PBIR format

[New_worker]

Hi-

Here's a definition.pbir file: 

{
"version": "1.0",
"datasetReference": {
"byPath": {
"path": "../Sales.Dataset"
},
"byConnection": null
}
}

I want to confirm the meaning of version=1.0, does it refer to PBIR-Legacy format or jsut a restrict value for version?

Although I walk through the related document, I cannot understand PBIR-Legacy format should be determined by report.json or version=1.0 in .pbir file..

Version Supported formats

1.0	Report definition must be stored as PBIR-Legacy in the report.json file.
4.0 or higher	Report definition can be stored as PBIR-Legacy (report.json file) or PBIR (\definition folder).

Thanks!

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).

The version=1.0 in the definition.pbir file indicates that the report definition is stored in the PBIR-Legacy format, which means the report metadata is saved in the report.json file. This is consistent with the documentation, where version 1.0 explicitly requires the use of the PBIR-Legacy format.

1.0	Report definition must be stored as PBIR-Legacy in the report.json file.
4.0 or higher	Report definition can be stored as PBIR-Legacy (report.json file) or PBIR (\definition folder).

Thank you @ribisht17  for the reply.

So, I can understand version=1.0 refers to the report definition must be stored in report.json, which is in PBIR Legacy format. But the statement "definition.pbir is in the PBIR-Legacy format" is wrong, it is still PBIP format, right?
Correct me if I misunderstand. Thanks!

PBIP has two methods of storing the semantic model and report.

The semantic model can be stored as legacy in TMSL (model.bim) or TMDL.

The report as legacy in report.json or PBIR
