There is a need to collect, store, and share product data to enable circularity in industrialized construction supply chains. To do this, the concept of a Material Passport (MP) has been proposed, but exactly how MPs should be created and managed is less understood, especially in consideration of industrialized construction product platforms. This paper proposes a knowledge and process representation framework called the Material Passport Ontology (MPO). The MPO outlines key components of MPs and their interrelationships. Finally, the paper discusses several implementation challenges and possibilities.

In the upcoming era of distributed technological integration known as Web3, the built environment will need to adapt. Solving the most significant social, environmental and economic challenges will likely require new approaches to data sharing and efficient data management. This will need to occur within organizations, across software tools, and between partners. However, today’s approach of data fragmentation and a scattered system of data islands prevent efficient data usage in the construction industry.The question that now arises is whether the decentralized marketplace approach has the potential to make construction data sets more uniform, efficient,and usable for all stakeholders through distributed technological integration.Therefore, this paper’s contribution isto provide a conceptual starting point and possible research stream approach towards thisquestion. Doing so by outlining current data management challenges and discussing themin comparison with already existing web3 approaches in research and industry.
