One of the great parts of the SCORM specification is that its extensibility allows vendors to add additional functionality without breaking the standard or requiring other vendors to use a proprietary technology. Rustici Software has extended the SCORM meta-data specification to allow content vendors added control over how the SCORM Engine will deliver their content. These added parameters determine such things as the default window size, which navigational controls are available and how the player should behave when a SCO exits. The SCORM Engine meta-data extensions can be divided into three broad categories:
The table below contains a complete list of the available parameters.

yes/no |
3.2 |
Exit Actions |
These setting control what action the SCORM Player will take when a SCO exits. Some possible actions include going to the next SCO, displaying a message and exiting the course (see description of the Exit Type data type for more detail). There are three factors the SCORM Player looks at when determining the action to take when a SCO exits, the position of the SCO in the course (is it in the middle, or is it the last SCO), the state of the SCO/Course, and the SCORM exit type specified by the SCO. The following parameters allow you to adjust the SCORM Players behavior in each of these possible scenarios. Note that these parameters only take affect when the content originates an exit action by calling LMSFinish before the user initiates an exit action by using a navigational control in the SCORM Player. |
Container |

Reset RT Time |
Defines when to reset Runtime Data. |
Reset RunTime Data Time Type |
There is not data associated with container elements, they are simply placeholders to facilitate logical grouping of other elements.
The yes/no data type can have two values: yes represents the affirmative and no represents the negative.
The positive integer data type is a string that represents an integer greater than or equal to zero.
The launch type data type represents methods by which new windows can be launched. The possible values are:
frameset - Launches the item in a frameset. When applied to a SCO, this will result in the standard SCORM Player configuration pictured above. When applied to the SCORM Player itself it will launch the player inline rather than popping it in a new window.
new window - Launches the item in a new window.
new window,after click - Launches the item in a new window after forcing the user to click on an explicit link. This setting can be useful for circumventing popup blockers.
new window without browser toolbar - Launches the item in a new window without the standard browser toolbar.
The exit type data type represents actions the SCORM Player can take after a SCO exits. The possible values are:
exit,no confirmation - Simply close the SCORM Player and return to the HLC
exit,confirmation - Ask the learner if he wishes to exit the course, if so, return to the HLC, if not, display a message page.
continue - Take the learner to the next SCO. If applied to the final SCO, display a message page.
message page - Display a message page. The SCORM Player determines what message to display based on the current state of the player.
do nothing - The SCORM Player will take no action.
The status display data type represents the various ways in which the SCORM Player can display the status of SCOs to the user. The possible values are:
success only - Only success status is presented to the user.
completion only - Only completion status is presented to the user.
separate - Both success and completion status are presented to the user as separate indicators.
combined - Success and completion status are presented to the user as one combined metric.
none - No SCO-level status is presented to the user.
The score rollup data type represents the various ways in which the SCORM Player can rollup scores to the course level. The possible values are:
score provided by course - Useful for single-SCO courses, this parameter simply transfers the score provided by the first SCO in the course to the course-level.
average score of all units - Sum up all the scores that were provided and divide by the total number of SCOs in the course.
average score of all units with scores - Sum up all the scores that were provide and divide by the number of units that actually reported scores.
fixed average - Sum up all the scores that were provided and divide by a fixed number (as specified in the Number Of Scoring Objects setting).
The status rollup data type represents the various ways in which the SCORM Player can rollup status to the course level. The possible values are:
status provided by course - Useful for single-SCO courses, this parameter simply transfers the status provided by the first SCO in the course to the course-level.
complete when all units complete - The course is considered complete when all of the SCOs have achieved completion. This means that the lesson status value is either failed, completed or passed.
complete when all units satisfactorily complete - The course is considered complete when all of the SCOs have achieved completion in a satisfactory manner. This means that the lesson status value is either completed or passed.
complete when threshold score is met - The course is considered complete when its rolled up score (as determined by the Score Rollup Type) exceeds a certain threshold (specified in the Threshold Score For Completion parameter).
complete when all units complete and threshold score is met - This course is considered complete when all of the SCOs have achieved completion (lesson status = failed, completed, or passed) and when its rolled up score exceeds the threshold specified in the Threshold Score For Completion parameter.
Represents the various ways to handle menu item options that are not valid
show - Invalid menu items are visible but will result in an invalid action message.
hide - Invalid menu items are not visible.
disable - Invalid menu items are visible but do nothing.
Represents when to reset runtime data
never - SCORM Engine will never reset CMI runtime data.
when exit is not suspend - Only preserves CMI runtime data if exit is suspend.
on each new sequencing attempt - The SCORM engine will reset the CMI runtime data every time the SCORM 2004 sequencing algorithms dictate that a new attempt should begin.
The table below lists the default value for all SCORM Engine metadata parameters.

The SCORM Engine extensions are specified within the top-level meta-data section of the manifest which affects the manifest as a whole. The extension elements are placed in the technical element of standard SCORM metadata in a container element called HSTMConfiguration. The directory that holds the file you are reading also contains a sample metadata document along with an XML Schema (xsd) describing the XML binding of these parameters (which you can use to validate the format of your extensions). When including these extensions, pay special attention to the namespace declarations at the top of the sample meta-data file and the hstm prefix on the HSTMConfiguration element. These declarations are necessary to preserve SCORM compatibility.
