What file format should you use to save a semantic model using the Tabular Model Definition Language?

The file format used to save a semantic model with Tabular Model Definition Language (TMDL) is specifically designed to facilitate the creation and sharing of tabular models.

The PBIP format is particularly relevant here as it includes not only the semantic model's metadata but also the data connections and configurations that are essential for building and maintaining a tabular model in tools like Microsoft Power BI. This format supports the combination of the model structure with Power BI-specific features, making it easier for users to work with complex data models in a collaborative environment.

By contrast, the other file formats, such as PBIX and PBIT, serve different purposes related to Power BI projects but do not focus on the semantic aspects in the same context as PBIP. PBIX files are commonly used for reports and datasets, while PBIT serves as a template for new reports but does not capture the detailed model aspect provided by PBIP. PBIDS files are specifically for data source definitions and are not a model file format.
