Model Spec

A Model Spec is a structured plan for a semantic model. Review it before building, keep it in source control and use it again when the model changes.

What it contains

The spec records storage mode, source information, tables, columns, relationships, core measures and time-intelligence measures. You can start from an empty form, inspect an open model or read a Fabric SQL endpoint to create a first draft.

The Model Spec workspace showing tables, relationships and measures in a structured plan.

Build from the spec

  1. Review the proposed tables, keys and relationships.
  2. Correct source assumptions and add the measures the business needs.
  3. Preview the build.
  4. Apply it to an empty or open model as one reviewed change.
First draft

A generated spec is a starting point. Fabric sources often do not declare every key, so review relationships and business logic before building.
