create-asset-model¶
Description¶
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 .

A unique, friendly name for the asset model.
--asset-model-description (string)
A description for the asset model.
--asset-model-properties (list)
The property definitions of the asset model. For more information, see Asset properties in the AWS IoT SiteWise User Guide .
You can specify up to 200 properties per asset model. For more information, see Quotas in the AWS IoT SiteWise User Guide .
(structure)
Contains an asset model property definition. This property definition is applied to all assets created from the asset model.
name -> (string)
The name of the property definition.
dataType -> (string)
The data type of the property definition.
If you specify
STRUCT, you must also specifydataTypeSpecto identify the type of the structure for this property.dataTypeSpec -> (string)
The data type of the structure for this property. This parameter is required on properties that have the
STRUCTdata type.The options for this parameter depend on the type of the composite model in which you define this property. Use
AWS/ALARM_STATEfor alarm state in alarm composite models.unit -> (string)
The unit of the property definition, such as
NewtonsorRPM.type -> (structure)
The property definition type (see
PropertyType). You can only specify one type in a property definition.attribute -> (structure)
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 -> (structure)
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 -> (structure)
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)
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 .

name -> (string)
The friendly name of the variable to be used in the expression.

nameif 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 -> (structure)
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)
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 .

Contains expression variable information.
name -> (string)
The friendly name of the variable to be used in the expression.
value -> (structure)
The variable that identifies an asset property from which to use values.
propertyId -> (string)
The ID of the property to use as the variable. You can use the property
nameif 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 -> (structure)

window.tumbling -> (structure)
The tumbling time interval window.
interval -> (string)
The time interval for the tumbling window. Note that
wrepresents weeks,drepresents days,hrepresents hours, andmrepresents minutes. AWS IoT SiteWise computes the1winterval the end of Sunday at midnight each week (UTC), the1dinterval at the end of each day at midnight (UTC), the1hinterval 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.

--cli-input-json | --cli-input-yaml (string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.
--generate-cli-skeleton (string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples¶
To create an asset model
The following create-asset-model example creates an asset model that defines a wind turbine with the following properties:
Serial number - The serial number of a wind turbine
Generated power - The generated power data stream from a wind turbine
Temperature C - The temperature data stream from a wind turbine in Celsius
