Probably all of the implemented NEPs should have their own place in
the documentation and other parts should reference the NEPs for

It's not as formalized as the .npy format, but I expect it to be at
least as solid as other code in numpy.

It is independent of numpy version numbering. If we do upgrade the
format, the code in numpy.io will still be able to read and write 1.0
> 4. This page http://www.scipy.org/Data_sets_and_examples talks about including data sets with scipy, has this happened? Would it be possible to include a single small dataset in numpy for use in examples?
I think the dataset convention is entirely independent of numpy per
se. The current version of this stuff is in the scikits.learn package:
The proposal could be turned into an "informative" NEP, of course. It
needs to be updated, though (e.g. it talks about not needing to
combine masked arrays and record arrays, but this has already been
done with the numpy.ma rewrite).

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
