Hi all,

A while ago, there was some discussion about Memento (Time Travel for  
the Web) on the list. A lot has happened since then, and here is a  

(*) A few 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/.

(*) A demonstrator was built that shows how Memento concepts can be  
applied to Linked Data. It consists of:
- An archive at Los Alamos of the previous versions of the DBpedia  
dataset that exposes a Memento TimeGate (datetime negotiable resource)  
for each subject resource.
- An HTTP Link header pointing from each (current) DBpedia subject URI  
to the appropriate TimeGate. Many thanks to Chris Bizer, Kingsley  
Idehen, and Mitko Iliev for making this happen!

This set-up allows "follow your nose" HTTP navigation across versions  
of DBepdia descriptions. A suggested demonstration is described at http://www.mementoweb.org/demo/ 
. Our LDoW 2010 paper (available at http://arxiv.org/abs/1003.3661)  
describes the concepts and the demonstrator.

(*) There is now a Memento plug-in available for FireFox. It allows  
setting a date to browse the Web with. The plug-in and a suggested  
demonstration is available via http://www.mementoweb.org/demo/.

(*) There is a Memento plug-in available for the MediaWiki platform.  
See http://www.mediawiki.org/wiki/Extension:Memento . If you run one,  
please install it an let us know the URI for the Wiki.

(*) Some major Web Archives have started working towards Memento  
support. See http://www.mementoweb.org/events/IA201002/.

We are very interested in your feedback. Note that there is a Memento  
list at http://groups.google.com/group/memento-dev/.
