We were engaged by the History of Parliament Trust to work on their flagship website that publishes the results of research into the members and constituencies of all British parliaments since 1386.

This data rich web site is managed by the Drupal CMS and has tens of thousands of 'nodes'.
We were tasked with solving various issues with the site's performance and importing data from the DTP files used to create the published volumes. A real challenge that required an in depth understanding of Drupal and how to get the best performance from the database and the web site code. The data import was made possible by our in-house XML translation tools.
We re-factored much of the existing code and rebuilt the site using the existing 'theme' design. The sitewent live in July 2011 and the site now performs excellently and uses a variety of caching and other performance techniques.
