GDS is the team responsible for the much anticipated GOV.UK website, which will act as a single domain for citizens to access services and information across government.

The team has been using Drupal as its CMS for many months, but decided to bring in Sirius to help it harness additional features, as well as get advice on its use of other open source technologies.

Sirius' CEO, Mark Taylor told Computerworld UK about the work he has been doing with GDS.

"GDS started working on Drupal themselves, but got a bit stuck and needed some help. Drupal is awesome, but it has a steep learning curve. It also has a bunch of modules, such as e-commerce and spam blocking, which GDS wanted to take advantage of," said Taylor.

"We have done some workshops with them on this, some strategic work, training courses, basically shown them the capability of Drupal and best practice."
