Thanks a lot, Its really helpful to understand.
Swagger version openapi: 3.0.1 is too much lengthy, its taking too much time to load objects on GUI. Even sometime its not displaying actual object fields.

Hi Chetan,
TMF760 is a version 5 Open API and uses Swagger / Open API 3.0 meaning the schemas may use inheritance (allof keyword).
Characteristic class is abstract and extended with subclasses of a specific type, e.g. string characteristic, number characteristic, etc. See diagram below:
Also, have a look at the Swagger definition:
Characteristic:
allOf:
- $ref: '#/components/schemas/Extensible'
- type: object
description: Describes a given characteristic of an object or entity through a name/value pair.
properties:
id:
type: string
description: Unique identifier of the characteristic
name:
type: string
description: Name of the characteristic
valueType:
type: string
description: Data type of the value of the characteristic
characteristicRelationship:
type: array
items:
$ref: '#/components/schemas/CharacteristicRelationship'
discriminator:
propertyName: '@type'
mapping:
Characteristic: '#/components/schemas/Characteristic'
StringCharacteristic: '#/components/schemas/StringCharacteristic'
StringArrayCharacteristic: '#/components/schemas/StringArrayCharacteristic'
ObjectCharacteristic: '#/components/schemas/ObjectCharacteristic'
ObjectArrayCharacteristic: '#/components/schemas/ObjectArrayCharacteristic'
NumberCharacteristic: '#/components/schemas/NumberCharacteristic'
NumberArrayCharacteristic: '#/components/schemas/NumberArrayCharacteristic'
IntegerCharacteristic: '#/components/schemas/IntegerCharacteristic'
IntegerArrayCharacteristic: '#/components/schemas/IntegerArrayCharacteristic'
FloatCharacteristic: '#/components/schemas/FloatCharacteristic'
FloatArrayCharacteristic: '#/components/schemas/FloatArrayCharacteristic'
@type attribute is used as a discriminator to determine the characteristic type.
The actual value is stored in the value attribute of each subclass, e.g. StringCharacteristic.value.
StringCharacteristic:
allOf:
- $ref: '#/components/schemas/Characteristic'
- type: object
description: A characteristic which value is a String.
properties:
value:
type: string
description: Value of the characteristic
Hope it helps.

Hi Team,
@Bostjan Keber @Jonathan Goldberg
We are getting characteristic object without "value" field so does it correct or mistake in swagger? Why each object have @type is mandatory?
