Newsletter 7 December 2020

In this newsletter attention for the following:

  • KDP progress
  • Tyk migration
  • Phasing out old version Meteo data
  • INSPIRE compatible (compliant) data products will soon be provided with harmonized metadata

KDP progress

The KDP development team has started to build radar APIs and improve/rationalize the radar production chain. The latter is aimed at the controlled, faster deployment of improvements in radar products (from research to operational product). Together with the radar user group, we decided to set up a 'data notification API' as a first improvement. This allows a user to register to receive a message as soon as new data within a dataset is available.

In the coming weeks the team will focus on testing this API with the radar user group.

In order to be in line with the API government guidelines we have adapted the current APIs. The old versions will remain available in parallel. See the page about our API deprication policy.

Tyk migration

On December 17th, 2020, we will execute a Tyk migration. Tyk is the API management platform used by KNMI. During the migration, the following functionalities will be temporarily unavailable in the Developer Portal:

  • User registration;
  • User authentication;
  • Requests for new API keys;

Existing API keys will continue to work during and after the migration. There should be no down-time for the available APIs. Users don’t have to make changes to their existing applications.

Phasing out old version Meteo data

For your information; The original version of the dataset 'Meteo data - current synoptic weather observations KNMI Nederland per 10 minutes' (Actuele10mindataKNMIstations/1) will be phased out (planned for the end of the first quarter of 2021) and will permanently be replaced by the new version Actuele10mindataKNMIstations/2. The new version has been available for some time and contains both the date and the measurement time in the file name.

INSPIRE compatible (compliant) data products will soon be provided with harmonized metadata

INSPIRE (INfrastructure for SPatial InfoRmation in Europe) is a European framework directive for an EU infrastructure that enables the exchange of geo-information for (re)use by governments and the general public. KNMI is currently working on making 5 harmonized KDP datasets available in accordance with these guidelines:

  • Earthquakes Netherlands,
  • Controlled daily climate data,
  • Current synoptic weather observations,
  • Network of KNMI observation stations,
  • Seismological measuring stations.

The metadata then meets the INSPIRE requirements and is harmonized and has uniform EU characteristics and definitions of objects and (mandatory) attributes. This allows it to be easily exchanged via services and compared with each other.
