What is Semantic Modeling Language?
Semantic Modeling Language (SML) is an open-source, YAML-based standard for defining semantic models that work across BI and AI tools.
Why it matters:
- Define metrics and dimensions once, reuse them everywhere
- Human-readable, code-friendly, and version-controlled in Git
- Supports complex analytics (hierarchies, relationships, custom measures) Open and extensible for any business logic
