Project Element

A project element defines the parameter values to use when you run a specific

mapping

in the project. A project element also defines the parameter values to use when you run any

mapping

that uses the objects in the project.

The project element defines the project in the Model repository that contains objects that use parameters. The project element can include a workflow or mapping. You cannot include transformation, mapplet, or data object elements in the project element.

The following table describes the elements that a project element can contain:

Element Name	Description
folder	Defines a folder within the project. Use a folder element if objects are organized in multiple folders within the project. A folder element can contain a mapping or a workflow element, or another folder element.
mapping	Defines a mapping within the project that uses parameters. A mapping element contains one or more parameter elements that define parameter values for the mapping or for any non-reusable transformation, mapplet, or data object in the mapping that accepts parameters.

When you run a mapping with a parameter file that defines parameter values in a project top-level element, the Data Integration Service applies the parameter values to the specified mapping within the project.

For example, you want the Data Integration Service to apply the parameter defined by "MyMapping_Param" when you run the mapping "MyMapping". You can define the parameter in the parameter file using the following elements:

<project name="MyProject">

  <!-- Apply this parameter value to mapping "MyMapping" in project "MyProject". -->
  <mapping name="MyMapping">
    <parameter name ="MyMapping_Param">Param_value</parameter>
  </mapping> 
  
</project>
