You have a Microsoft Power BI project that contains a file named definition.

PBIR-Legacy format → No

Located in Power BI service → No

Opens in full edit mode → Yes

Comprehensive Detailed Explanation

We are analyzing a Power BI Report (PBIR) definition file in JSON format:

{

"version": "1.0",

"byPath": {

"path": "../Sales.Dataset"

}

}

}

Step 1: Is this PBIR-Legacy?

PBIR-Legacy format is used when referencing a dataset hosted in the Power BI service (cloud).

In this case, the JSON uses byPath, which references a local dataset file (Sales.Dataset) in the project folder, not a service dataset.

Therefore: No, it is not PBIR-Legacy.

Step 2: Where is the semantic model located?

The datasetReference points to ../Sales.Dataset.

That means the semantic model is stored locally in the project structure, not in the Power BI service.

Therefore: No, it is not located in the Power BI service.

Step 3: What happens when opening in Power BI Desktop?

Since the dataset reference is local (byPath), Power BI Desktop opens the semantic model in full edit mode (allowing schema, relationships, measures, etc. to be modified).

If it were PBIR-Legacy with a service model, only Live Connection mode would be available.

Therefore: Yes, Power BI Desktop opens it in full edit mode.
