support for Memento-based access to archived versions of URLs

[Robert Jäschke]

The Memento protocol allows clients to access old (archived) versions of a URL. Therefore, the client sends a request to a TimeGate containing the URL and a date. The TimeGate then sends a redirect to the archived version of the URL, if one exists.

Implementing this functionality for bookmarks would enable users to access a version of the web page that is most close in time to the bookmarking date. It would also help to access pages which have been deleted.

There already exist some tools which can help to implement the Memento protocol. Further steps should be discussed with @jaeschke.

It seems that we can use the memento service of the British web archive, e.g.,

http://www.webarchive.org.uk/mementos/search/http%3A//www.bibsonomy.org/

We would need to find out, though, how to request a specific date.

The curl client shows nicely how it works and having a look on the code. What we need is a TimeGate server, there are some shown on the web page but we need to find out which one we can/should use.
