There is one core builder for the presentation layer:
The Service Consumer builder makes all the operations defined in a Service Provider model available for use. It enables other builders to reference all the information provided by the service, including the input and output schemas, the operations and the associated variables. With the Service Consumer builder making the data available to the Page Automation system, you can use the entire array of Page Automation builders to generate pages. For example, the View and Form builder can reference service information, including the input and result schemas, and automatically generate complex presentation elements such as forms and list views.
