UpdateAssetModelCompositeModel

Updates a composite model and all of the assets that were created from the model. Each asset created from the model inherits the updated asset model's property and hierarchy definitions. For more information, see Updating assets and models in the AWS IoT SiteWise User Guide.

Important

If you remove a property from a composite asset model, AWS IoT SiteWise deletes all previous data for that property. You can’t change the type or data type of an existing property.

To replace an existing composite asset model property with a new one with the same name, do the following:

Submit an UpdateAssetModelCompositeModel request with the entire existing property removed.
Submit a second UpdateAssetModelCompositeModel request that includes the new property. The new asset property will have the same name as the previous one and AWS IoT SiteWise will generate a new unique id.

URI Request Parameters

The request uses the following URI parameters.

assetModelCompositeModelId

The ID of a composite model on this asset model.

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

assetModelId

The ID of the asset model, in UUID format.

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 update 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 update 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 update operation.

Valid Values: LATEST | ACTIVE

Request Body
