Concepts

This page provides background information required to complete the exercises in this tutorial.

In this tutorial we will use a powerful mechanism for reusing and customizing existing content called method content variability. The original content will not be affected by our operations, however, we will build upon it as a base for defining our new content. Then we will demonstrate that modifications to the base content are automatically inherited by variable content in dependent plug-ins. When the resulting configuration is published as a Web site or exported, all of our customization will be resolved into a single resource.

There are four types of method content variability and in this tutorial we will use all of them to customize existing content. The following are the four ways for using method content variability:
  • Contributes
  • Extends
  • Replaces
  • Extends and Replaces
