# SCHEMA algo — A2A Grocery

GSC's grocery knowledge graph: six datasets on one record.

- SKUs — The item: its Global Trade Item Number (GTIN; EAN in European copy), its label and claims, its pack, its place on the shelf, its lane.
- Chains — The retail banners: banner, parent group, channel, local format, market, cited points of sale, the buyer desk by department.
- HITL — The auditor and documents lane: certificates, specifications, allergen statements, origin declarations — the paper behind a product, read by a person where a person is needed.
- Economics — Price, availability, terms, promotion windows, order intents and settlement.
- Makers — Makers, brand owners, private-label owners, distributors, importers and brokers — each resolved to a verified identity.
- Acts — The rules: market status by product type, labelling and claims, organic and novel-food requirements, enforcement watch — twenty markets on fourteen rule sets.

Four temperatures: ambient, chilled, frozen, fresh. Six lanes: organic, free-from, plant-based, artisan, origin, premium. Eight departments. Five channels.
