Variables de plantilla

Template variables allow for integration with other systems by exposing information about the user's context in a way that makes creating URLs to pass information to these systems easy.

Template variables are represented by a series of values given a special syntax. This syntax is
@X@object.attribute@X@. When used, these variables are expanded when rendered into their corresponding values. Within the UI, they can be used in portal modules and within the body of content items in courses.

Note that not all of these variables will resolve on all pages, For example, if the page is not inside a course, there will be no course-related variables available.
