Delete asset models, component models, and interfaces in AWS IoT SiteWise

You can use the AWS IoT SiteWise console or API to delete an asset model, component model, or interface.

Before you can delete an asset model, you must first delete all assets that were created from the asset model. Before you can delete an interface, you must first unlink it from all asset models that implement it.

When you delete an asset model or interface, its status is DELETING until the changes propagate. For more information, see Asset and model states. After the asset model or interface is deleted, you can't query that asset model or interface. If you do, the API returns an HTTP 404 response.

Delete an asset model, component model, or interface (AWS CLI)

You can use the AWS Command Line Interface (AWS CLI) to delete an asset model, component model, or interface.

Use the DeleteAssetModel operation to delete an asset model, component model, or interface. Specify the following parameter:

• assetModelId – The ID of the asset. This is the actual ID in UUID format, or the externalId:myExternalId if it has one. For more information, see Reference objects with external IDs in the AWS IoT SiteWise User Guide.

To delete an asset model (AWS CLI)

1. Run the following command to list all assets created from the model. Replace asset-model-id with the ID or the external ID of the asset model.

   aws iotsitewise list-assets --asset-model-id asset-model-id

   For more information, see the ListAssets operation.

2. If the previous command returns any assets from the model, delete each asset. For more information, see Delete an asset (AWS CLI).

3. Run the following command to delete the asset model. Replace asset-model-id with the ID or external ID of the asset model.

   aws iotsitewise delete-asset-model --asset-model-id asset-model-id

Important

To avoid deleting an asset model that was concurrently updated since the last read operation, you must define a conditional delete request. See Optimistic locking for asset model writes.
