UK Web Archive

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

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

The UK Web Archive is operated by the British Library and consists of thousands of UK web sites collected since 2004. Further information about this web archive is available via its home page.

The UK Web Archive 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://www.tate.org.uk/, then the resources that are relevant for the Memento protocol are:

• TimeGate: http://mementoproxy.lanl.gov/bl/timegate/http://www.tate.org.uk/
• Memento: http://www.webarchive.org.uk/wayback/archive/20090828170135/http://www.tate.org.uk/ ; etc.
• TimeMap: http://mementoproxy.lanl.gov/bl/timemap/link/http://www.tate.org.uk
• TimeBundle: http://mementoproxy.lanl.gov/bl/timebundle/http://www.tate.org.uk

Further information:

• The TimeBundle is a more expressive, RDF-based, version of the TimeMap. One major distinction is that the TimeBundle expresses the interval of temporal validity of a Memento, i.e. the time period in which the Memento was the current version of the Original Resource.

The original dataset is the UK web. In responses to HTTP requests, Web resources typically don't provide a Link header with a "timegate" link to point at their TimeGate for the UK Web Archive.
