The Manifest Basics Content Example (MBCE) builds foundational knowledge on the key concepts that apply to a Manifest and the Sharable Content Object Reference Model (SCORM) 2004 3rd Edition. A Manifest is an extensible markup language (XML) document that contains a structured inventory of the contents of a package. The Manifest is also the place where content developers define the sequencing rules of the content. SCORM 2004 3rd Edition MBCE Version 1.0 is a SCORM 2004 3rd Edition Conformant Content Aggregation Package.
