Step 25 – Review Table of Mandatory Data Elements

Time to review the list of mandatory SCORM 1.2 data elements that I created in Step 19. The table shows:

• the name of the data element;
• is it readable;
• is it writeable;
• the format of the data; and
• the initial value for the element.

You’ll see that I’ve added a ‘dummy’ element called adlcp:masteryscore to store the value (if any) set in the IMS manifest file that’s used when setting cmi.core.lesson_status after LMSFinish() is called. You could argue that this should really be stored in the (optional) cmi.student_data.mastery_score data element, but I don’t want to support any of the optional data elements right now.

You’ll also see that I’ve highlighted 4 elements that require initialization from data that’s stored in the LMS – either student information (name and student ID) or data from the IMS manifest file that’s read during the upload and installation of the content aggregation (course) package. Handling these values will be the subject of my next post.
