - What is the backwards-compatability policy should a change be needed to
the public API?

For those types of topics, there is inspiration from many of the
well-managed F/OSS ecosystems.

And this be a nit, but I think "What is the time now?" needs to be more
explicitly "What is the wall-time for a particular person now?" and similar
for past and future.
