Objects and keywords	Description
OBJECT-PATH	The path of the CIM class or CIM instance to be referenced.
MACHINENAME	The network-identifiable name of the machine where the referenced WMI class, instance, or namespace resides.
CLASS-NAME	Identifies a CIM class name.
INSTANCE-KEY	Uniquely identifies the instance of a given CIM class.
KEY-VALUE-LIST	List of property names and their values, separated by a ",". Each property value pair is represented in propertyName=value format.
PROPERTY-NAME	Identifies the name of a property of the CIM class.
