CreateAssetModel - AWS IoT SiteWise

CreateAssetModel

Creates an asset model from specified property and hierarchy definitions. You create assets from asset models. With asset models, you can easily create assets of the same type that have standardized definitions. Each asset created from a model inherits the asset model's property and hierarchy definitions. For more information, see Defining asset models in the AWS IoT SiteWise User Guide.

Required: No

clientToken

A unique case-sensitive identifier that you can provide to ensure the idempotency of the request. Don't reuse this client token if a new idempotent request is required.

Type: String

Length Constraints: Minimum length of 36. Maximum length of 64.

Pattern: \S{36,64}

Required: No

Pattern: .*

assetModelId

The ID of the asset model. You can use this ID when you call other AWS IoT SiteWise APIs.

Type: String

Length Constraints: Fixed length of 36.

Pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$

assetModelStatus

The status of the asset model, which contains a state (CREATING after successfully calling this operation) and any error message.

Type: AssetModelStatus object
