Microsoft partnered with domain experts to create DTDL model sets based on industry standards. These model sets help minimize reinvention and simplify solutions. This article presents the DTDL industry ontologies that are currently available.
List of ontologies

| Smart buildings | Digital Twins Definition Language-based RealEstateCore ontology for smart buildings | Microsoft partnered with RealEstateCore to deliver this open-source DTDL ontology for the real estate industry. RealEstateCore is a consortium of real estate owners, software vendors, and research institutions. This smart buildings ontology provides common ground for modeling smart buildings, using industry standards (like BRICK Schema or W3C Building Topology Ontology) to avoid reinvention. The ontology also comes with best practices for how to consume and properly extend it. |
To learn more about the partnership with RealEstateCore and goals for this initiative, see the following blog post and embedded video: RealEstateCore, a smart building ontology for digital twins, is now available. |
| Manufacturing | Manufacturing Ontologies | These ontologies help solution providers accelerate development of digital twin solutions for manufacturing use cases like asset condition monitoring, simulation, OEE calculation, and predictive maintenance. Additionally, the ontologies can be used to enable the digital transformation and modernization of factories and plants. They're adapted from OPC UA, ISA95, and the Asset Administration Shell, three global standards widely used in the manufacturing space. | Visit the repository to learn more about this ontology and explore a sample solution for ingesting OPC UA data into Azure Digital Twins. |
