Retrieves information about an asset composite model (also known as an asset component). An AssetCompositeModel is an instance of an AssetModelCompositeModel. If you want to see information about the model this is based on, call DescribeAssetModelCompositeModel.

Request Syntax


GET /assets/assetId/composite-models/assetCompositeModelId HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

assetCompositeModelId

Required: Yes

Response Elements

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

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

actionDefinitions

The available actions for a composite model on this asset.

Type: Array of ActionDefinition objects

assetCompositeModelDescription

A description for the composite model.

Type: String

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

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

assetCompositeModelExternalId

An external ID to assign to the asset model.

If the composite model is a component-based 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

Length Constraints: Minimum length of 2. Maximum length of 128.

Pattern: [a-zA-Z0-9_][a-zA-Z_\-0-9.:]*[a-zA-Z0-9_]+

assetCompositeModelId

The ID of a composite model on this asset.

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}$

assetCompositeModelName

The unique, friendly name for the composite model.

Type: String

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

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