About MMM Proto Schema

The MMM Proto Schema is a language-agnostic data standard for representing trained Marketing Mix Models (MMMs) and their analysis artifacts in a consistent, serializable format. It establishes a common language for MMM outputs, allowing results from different tools and methodologies to be uniformly represented, stored, shared, and compared. This standardized representation enhances interoperability and facilitates downstream applications like scenario planning, optimization, and reporting.
