- UK Government Web Archive
From 1997 to 2010, The National Archives selected government datasets for archiving in the National Digital Archive of Datasets (NDAD), part of the University of London Computer Centre. Selected datasets were physically transferred from government departments, along with supporting contextual information. NDAD converted the data from its original format to the simple open CSV format in order to make the data available via the NDAD website for download or purchase as a DVD.
For more detailed information on this discontinued system, see the NDAD website which has been captured into the UK Government Web Archive http://webarchive.nationalarchives.gov.uk/20101104101827/http://www.ndad.nationalarchives.gov.uk/.
You can search for the actual data from NDAD in Discovery - our catalogue.
UK Government Web Archive (Since 2010)
The NDAD system was discontinued in 2010. The way that government publishes datasets has evolved and, as they are now made available on government websites, it is possible to capture and preserve them in the UK Government Web Archive.
Initially, we captured the datasets hosted on departments' websites at the same time that we archived the departments' websites themselves, meaning they can be accessed in the context of the government website at the time of the capture.
In December 2013, largely in response to the transition of many departmental websites to GOV.UK, our aim became to comprehensively capture all datasets listed on data.gov.uk twice per year, at the same time as our crawls of the data.gov.uk website itself. This allows the captures of the data.gov.uk website to act as a central place to access archived government datasets.
As with all other web content, archiving datasets is subject to the limitations of web archiving technology.
