REference for SCORM 2004 data model

Where do I 开发者_高级运维find the SCORM 2004 run time data model details?Looking for pdf which explains each data model in detail. Any reference?

There is also an online reference chart that can be a bit easier on the eyes and contains accurate information for all of the SCORM versions and editions available at http://www.scorm.com/scorm-explained/technical-scorm/run-time/run-time-reference/

Here is the best one I've found: http://www.scorm.com/wp-content/assets/scorm_ref_poster/RusticiSCORMPoster-large.pdf

The official SCORM 2004 documentation is available on the ADL website. It includes detailed descriptions of the data model. http://www.adlnet.gov/Technologies/scorm/SCORMSDocuments/2004%204th%20Edition/Documentation.aspx
