DescribeAssetModel

Retrieves information about an asset model.

Request Syntax

GET /asset-models/assetModelId?assetModelVersion=assetModelVersion&excludeProperties=excludeProperties HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

assetModelId

The ID of the asset model. This can be either the actual ID in UUID format, or else externalId: followed by the external ID, if it has one. For more information, see Referencing objects with external IDs in the Amazon IoT SiteWise User Guide.

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

assetModelVersion

The version alias that specifies the latest or active version of the asset model. The details are returned in the response. The default value is LATEST. See Asset model versions in the Amazon IoT SiteWise User Guide.

Pattern: ^(LATEST|ACTIVE)$

excludeProperties

Whether or not to exclude asset model properties from the response.

Request Body

The request does not have a request body.

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The response returns the following HTTP headers.

eTag

The entity tag (ETag) is a hash of the retrieved version of the asset model. It's used to make concurrent updates safely to the resource. See Optimistic locking for asset model writes in the Amazon IoT SiteWise User Guide.

See Optimistic locking for asset model writes in the Amazon IoT SiteWise User Guide.

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

The following data is returned in JSON format by the service.

assetModelArn

The ARN of the asset model, which has the following format.

arn:${Partition}:iotsitewise:${Region}:${Account}:asset-model/${AssetModelId}

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1600.

Pattern: ^arn:aws(-cn|-us-gov)?:[a-zA-Z0-9-:\/_\.]+$

assetModelCompositeModels

The list of built-in composite models for the asset model, such as those with those of type AWS/ALARMS.

Type: Array of AssetModelCompositeModel objects

assetModelCompositeModelSummaries

The list of the immediate child custom composite model summaries for the asset model.

Type: Array of AssetModelCompositeModelSummary objects

assetModelCreationDate

The date the asset model was created, in Unix epoch time.

Type: Array of AssetModelHierarchy objects

assetModelId

The ID of the asset model, in UUID format.

Type: String

Length Constraints: Fixed length of 36.

Type: Array of AssetModelProperty objects

assetModelStatus

The current status of the asset model, which contains a state and any error message.

Type: AssetModelStatus object

assetModelType

The type of asset model.

  • ASSET_MODEL – (default) An asset model that you can use to create assets. Can't be included as a component in another asset model.

  • COMPONENT_MODEL – A reusable component that you can include in the composite models of other asset models. You can't create assets directly from this type of asset model.

Type: String

Valid Values: ASSET_MODEL | COMPONENT_MODEL

assetModelVersion

The version of the asset model. See Asset model versions in the Amazon IoT SiteWise User Guide.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 10.

Pattern: ^(0|([1-9]{1}\d*))$
