scope:

This book defines the SCORM RTE model, which details the requirements for launching content objects, establishing communication between LMSs and SCOs, and managing the tracking information that can be communicated between SCOs and LMSs. In the context of SCORM, content objects are either: • SCOs, which communicate during run-time, or • Assets, which do not communicate during run-time. The SCORM RTE book describes a common content object launch mechanism, a common communication mechanism between content objects and LMSs, and a common data model for tracking a learner's experience with content objects. These aspects create an environment where several of the ADL "-ilities" are satisfied. For example, content objects that communicate through the standardized communication mechanism can be moved from LMS to LMS without modification to their communication attempts; this increases learning object portability and durability, thereby lowering the cost of development, installation and maintenance. The SCORM RTE defines a model that picks up at the point when a specific content object has been identified for launch. The actual identification of the content object to be launched is out of scope of this book and can be found in the SCORM SN book [11].
