Technology as a catalyst: technical architecture of the Cadastre-Registry ecosystem

Abstract

From the perspective of a technologist involved in its develop­ment, this article offers a technical and strategic analysis of the technological architecture that has underpinned the success of the Cadastre-Land Registry coordination in Spain. It argues that the model's triumph lies not solely in the legislation, but in the conceptual and engineering decisions that made it viable. The analysis delves into the four key technological pillars: the intelligent electronic document (PDF with embedded GML/XML), which eliminated transcription errors; standardization through the cadastral parcel GML-INSPIRE format, which ensured mathe­matical certainty over visual trust; the Secure Verification Code (CSV), as a seal of integrity and an enabler for automation; and the web services that orchestrated a real-time interoperability ecosystem. The text concludes by positioning this model as a pioneering case of a sectoral data space, anticipating the current European Data Strategy and laying the groundwork for the future intelligent management of the territory.
