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 IoT SiteWise User Guide.
If you remove a property from a composite asset model, 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 - UpdateAssetModelCompositeModelrequest with the entire existing property removed.
- Submit a second - UpdateAssetModelCompositeModelrequest that includes the new property. The new asset property will have the same- nameas the previous one and IoT SiteWise will generate a new unique- id.
