PBIR format

Thankyou, ribisht17, Deku, for your response.

Hi New_worker,

We sincerely appreciate your inquiry posted on the Microsoft Fabric Community Forum.

To the best of my understanding, within the Power BI Project (PBIP) format, the file named definition.pbir is itself a PBIP file and is not considered as PBIR-Legacy. The attribute version=1.0 inside definition.pbir dictates how the report content is stored. When the version is 1.0, the report definition must be saved separately in a file named report.json, following the PBIR-Legacy storage format for the report content. For versions 4.0 or above, you may use either report.json (PBIR-Legacy) or the newer \definition folder (PBIR format). Hence, definition.pbir is always in PBIP format, and the version 1.0 simply indicates that the report’s definition must conform to the PBIR-Legacy standard (i.e., using report.json).
