Senior Java Developer

KOOP is seeking a Senior Java Developer to work on data.Overheid.Nl, the platform that makes government data discoverable and reusable. The data.Overheid.Nl team is responsible for the platform's continued development. The core of the project involves replacing the current CKAN metadata store and implementing the DCAT-AP-NL 3.0 profile for metadata exchange. Suppliers can provide metadata for data.Overheid.Nl in various ways: manually through the user interface or via an automated integration. The project aims to prepare data.Overheid.Nl for the future with the following activities:

• Replacing the CKAN metadata store;
  
• Implement DCAT-AP-NL 3.0 so that suppliers can use this new standard;
  
• Optimizing backend processes and collaboration with the frontend that is being redesigned.

Assignment Background: Since 2011, data.Overheid.Nl has been the national metadata registry used to make datasets from government organizations discoverable. The platform supports organizations in opening up their data and promotes reuse by providing search functionality. The registry uses national and European standards for metadata exchange and also offers the option to submit data requests to make data available as open data. Further development of data.Overheid.Nl is necessary to align with new developments and further improve services. Examples include supporting DCAT-AP-NL 3.0 and complying with obligations under the Implementing Regulation for High Value Datasets and the Data Governance Regulation.

Responsibilities

• You will work on the further development of data.Overheid.Nl, thus contributing to a future-proof national metadata register for Dutch government data.
• You will help replace the current metadata store and lay the foundation for exchanging linked data.
• You implement the DCAT-AP-NL 3.0 profile, so that data suppliers can easily apply the new standard.
