Asset meter reading
Asset meter reading is one of Demiton's published registers for Australian civil construction. Odometer and engine-hour readings, as recorded. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
