Is there currently a way to navigate documentation through a network of notebooks interface?

This would seem to fall into an advanced application into the domain of nbconvert preprocessing (I think).

Where one is going from a file-hierarchy of documentation files in a way that acts as sphinx for the notebook rather than for the internet. Or is that the riddle?

Are there other examples of open-source interactive, code-example based documentation editing engines from which some system like this could derive lessons?

A great documentation editor would make it much more interesting for people to edit documentation. Because they can be writing code at the same time, editing documentation could be an excellent opportunity to sharpen your coding skills and be sure that you are up to date about relatively novel techniques, since you can receive further corrections by other contributors with different expertises by virtue of the documentation being open-source.

If there is no such engine, what user interface notions should I acquaint myself with if I wanted to build a way to just edit and navigate python documentation(e.g., that of nbconvert) in a convenient notebook interface?

@sbenthall are there any good user interface paradigms for social graph munging (in the data plumbing sense, not the destructive systems-data munging sense)?

Start by reviewing nbconvert preprocessing and the existing notebook documentation structure mentioned in the issue. Compare open-source interactive, code-example-based documentation editors and notebook navigation interfaces. Done would require a concrete proposal defining the interface, documentation workflow, and implementation scope.
