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.

Element Name Read Write Type Initial Value
cmi.core._children   Str 255 ‘student_id,student_name,
Student Information from the LMS
cmi.core.student_id   Identifier Initialized with data from the LMS

cmi.core.score.raw Decimal/Blank An empty string

    Thank you very much for posting your adventures with the SCORM RTE. I found this guide to be fast, friendly and very helpful. I also visited your portal on LM-Light. I love the idea.

    I was able to set up a chat room where students could visit at a dgtaenised time either every day or once a week. I did not see an option for linking Skype. How are you able to use Skype through Moodle?
