Karl Hammar, Assistant Professor of Computer Science at Jönköping University in Sweden, introduces the RealEstateCore ontology – an open-source data model for smart buildings, based on established practices in the real estate, construction, and building management sectors, but supporting leading-edge IoT-based scenarios. Karl is joined by Alina Stanciu from the Azure Smart Places & Energy and Azure Digital Twins to describe the RealEstateCore types and relations, how these models can be uploaded and used in Azure Digital Twins and exemplify how queries built against these models can be reused across multiple deployments to prove the benefits of model standardization and data interoperability.
