IoT Show: RealEstateCore, a smart building ontology for digital twins

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.

How is the model constructed? By hand, generated from BIM, etc?

[@alinastanciu4372]

The models are generated from RealEstateCore original ontology as we want to keep them compatible, they are not generated from BIM.

Are all these tools are free to use?

[@olivierbloch1256]

Lots of the tools and libraries used are open source and free to use however some of the services backing the solution up are paying (like Azure Digital Twins). Check out the repo mentioned in the description for details
