The specification for SCORM 1.3 was released for Beta testing in June 2003. The full release now called SCORM 2004 was released in January 2004.
- Several of the course-to-server data sets have been modified.
- The primary modification is expansion to describe course/unit sequencing. This refers to what content is served next based on the student's performance.
- The new version also allows for assets (e.g. graphics, glossaries, etc.) that may be shared between different SCOs (Shareable Content Objects). This applies, for example, to a glossary that is available to all the objects.
- For an LMS to be SCORM 2004 complient they will need to change their current architecture. This is why you don't see very many SCORM 2004 complient LMSs.
