I am doing research on concurrent editing of shared objects and I am
thinking on using Wikipedia as a source for update patterns. After
downloading and importing the database to my mysql, I can now check
the info I need: Object, User and Timestamp.
However, I noticed that unlike other Wikis there is no longer a lock when
multiple users concurrently try to edit the same object. As you know, currently
in Wikipedia the user that tries to commit a concurrent version will get asked
to merge its contents with the previously commited state.
My questions is:
Is there any flag on table "old" that indicates that a given update was done
after merging with the previous version ? This kind of information
would be usefull for my extraction of patterns, since I am interested on the
conflict rate.
Thanks in advance for any help that you might be able to give me.
Regards,
Carlos
