  2. How many of us watch?

  3. Getting Info On Our Favorite Fiction All of these are wikis! All of these wikis run MediaWiki!

  4. The Problem We haven’t caught up because of a job/ailing mother/bar crawl/life.

  5. The Problem We haven’t caught up because of a job/ailing mother/bar crawl/life. Wait, he’s dead? How do we avoid these spoilers?

  6. Current “Solution” Post a big SPOILER ALERT on the page I haven’t caught up. Is this Wiki even useful to me until I catch up? I’m afraid to use this site now. Site owners may be losing ad revenue because visitors turn away.

  7. The solution RFC 7089 describes the Memento Protocol Memento Chrome Extension by Los Alamos National Laboratory (LANL) User installs in browser Memento MediaWiki Extension by Old Dominion University and LANL Site administrator installs in MediaWiki

  8. Simplified Memento Overview

  9. DEMO • Let’s avoid some spoilers with A Song Of Ice and Fire… http://ws-dl-05.cs.odu.edu/demo/index.php/Kevan_Lannister https://www.youtube.com/watch?v=tb0g5D5LTiU

  10. DEMO Screenshots We want to find information about KevanLannister, but haven’t read the book A Dance with Dragons yet. We set the Memento Chrome Extension prior to the release of that book: June 29, 2011.

  11. DEMO Screenshots We use the Memento Chrome Extension to request a revision of the page close to, but not over, our requested date.

  12. DEMO Screenshots And we get the revision of the page closest, but not over, the date requested.

  13. DEMO Screenshots And, as you can see, this revision of the page has no information about A Dance With Dragons.

  14. DEMO Screenshots And that’s not all… I can browse the rest of the site, spoiler-free.

  15. DEMO Screenshots Here’s the past revision of the page about TommenBaratheon, as linked to, from the KevanLannister page, and still close to, but not over, our requested date.

  16.

  20. Memento Extension vs. Manually Getting Page Revision This is very time consuming. Memento let’s you browse through the whole web with a given date! Why do it when Memento will do it for you?

  21. Memento Extension vs. MediaWiki API JSON: {"revid":607345961,"parentid":607210719,"timestamp":"2014-05-06T16:07:52Z”} XML: <rev revid="607519915" parentid="607345961" user="Marklemagne" timestamp="2014-05-07T19:00:26Z"/> Only a custom MediaWiki client can turn these oldid entries into URIs. Memento is a web standard way of accessing old web resources and is already implemented for many different applications (web archives, etc.)

  22. Memento Extension vs. MediaWiki API Link: <http://ws-dl-05.cs.odu.edu/demo-302-recommended-relations/index.php/Daenerys_Targaryen>; rel="original latest-version", <http://ws-dl-05.cs.odu.edu/demo-302-recommended-relations/index.php/Special:TimeGate/Daenerys_Targaryen>; rel="timegate", <http://ws-dl-05.cs.odu.edu/demo-302-recommended-relations/index.php/Special:TimeMap/Daenerys_Targaryen>; rel="timemap"; type="application/link-format"; from="Sun, 22 Apr 2007 15:01:20 GMT"; until="Fri, 27 Sep 2013 20:48:24 GMT", <http://ws-dl-05.cs.odu.edu/demo-302-recommended-relations/index.php?title=Daenerys_Targaryen&oldid=1499>; rel="first memento"; datetime="Sun, 22 Apr 2007 15:01:20 GMT", <http://ws-dl-05.cs.odu.edu/demo-302-recommended-relations/index.php?title=Daenerys_Targaryen&oldid=107643>; rel="last memento"; datetime="Fri, 27 Sep 2013 20:48:24 GMT" Memento also follows the RESTful principle of “follow your nose”, indicating additional resources to access from here.

  23. Memento Extension vs. Internet Archive The Internet Archive only gets some of the revisions of a given page. MediaWiki has allof the revisions of a given page.

  24. Memento Extension vs. Other MediaWiki Time Travel Extensions While these extensions just work for MediaWiki, Memento works for the entire web. With the Memento extensions, one can browse the entire web spoiler free by seamlessly accessing web archives and other resources through Memento.
