Open Gastronomy Standard
A machine-readable vocabulary for ingredients, dishes, beverages, and pairings — plus the official benchmark for evaluating gastronomy-capable AI. OGS is JSON-first, schema-validated, and ontology-compatible so recipes, menus, tasting notes, and pairing engines can be exchanged and reasoned about by both humans and machines.
What OGS covers
- ingredient — sensory profile, category, provenance
- dish — components, roles, cooking methods, resulting sensory profile
- beverage — structural attributes, aromatics, typology
- pairing — scored, explainable match between a dish and a beverage
- cuisine — culinary tradition with endonym-first naming and optional hierarchy
Identifiers use ogs:<namespace>:<type>:<id>.
Conformance levels L1 (structural), L2 (vocabulary), and L3 (semantic) support incremental adoption.
OGS-Bench
Twelve capability categories — from controlled vocabulary and sensory prediction to safety, nutrition, and menu engineering — scored with deterministic metrics on a 0–100 scale.
