Characteristic
object type
A characteristic — a master-list entry for VALIDATED product values (serial-number, warranty period, …): value type + validation grammar + optional unit; distinct from Tags (unstructured labels), Categories (navigation), and Options (variant-driving). Canned + custom: system-shipped IMMUTABLE templates are copied via copyCannedCharacteristic; group-defined customs are created directly — references (the Manufacturer format map; the spine) always point at group-owned constructs, never templates. TWO_STATE — no inactive (a master-list entry is usable or gone).
Fields
| Field | Type | Notes |
|---|---|---|
id | ID ID! | The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it. |
sysId | String String! | The group-scoped human-facing system id (CH-…). |
type | String String! | The kind of record — always Characteristic here. |
caption | String String! | The record’s display name — what people see it called. |
status | String String! | The FSM state: active | doomed. |
parentId | ID ID! | The parent org group; for a Characteristic parentId === rootId. |
rootId | ID ID! | The org-group family root. |
createdAt | String String! | When the record was created, as a UTC timestamp. |
updatedAt | String String! | When the record last changed, as a UTC timestamp. |
revisionNum | Int Int! | How many times this record has been edited; the first save is 0. |
revision | ID ID! | The OCC revision token — supply it on every mutation of this record; rotates on every write. |
refCaptions | RefCaption [RefCaption!]! | The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption. |
valueType | CharacteristicValueType CharacteristicValueType! | The value type (canned registry) — set at creation, IMMUTABLE thereafter. |
grammar | CharacteristicGrammar | Optional validation grammar; REQUIRED (with pattern) on a pattern-typed characteristic; refused on number/date (STRICT). |
unit | String | Optional canned-UoM unit code; absent = dimensionless. |
code | String | Optional mutable merchant reference code; uniqueness NOT enforced (the code stance). |
