Starter contract

agriculture_batch

13 rules · plain YAML · starts in observation mode

OpenDQV Cloud starter template (v0.1) — your tenant inherits this baseline. First customer edit creates v1.0 in your audit trail; pin by yaml_hash for replay. Agriculture crop batch record validation for supply chain traceability and food safety pipelines. Enforces UK crop type taxonomy aligned with AHDB (Agriculture and Horticulture Development Board) classification, food safety certification scheme validation (Red Tractor, LEAF Marque, Organic, Rainforest Alliance, Fairtrade), ISO 3166-1 country of origin for single-origin traceability under UK Food Information Regulations 2014, and yield anomaly detection. Supports GlobalG.A.P. chain-of-custody traceability requirements and DEFRA cross-compliance audit records.

These are starting points you own. Every rule below ships in the trial, starts in observation mode, and is yours to read, edit, or delete from day one. Rules that reference a lookup list (lookup_file) validate against reference data you control in your tenant.
Rules as at 29 August 2026 — starting points you own, not a maintained regulatory feed. We correct errors in these samples; tracking regulatory change in your active contracts is yours.
