2.1. Run-Time Environment (RTE) Management
While the learner interacts with content objects (the learning experience), the LMS evaluates learner performance and navigation requests (refer to the SCORM SN book). When the LMS identifies an activity for delivery to the learner, the activity has a content object associated with it. The LMS will launch the content object and present it to the learner. Figure 2.1a depicts how the content structure (organization section of a manifest) can be interpreted in a tree (i.e., activity tree). The tree representation is just a different way of presenting the content structure found in the manifest (refer to the SCORM CAM book).

A common launch model addresses delivery of web-enabled content objects in the form of SCOs and assets within the context of a learning experience. This launch model enables consistency of content object launch behavior across LMSs without specifying the underlying LMS implementation. In this context, the term “LMS” is used to describe any system that provides the launch of content objects.
