Actually, the revision table allows for non-linear development (it stores from which version you edited the article). You could even make to "win" a version different than the one with the latest timestamp (by changing page_rev) one. You will need to change the way of viewing history, however, and add a system to keep track of "heads" and "merges". There may be some assumtions accross the codebase about the latest revision being the active one, too. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
