URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

Required: Yes

computationModelDataBinding

The data binding for the computation model. Key is a variable name defined in configuration. Value is a ComputationModelDataBindingValue referenced by the variable.

Type: String to ComputationModelDataBindingValue object map

Key Length Constraints: Minimum length of 1. Maximum length of 64.

Key Pattern: ^[a-z][a-z0-9_]*$

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

Pattern: ^[a-zA-Z0-9 _\-#$*!@]+$

Required: No

computationModelName

The name of the computation model.

Type: String

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

Pattern: ^[a-zA-Z0-9 _\-#$*!@]+$

Required: Yes

tags

A list of key-value pairs that contain metadata for the asset. For more information, see Tagging your AWS IoT SiteWise resources in the AWS IoT SiteWise User Guide.

Type: ComputationModelStatus object

Errors

For information about the errors that are common to all actions, see Common Errors.
