Archive-It Web Archive

This document provides information about the Archive-It Web Archive that is Memento compatible via a proxy solution.

Questions and comments are welcome on memento-dev@googlegroups.com.

The Archive-It Web Archive is operated by the Internet Archive and consists of collection-oriented web archives. Archive-It is a subscription web archiving service that helps organizations to harvest, build, and preserve collections of digital content. Further information about this web archive is available via its home page.

The Archive-It Web Archive is accessible via the Memento "Time Travel for the Web" protocol through a by proxy solution. Because of the proxy nature of the Memento support, responses are typically slower than they would be with native Memento support. Nevertheless, the proxy solution provides support for datetime negotiation to access a version of a web resource as it existed at a specific moment in time. Check out the brief introduction to Memento if you are not familiar with it.

Presuming the Original Resource (current version) is http://lib.ugent.be/, then the resources that are relevant for the Memento protocol are:

• TimeGate: http://mementoproxy.lanl.gov/ait/timegate/http://lib.ugent.be/
• Memento: http://wayback.archive-it.org/505/20120415105138/http://lib.ugent.be/ ; etc.
• TimeMap: http://mementoproxy.lanl.gov/ait/timemap/link/http://lib.ugent.be/
• TimeBundle: http://mementoproxy.lanl.gov/ait/timebundle/http://lib.ugent.be/

In response to HTTP requests, Web resources for which archived versions exist in the Archive-It Web Archive typically don't provide a Link header with a "timegate" link to point at their TimeGate for Archive-It. However, when specific servers are recurrently being archived by Archive-It, as is, for example, the case with http://lib.ugent.be/, they could add such links to response headers, for example, by using an appropriate Apache rewrite rule.
