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 summary: (*) 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/.
