However, the current recommendations for material passports focus on material information at a building scale with little attention to its implications on a city scale. This paper provides directions for developing a material passport ontology that could be used to collect, store, share, and retrieve data at multiple scales of abstraction. It describes the requirements for a MP ontology and provides recommendations for integrating existing ontologies. This paper is relevant to researchers developing information management platforms to enable a circular economy Keywords: Material passport, circular economy, cities, ontology, semantic webPaper:EC32022_212
