Architecture of data.gov.uk

The data.gov.uk (DGU) platform is used to publish and view datasets. A dataset contains the metadata for a collection of links to data hosted somewhere on the internet.

data.gov.uk Services

Services owned by data.gov.uk

  • CKAN is the publishing app for datasets (‘packages’).
  • Find is the public frontend for searching datasets using Opencsearch.
  • Publish is a prototype publishing app for datasets. Whilst not public facing, it currently syncs data from CKAN into Opensearch for use in Find.
  • Reference is a legacy service that attempts to provide a nomenclature of time intervals, hosted on Heroku.

Services with data.gov.uk sub-domains, but owned by other departments

Several datasets link to environment.data.gov.uk and require user login to access. Although branded as data.gov.uk, this is a totally separate service. If a user is having difficulty accessing this system, they should contact the maintainers of this resource, who are currently Airbus Defence & Space.

CKAN, Publish and Find

CKAN, Publish and Find are hosted on AWS EKS and is maintained/deployed in the same way as most other GOV.UK applications.
