  The spec declares no components.schemas — every response schema is inline and
  anonymous. Entities below are derived from the inline response object shapes and
  their id-bearing fields (logger_sn, sensor_sn); names are assigned by this
  pipeline for the graph and are not provider-published type names.
entities:
- name: Logger
  description: A HOBO data logger, identified by serial number.
  identifier: logger_sn
  fields:
  - {name: logger_sn, type: string, role: identifier}
  source: openapi/li-cor-intermediate-hobolink-openapi.json#/paths/~1v1~1data/get/responses/200
- name: Sensor
  description: A sensor attached to a logger, identified by serial number.
  identifier: sensor_sn
  fields:
  - {name: sensor_sn, type: string, role: identifier}
  - {name: measurement_type, type: string}
  - {name: sensor_measurement_type, type: string}
  - {name: unit, type: string}
  - {name: meta_data, type: string}
  source: openapi/li-cor-intermediate-hobolink-openapi.json
- name: Observation
  description: A single timestamped sensor reading.
  identifier: null
  fields:
  - {name: timestamp, type: string, format: 'yyyy-MM-dd HH:mm:ss UTC'}
  - {name: value, type: number}
  - {name: unit, type: string}
  - {name: data_type, type: string}
  - {name: data_type_id, type: string}
  - {name: logger_sn, type: string, role: reference}
  - {name: sensor_sn, type: string, role: reference}

relationships:
- from: Logger
  to: Sensor
  kind: has_many
  via: logger_sn
  evidence: observations in /v1/data carry both logger_sn and sensor_sn
- from: Sensor
  to: Observation
  kind: has_many
  via: sensor_sn
  evidence: /v1/newa/{device-serial-number} nests observations[] inside each sensors[] item
- from: Observation
  to: Sensor
  kind: belongs_to
  via: sensor_sn
- from: Observation
  to: Logger
  kind: belongs_to
  via: logger_sn
response_shapes:
- operation: GET /v1/data
  shape: flat
  envelope:
    message: string
    max_results: boolean
    data: array of Observation
- operation: GET /v1/newa/{device-serial-number}
  shape: nested
  envelope:
    more_data: boolean
    sensors: array of Sensor, each with a nested observations array
