Not directly. There is a dependency graph between calclets and
datasets, which implies a partial order. But there is no strict linear
order as for cells in a notebook.

BTW, that's related to one of the open questions I have with
integrating notebooks into ActivePapers: how to handle the case of a
notebook whose cells have been executed interactively in a different
order? This may well result in different datasets than a complete
linear execution, so the cell execution order needs to be stored for
reproduction. Is this information available in a notebook?

Right, this could be the occasion to think about more general
approaches of using notebooks as interfaces for back-ends of various
kinds.
