Decentralised Data Exchange in Construction Data Spaces Using Information Containers

Abstract: The construction industry is decentralised by nature and, thus, suited for leveraging the Data Space concept. The ICDD specification offers a solution for targeted data sharing through dedicated connectors to create secure and interoperable decentralised data ecosystems. This study uses the International Data Spaces Reference Architecture Model to develop a Data Space that integrates ICDD containers as queryable web resources within the IDS framework. The approach is validated in a circular construction case allowing exchange of multimodal data via the Data Space. As a data consumer, a marketplace application retrieves building elements available for reuse from decentralised containers.
