One source, multiple queries: making KIK-V data available for regional data collaboration

August 2025

This article references work originally published in Dutch on Datawerkplaats.net. For your convenience, we have summarised it here.

Together with NLcom and Zorginstituut Nederland (the Dutch National Health Care Institute), we ran a first practical trial showing how a care provider can take part — through a single integration — in both a national data query (KIK-V) and a regional data analysis via a data collaboration like GERDA. Data that is already prepared in a KIK-V datastation — the DaaS environment provided by NLcom (or by another DaaS provider) — can be made available to a Linksight datastation, to take part in regional queries. The technology underpinning GERDA is Linksight’s.

For care providers this would mean a noticeable simplification: the same data does not need to be unlocked twice, and the data steward keeps track from a single environment (the Linksight Governance Hub) of which queries are running, who is allowed to use which data, and for what purpose.

“Both forms of querying were carried out successfully. This demonstrates that it is possible to make data available for multiple forms of secondary data use.”
