About this service

The use of a query language gives an extremely powerful and flexible tool to explore the data available from the Open Data Hub without having to download large amounts of data.

Data can be combined and filtered on the server, so all the heavy duty work is kept off your computer and only the truly wanted data is transferred.

Being a W3C standard, support for SPARQL is provided by almost any tool and programming language used for working with data.

The services shown on this page are not a replacement of Open Data Hub, as operated by NOI.

The purpose is to show flexible alternatives to conventional WebAPIs.

The service is for demoing purposes only and comes without any guarantee on availability and data completeness.
