Represents a module’s position within a linear workflow in a module type definition.

Attributes and Elements

The following sections describe attributes, child elements, and the parent elements of the Node element.


Attribute Description


Required attribute. Represents the ID of one of the member modules of a module type definition.

Child Elements

Element Description


Required only if there is a previous node in the workflow. Represents the previous module in the workflow.

Parent Elements

Element Description


If the module represented by this Node element is not the last module in the workflow sequence, the parent of this Node element is the Node element that represents the next module in the workflow.

Composition (DataSourceModuleType)

If this module is the last module in the workflow sequence, the parent is the Composition (DataSourceModuleType) element.


Composite (DataSourceModuleType) module workflows are defined with nested Node elements. Each Node element is associated with any one of the modules listed in the MemberModules (DataSourceModuleType) element. The innermost Node element’s module is the first step of the workflow. The outermost Node element’s module is the last step in the workflow.


The following sample shows how two Node elements are nested to define a workflow. The Scheduler data source module runs first and passes its output as an input parameter to the Probe probe action module.

To see the full data source module type, see Composite (DataSourceModuleType).
