[Numpy-discussion] data transit

[Alan Isaac]

It sounds like you want a new class X that does three things:
knows where the data is and how to access  it,
knows how the data are to be processed and can do this when asked,
is able to provide a "results" object when requested.
The results object can store who made it and with what 
processing module, thus indirectly linking to the data and techniques
(which the X instance may or may not store, as is convenient).

fwiw,
Alan Isaac
