This may be true in MediaWiki but not so much for external tools. I just wanted to preemptively say this. I'll be joining the IRC discussion to share more :)
Excellent, thank you! It would be particularly interesting to know what assumptions you make about the semantics of rev_parent_id. E.g. there are
three
revisions, A, B, and C, and revision B gets romoved - what should
revision C's
parent be?
Similarly, when revision X gets imported and inserted between A and B,
what
should revision B's parent be?

I think in such a case, revision C's parent should benull or 0. Similarly for revision X.
I dont view the parent as what revision came first but what revision was edited to make this revision (i.e. where the current revision was "forked" off from) -- Brian
