Basically there are 2 parts SCORM Version 1.2: the Run-Time Environment and the Content Aggregation Model. The Run-Time Environment specifies how content should behave once it has been launched by the LMS. The Content Aggregation Model specifies how you should package your content so that it can be imported into an LMS. This involves creating XML files that an LMS can read and learn everything it needs to know about your content.
