Tabular Model Definition Language (TMDL) is a game-changer for efficient Power BI development using code. With the new TMDL view in Power BI Desktop, developers can quickly create and modify semantic model objects, surpassing the capabilities of the Power BI Desktop UI. This allows for the generation and modification of semantic objects that previously required third-party tools, enabling standardized reusable scripts that benefit individual developers and their teams.

This presentation will begin with an introduction to TMDL, highlighting its unique features and differences from other scripting languages. Attendees will learn the syntax and common pitfalls to avoid. We will explore how the TMDL view integrates with Power BI projects and provide guidance on when to use it.

Additionally, we will examine the support for TMDL in other tools such as Tabular Editor and Visual Studio Code. One of the key advantages of TMDL is its text-based nature, allowing developers to use their preferred editors to develop and apply changes. We will also touch on source control and how it can be utilized to detect changes between models efficiently.

Finally, we will discuss common use cases and demonstrate how to leverage TMDL to become more effective and sought-after Power BI developers.
