We are excited to share some news about the Memento (Time Travel for the
Web) effort. Memento proposes to extend HTTP with datetime content
negotiation as a means to better integrate the present and past Web. The
Memento effort is partly funded by the Library of Congress.

=> The MementoFox add-on for FireFox browsers has been released. It allows
time travel on the Web in a manner compliant with the Memento framework.
  *  The MementoFox add-on can be downloaded at <
https://addons.mozilla.org/en-US/firefox/addon/100298>.
  *  Suggested Web time travels that can be undertaken using the add-on are
described at <http://www.mementoweb.org/demo/>. They involve navigations for
both the document Web and the Linked Data cloud.

=> There is also a Memento plug-in available for the MediaWiki
platform.  The plug-in provides support for Memento-style navigation of a
Wiki's history pages.
  *  The MediaWiki plug-in can be downloaded at  <
http://www.mediawiki.org/wiki/Extension:Memento>.
  *  If you run a MediaWiki platform, please install this plug-in and let us
know the URI of your Wiki.

=> Further pointers for recent Memento developments:
  *  Memento site <http://www.mementoweb.org>.
  *  Since Memento was first announced in November 2009, improvements have
been made to the technical framework. Most notably, all of the concerns
related to Web caching have been addressed such that the framwork now takes
maximal advantage of the existing caching infrastructure. Overviews of the
framework are available via <http://www.mementoweb.org/guide/>.
  *  Some major Web Archives have started working towards Memento support.
See <http://www.mementoweb.org/events/IA201002/>.

We are very interested in your feedback. Discussions are welcomed on the
Memento list at <http://groups.google.com/group/memento-dev/>.
