.. _The edX-Insider course.xml File: ################################### The edX-Insider ``course.xml`` File ################################### The courseware for `edX-Insider`_ is defined in the `course.xml`_ file and follows the organization described in :ref:`The Courseware Structure`. .. contents:: :local: :depth: 1 ***************************** edX-Insider Course Hierarchy ***************************** The edX-Insider courseware is organized into chapters, sequentials, and verticals. For example, the following XML defines the first chapter, sequential, and vertical in the course. .. code-block:: xml The vertical ``Week's Overview`` contains an HTML component that references the file ``Week_overview`` in the ``HTML`` directory. Learners see this content in the Learning Management System as follows. .. Image:: ../Images/Insider-first-image.png :alt: The HTML component as a learner sees it. ********************************* Sequentials that Contain XBlocks ********************************* One advantage of OLX (open learning XML) is the flexibility it allows in how you organize your course. For example, edX-Insider demonstrates that you can nest XBlocks and problems directly in a sequential, without the need for a vertical. This streamlines the course creation process while maintaining consistency in how students interact with courseware. The following example XML defines a sequential that has, as children, an HTML XBlock, a reference to a vertical that is defined in another file, and a reference to a problem defined in another file. .. code-block:: xml
