UK Government Web Archive
Archive Content
The UK Government Web Archive is made available by the UK National Archives and consists of
archived versions of UK government information published on the web.
Further information about this web archive is available via its home page.
Memento Protocol Information
The UK Government 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
Presuming the Original Resource (current version) is
http://www.direct.gov.uk/en/Nl1/Newsroom/index.htm,
then the resources that are relevant for the Memento protocol are:
- TimeGate:
http://mementoproxy.lanl.gov/uk/timegate/http://www.direct.gov.uk/en/Nl1/Newsroom/index.htm - Memento:
http://webarchive.nationalarchives.gov.uk/20101125161449/http://www.direct.gov.uk/en/Nl1/Newsroom/index.htm; etc. - TimeMap:
http://mementoproxy.lanl.gov/uk/timemap/link/http://www.direct.gov.uk/en/Nl1/Newsroom/index.htm - TimeBundle:
http://mementoproxy.lanl.gov/uk/timebundle/http://www.direct.gov.uk/en/Nl1/Newsroom/index.htm
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.
Integration with the Original Dataset
The original dataset is UK Government web sites. In responses to HTTP requests,
these resources don't provide a
Link header with a "
timegate" link to point at
their TimeGate for the UK Government Web Archive.
