Lessons Learned in the Pursuit of Production-Readiness: Iterative Evaluation of the Kadaster Knowledge Graph Construction

The application of linked data has played a role in enhancing the accessibility and reusability of data at the Kadaster, the Dutch National Land Administration and Mapping Agency. Over the past decade, three distinct iterations of linked data creation, publication, and integration have emerged. The most recent iteration involves the KKG, now published using a nationally standardised model and an enterprise-ready architecture, transitioning it into a production-ready data product. This paper evaluates each iteration, identifies key requirements for production-readiness in a governmental context, and presents lessons learned to guide other organisations in adopting linked data technologies. A design science methodology is used to perform the evaluations and the findings reveal the importance of strategic alignment, specialised expertise, and ongoing evaluation in achieving and sustainability of production-readiness in linked data architectures. This research provides valuable insights into the practical adoption of linked data over a decade-long period, offering a unique longitudinal perspective. The lessons from Kadaster’s experience can serve as a roadmap for other institutions aiming to integrate linked data into their operations. Future research could expand on these findings to explore the scalability of the approach in different organisational contexts and its impact on data accessibility and utility.
