SCORM 2004 introduced sequencing, navigation rules, and a structured data model that fundamentally changed how Learning Management Systems interpret and control eLearning content. While SCORM 1.2 focused on web-based tracking, SCORM 2004 expanded the specification with run-time improvements, completion and success logic, and rule-based activity flow.

In this 12-part technical series, we explore SCORM 2004 architecture, the Run-Time Environment, the data model, imsmanifest.xml structure, sequencing rules, LMS behavior, debugging strategies, and migration considerations. Each article provides practical implementation insights for developers, LMS engineers, and eLearning architects working with SCORM-based content.

Whether you are maintaining legacy SCORM courses or designing interoperable learning systems, this series offers a clear and specification-aware deep dive into SCORM 2004.
