Lot Formation and Transformation

1. 01 Harvest creates source lots

   A harvest event identifies the producing field or management zones, time, quantity, crop, and other relevant production context. One harvest may create several lots because of grade, storage, harvest window, or handling.

2. 02 Packing can divide or combine

   A pack operation may divide one source lot into several commercial lots or combine several source lots into one pack lot. Both operations must preserve lineage.

3. 03 Processing creates transformation relationships

   When raw agricultural products are washed, cut, blended, milled, cooked, or otherwise transformed, the new product acquires a new identity while retaining links to contributing source lots.

4. 04 Shipments aggregate commercial movement

   A shipment can contain multiple lots from multiple farms. The shipment is a transport object, not a substitute for provenance.

5. 05 Receipt extends the chain

   Buyer receipt, warehouse movement, further transformation, resale, and other downstream events can continue the lineage using compatible traceability structures such as GS1 EPCIS where appropriate.

The Production Passport

The Landscape Passport

• hydrology

  The passport can state which hydrologic systems contain the production field and, where the data support it, how the field relates to downstream waters.

  Relates to watershed, catchment, downstream-waterbody, drainage-context

• groundwater

  The passport can describe relevant groundwater context independently from surface watershed membership.

  Relates to aquifer, basin, well, irrigation

• soils

  Mapped soil units and actual field measurements remain separately represented so a buyer can understand both context and evidence.

  Relates to mapped-context, sample-observations, management-zone

• terrain

  Terrain helps explain why the same management practice can have different implications on different fields.

  Relates to slope, elevation, flow-path, erosion-context

• habitat

  Ecological surroundings provide landscape context without implying that proximity alone proves an environmental outcome.

  Relates to riparian-area, wetland, corridor, neighboring-land-cover

• climate

  Climate and observed weather help interpret production risk and outcome variability.

  Relates to production-cycle, weather, drought, water-demand

One Provenance, Different Authorized Views

1. Consumers receive a story, not the farm database

   A consumer view may explain farm, region, production approach, and selected evidence without exposing exact coordinates, yields, or sensitive operational records.

2. Buyers receive decision-relevant evidence

   A procurement team may inspect production requirements, practice history, certifications, landscape risks, evidence sufficiency, and lot lineage needed for sourcing decisions.

3. Auditors receive provenance

   An auditor can inspect the chain connecting claims to events and evidence without necessarily receiving commercial pricing or unrelated farm data.

4. Agronomists receive production context

   An authorized advisor can examine crop history, soil context, measurements, interventions, and field observations at the resolution needed for agronomic reasoning.

5. Researchers receive governed datasets

   Research access can be anonymized, aggregated, or permissioned depending upon the question and producer agreement.
