As shown in Figure 3, in the SCORM run-time environment Siebel Training launches the Sharable Content Object (SCO), which is a collection of one or more assets.
The Launch mechanism presents a common way for the LMS to start Web-based learning resources. This mechanism defines the procedures and responsibilities for the establishment of communication between the delivered learning resource and the LMS. The communication protocols are standardized through the use of a common API.
The API is the communication mechanism used to inform the LMS of the state of the learning resource (for example, initialized, finished, or in an error condition). It is also used to get and set data (score, time limits, and so on) between the LMS and the Sharable Content Object (SCO).
A Data Model is a standard set of data elements used to define the information being communicated, such as, the status of the learning resource. In its simplest form, the data model defines elements that both the LMS and SCO are expected to know about. The LMS must maintain the state of required data elements across sessions, and the learning content must use only these predefined data elements if reuse across multiple systems is to occur.
