CSV import

CSV is the primary path for offline engineering — import vendor exports without live BACnet/Modbus.

Formats

Consult the ingest contract for required columns:

curl -s http://127.0.0.1:8080/api/ingest/contract | jq .

Supported shapes include historian-wide CSV and commissioning JSON (separate endpoint).

Validation

Preflight checks timestamp columns, units, equipment/site IDs, and duplicate keys. Strict mode (OPENFDD_CSV_STRICT, default on) rejects execute on fail verdict.

API

Method	Path
GET	/api/ingest/contract
