Architecture of

The platform is used to publish and view datasets. A dataset is a document about a collection of links to documentation or data hosted somewhere on the Internet. The platform has the following software.

  • CKAN is the legacy publishing and finder app for datasets (‘packages’). It also runs Nginx to support Find.
  • Find is the public frontend for searching datasets using Elasticsearch. It replaces CKAN for certain routes.
  • Publish is the prototype publishing app for datasets. It currently syncs with CKAN to populate Elasitcsearch.

Publish and Find

Publish and Find are provisioned on GOV.UK Paas using Terraform. The deployment and monitoring pages explain this in more detail, but you can use the following commands to get an overview.

cf apps
cf services
cf routes
cf env publish-data-beta-production

We use GOV.UK Signon for user authentication in Publish Data, with the app in each environment linked to the corresponding instance of GOV.UK Signon. See the Publish ADR for more info.
