Term	Kind	Topic	What it is
Airbnb Minerva: One Definition of a Metric Minerva Metrics Platform	case-study	Semantic Layer	Airbnb built a central metrics platform because the same business question was producing different answers depending on which dashboard you opened.
Metric Definition Layer	pattern	Semantic Layer	Business metrics defined once in a versioned, tested place and served to every consuming tool, so the number cannot differ by which tool asked.
Point-in-Time Correctness As-Of Join, Temporal Correctness, Leakage Prevention	concept	Semantic Layer	Retrieving each feature's value as it was at the moment of the event rather than its current value, which is what prevents a model from training on information that did not exist yet.
Semantic Layer Metrics Layer, Headless BI	pattern	Semantic Layer	A single governed definition of business metrics and entities, sitting between physical tables and every consuming tool.
