Exchange APIs
An API can move bytes and records between farm systems. Interoperability requires more: both sides must preserve the identity and meaning of fields, boundaries, machines, products, operations, units, timestamps, geometry, versions, status, provenance, permissions, and errors without silently translating one concept into another.

Visual explanationA diagram or operating scene makes the relationship visible.
Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
A successful response
can still lose meaning.
AgGateway ADAPT and the Open Geospatial Consortium GeoPackage standard provide examples of agricultural and geospatial exchange frameworks. They support discussion of data models and portable containers without proving that any two products implement compatible versions or preserve every agricultural meaning.
A responsible integration defines the exact producer and consumer, contract version, record identities, mappings, units, time and timezone, geometry and coordinate reference, code lists, provenance, permissions, retries, duplicates, error handling, update behavior, and deletion semantics.
02 / Handoff loop
Map the contract,
transfer, verify, reconcile.
01CONTRACT / 01Freeze both system boundariesProducer and consumer, versions, authentication and authorization, endpoints or files, schema, limits, lifecycle, support, and change policy
02MAP / 02Preserve agricultural meaningStable identities, entities and relationships, code lists, units, timestamps and timezone, geometry and CRS, status, provenance, and null versus unknown
03TRANSFER / 03Handle transport honestlyPagination, ordering, retries, idempotency, duplicates, partial failure, rate limits, attachments, checksums, acknowledgements, and logs
04VERIFY / 04Reconcile source and destinationCounts derived from real records, field-level comparison, geometry and units, missing and extra entities, conflicts, rejected data, human review, and rollback

ReconciliationEvidence about one exchangeUniversal compatibility or future stability
04 / Practice
Test the round trip
and the failure path.
Protect entity identity
Prevent farms, fields, operations, assets, products, people, and seasons from being merged solely because labels look alike.
Exercise partial failure
Test retries, duplicates, missing pages, rejected records, expired credentials, network interruption, stale data, changed schemas, and rollback.
Compare records after transfer
Use deterministic counts, hashes where appropriate, sampled fields, geometry, units, provenance, and human review rather than trusting a success status.
05 / Boundaries
An API endpoint
is not a compatibility promise.
Exact interoperability is product- and version-specific.Use current authoritative documentation and representative testing for the precise producer, consumer, functions, market, data, and versions.
Standards do not eliminate mappings.Profiles, optional elements, extensions, identifiers, code lists, units, geometry, business rules, and implementation choices can differ.
Exchange does not grant permission or ownership.Contracts, consent, roles, security, privacy, licensing, retention, and deletion require their own authority and evidence.
