A URI is an identifier of something (eg a local authority, a service, an area).
Used by computer programs, URIs provide machine readable data and allow those programs to link to associated data.
What does this tool provide?
This page lets you look up URIs from popular URI sets that are used to link data across UK local government.
If your council uses different text labels for specific URIs, sign in and use the Map to URI page to link your labels to corresponding URIs.
The API documentation page describes programmatic ways of looking up URIs from official and locally defined text labels.
