Premiered: December 9th, 9am-10am PST with live Q&A and on-demand following the event. Deep Dives are interactive technical live and on-demand events for developers, architects, or anyone building IoT solutions. Microsoft engineers and guest speakers do technical deep dives about a new feature or scenario.

Integrating Digital Twins Definition language (DTDL) has completely transformed Willow's software development process and freed them from constrained hierarchical models while saving hours of development time. In this session we will take you through the end to end experience of WillowTwin's building solution to prove out the benefits of Azure Digital Twins, DTDL, and the broader Azure IoT ecosystem. The deep dive focuses on Azure Digital Twins capabilities in the solution context: Architecture from edge to data transformationFlexible modeling of the building with DTDL using interfaces, relationships, model inheritance, semantic units and reusable components.Automating the extraction of data, meta-data and system level relationships from Building Information Model (BIM) and creation of digital twins graph with instances and relationships using Azure Digital Twins C# SDKConnecting a digital twin to an advanced 3D model of the building using interactive experienceConnecting live data from the Building Management System to IoT Edge, IoT Hub, Azure Functions and Azure Digital Twins, all the way to front-end visualization in time-machine, historian trend logs that generates a
