Query: Bringing Web Time Travel to MediaWiki: An Assessment of the Memento
  MediaWiki Extension   We have implemented the Memento MediaWiki Extension Version 2.0, which brings
the Memento Protocol to MediaWiki, used by Wikipedia and the Wikimedia
Foundation. Test results show that the extension has a negligible impact on
performance. Two 302 status code datetime negotiation patterns, as defined by
Memento, have been examined for the extension: Pattern 1.1, which requires 2
requests, versus Pattern 2.1, which requires 3 requests. Our test results and
mathematical review find that, contrary to intuition, Pattern 2.1 performs
better than Pattern 1.1 due to idiosyncrasies in MediaWiki. In addition to
implementing Memento, Version 2.0 allows administrators to choose the optional
200-style datetime negotiation Pattern 1.2 instead of Pattern 2.1. It also
permits administrators the ability to have the Memento MediaWiki Extension
return full HTTP 400 and 500 status codes rather than using standard MediaWiki
error pages. Finally, version 2.0 permits administrators to turn off
recommended Memento headers if desired. Seeing as much of our work focuses on
producing the correct revision of a wiki page in response to a user's datetime
input, we also examine the problem of finding the correct revisions of the
embedded resources, including images, stylesheets, and JavaScript; identifying
the issues and discussing whether or not MediaWiki must be changed to support
this functionality.
