SCORM™ Specifications

Stay Ahead of the Class With Great Tips To Get Prepared For College!

The specifications are a joint effort of the Aviation Industry CBT (Computer-Based Training) Committee, Institute of Electrical and Electronics Engineers, ARIADNE and the Instructional Management System Global Learning Consortium.

SCORM™ contains two specifications:

• Content Aggregation model
• Assets
  Text , HTML, Art, video, audio files, applets, plug ins etc.
   
• Sharable Content Object (SCO)
  This is a collection of assets and the necessary files that communicate with a LMS.
   
• Content aggregation
  This is a XML file that provides the asset order and the content navigation within the course (SCO)
   
• Run-Time Environment.
• The Run-Time Environment has 3 components.
  • Launch
    This is the HTTP protocol that starts a SCO.  Only a SCO can initiate communication with a LMS. A LMS is responsible for delivering the Application Programming Interface adapter to the SCO.
     
  • Application Programming Interface (API)
    The API adapter allows the SCO to send status information and exchange data. The SCO initiates all communications to the API adapter. The API adapter then communicates with the LMS. The LMS never initiates communications.
     
  • Data model
    Data elements are exchanged between the LMS and the SCO. The SCO gets and sets the data elements. The LMS only maintains the state of the data elements across user sessions.

Metadata XML files are the glue that bind everything together. XML is a World Wide Web Consortium (W3C) specification.
