Creates an asset model from specified property and hierarchy definitions. You create assets from asset models. With asset models, you can easily create assets of the same type that have standardized definitions. Each asset created from a model inherits the asset model's property and hierarchy definitions. For more information, see Defining asset models in the AWS IoT SiteWise User Guide.

The ID of the asset model hierarchy. This ID is a hierarchyId.
name (string) -- [REQUIRED]
The name of the asset model hierarchy that you specify by using the CreateAssetModel or UpdateAssetModel API operation.
childAssetModelId (string) -- [REQUIRED]
The ID of the asset model. All assets in this hierarchy must be instances of the childAssetModelId asset model.
list
The composite asset models that are part of this asset model. Composite asset models are asset models that contain specific properties. Each composite model has a type that defines the properties that the composite model supports. Use composite asset models to define alarms on this asset model.
(dict) --
Contains information about a composite model in an asset model. This object contains the asset property definitions that you define in the composite model.
name (string) -- [REQUIRED]
The name of the composite model.
description (string) --
The description of the composite model.
type (string) -- [REQUIRED]
The type of the composite model. For alarm composite models, this type is AWS/ALARM.
properties (list) --
The asset property definitions for this composite model.
(dict) --
Contains information about an asset model property.
id (string) --
The ID of the asset model property.
name (string) -- [REQUIRED]
The name of the asset model property.
dataType (string) -- [REQUIRED]
The data type of the asset model property.
dataTypeSpec (string) --
The data type of the structure for this property. This parameter exists on properties that have the STRUCT data type.
unit (string) --
The unit of the asset model property, such as Newtons or RPM.
type (dict) -- [REQUIRED]
The property type (see PropertyType).
attribute (dict) --
Specifies an asset attribute property. An attribute generally contains static information, such as the serial number of an IIoT wind turbine.
defaultValue (string) --
The default value of the asset model property attribute. All assets that you create from the asset model contain this attribute value. You can update an attribute's value after you create an asset. For more information, see Updating attribute values in the AWS IoT SiteWise User Guide.
measurement (dict) --
Specifies an asset measurement property. A measurement represents a device's raw sensor data stream, such as timestamped temperature values or timestamped power values.
transform (dict) --
Specifies an asset transform property. A transform contains a mathematical expression that maps a property's data points from one form to another, such as a unit conversion from Celsius to Fahrenheit.
expression (string) -- [REQUIRED]
The mathematical expression that defines the transformation function. You can specify up to 10 variables per expression. You can specify up to 10 functions per expression.
For more information, see Quotas in the AWS IoT SiteWise User Guide.
variables (list) -- [REQUIRED]
The list of variables used in the expression.
(dict) --
Contains expression variable information.
name (string) -- [REQUIRED]
The friendly name of the variable to be used in the expression.
value (dict) -- [REQUIRED]
The variable that identifies an asset property from which to use values.
propertyId (string) -- [REQUIRED]
The ID of the property to use as the variable. You can use the property name if it's from the same asset model.
hierarchyId (string) --
The ID of the hierarchy to query for the property ID. You can use the hierarchy's name instead of the hierarchy's ID.
You use a hierarchy ID instead of a model ID because you can have several hierarchies using the same model and therefore the same propertyId. For example, you might have separately grouped assets that come from the same asset model. For more information, see Asset hierarchies in the AWS IoT SiteWise User Guide.
metric (dict) --
Specifies an asset metric property. A metric contains a mathematical expression that uses aggregate functions to process all input data points over a time interval and output a single data point, such as to calculate the average hourly temperature.
expression (string) -- [REQUIRED]
The mathematical expression that defines the metric aggregation function. You can specify up to 10 variables per expression. You can specify up to 10 functions per expression.
For more information, see Quotas in the AWS IoT SiteWise User Guide.
variables (list) -- [REQUIRED]
The list of variables used in the expression.
(dict) --
Contains expression variable information.
name (string) -- [REQUIRED]
The friendly name of the variable to be used in the expression.
value (dict) -- [REQUIRED]
The variable that identifies an asset property from which to use values.
propertyId (string) -- [REQUIRED]
The ID of the property to use as the variable. You can use the property name if it's from the same asset model.
hierarchyId (string) --
The ID of the hierarchy to query for the property ID. You can use the hierarchy's name instead of the hierarchy's ID.
You use a hierarchy ID instead of a model ID because you can have several hierarchies using the same model and therefore the same propertyId. For example, you might have separately grouped assets that come from the same asset model. For more information, see Asset hierarchies in the AWS IoT SiteWise User Guide.
window (dict) -- [REQUIRED]
The window (time interval) over which AWS IoT SiteWise computes the metric's aggregation expression. AWS IoT SiteWise computes one data point per window.
tumbling (dict) --
The tumbling time interval window.
interval (string) -- [REQUIRED]
The time interval for the tumbling window. Note that w represents weeks, d represents days, h represents hours, and m represents minutes. AWS IoT SiteWise computes the 1w interval the end of Sunday at midnight each week (UTC), the 1d interval at the end of each day at midnight (UTC), the 1h interval at the end of each hour, and so on.
When AWS IoT SiteWise aggregates data points for metric computations, the start of each interval is exclusive and the end of each interval is inclusive. AWS IoT SiteWise places the computed data point at the end of the interval.
string
A unique case-sensitive identifier that you can provide to ensure the idempotency of the request. Don't reuse this client token if a new idempotent request is required.
This field is autopopulated if not provided.
