CreateAssetModelCompositeModel

Creates a custom composite model from specified property and hierarchy definitions. There are two types of custom composite models, inline and component-model-based.

Use component-model-based custom composite models to define standard, reusable components. A component-model-based custom composite model consists of a name, a description, and the ID of the component model it references. A component-model-based custom composite model has no properties of its own; its referenced component model provides its associated properties to any created assets. For more information, see Custom composite models (Components) in the AWS IoT SiteWise User Guide.

Use inline custom composite models to organize the properties of an asset model. The properties of inline custom composite models are local to the asset model where they are included and can't be used to create multiple assets.

To create a component-model-based model, specify the composedAssetModelId of an existing asset model with assetModelType of COMPONENT_MODEL.

To create an inline model, specify the assetModelCompositeModelProperties and don't include an composedAssetModelId.

URI Request Parameters

The request uses the following URI parameters.

assetModelId

The ID of the asset model this composite model is a part of.

Length Constraints: Minimum length of 13. Maximum length of 139.

Pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$|^externalId:[a-zA-Z0-9][a-zA-Z_\-0-9.:]*[a-zA-Z0-9]+

Required: Yes

ifMatch

The expected current entity tag (ETag) for the asset model’s latest or active version (specified using matchForVersionType). The create request is rejected if the tag does not match the latest or active version's current entity tag. See Optimistic locking for asset model writes in the AWS IoT SiteWise User Guide.

Pattern: ^[\w-]{43}$

ifNoneMatch

Accepts * to reject the create request if an active version (specified using matchForVersionType as ACTIVE) already exists for the asset model.

Pattern: \*

matchForVersionType

Specifies the asset model version type (LATEST or ACTIVE) used in conjunction with If-Match or If-None-Match headers to determine the target ETag for the create operation.

Valid Values: LATEST | ACTIVE

Request Body

The request accepts the following data in JSON format.

assetModelCompositeModelDescription

A description for the composite model.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

assetModelCompositeModelExternalId

An external ID to assign to the composite model.

If the composite model is a derived composite model, or one nested inside a component model, you can only set the external ID using UpdateAssetModelCompositeModel and specifying the derived ID of the model or property from the created model it's a part of.

Type: String

assetModelCompositeModelId

The ID of the composite model. AWS IoT SiteWise automatically generates a unique ID for you, so this parameter is never required. However, if you prefer to supply your own ID instead, you can specify it here in UUID format. If you specify your own ID, it must be globally unique.

Required: Yes

assetModelCompositeModelProperties

The property definitions of the composite model. For more information, see Inline custom composite models in the AWS IoT SiteWise User Guide.

You can specify up to 200 properties per composite model. For more information, see Quotas in the AWS IoT SiteWise User Guide.

Type: Array of AssetModelPropertyDefinition objects

Required: No

assetModelCompositeModelType

The composite model type. Valid values are AWS/ALARM, CUSTOM, or AWS/L4E_ANOMALY.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: [^\u0000-\u001F\u007F]+

Required: Yes

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

composedAssetModelId

The ID of a component model which is reused to create this composite model.

Type: String

Length Constraints: Minimum length of 13. Maximum length of 139.

Pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$|^externalId:[a-zA-Z0-9][a-zA-Z_\-0-9.:]*[a-zA-Z0-9]+
