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 _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
