Notes

cmi5 Narrative LMS flow

The group updated the spec references to the talking points for the the LMS Process flow chart (one section per box) as follows:

Import Course Structure**

• There are 3 import scenarios:
• ZIP file with media & manifest
• ZIP file with manifest only (referencing media)
• manifest only (referencing media)
• Copy media (if present in Zip file) and read manifest (cmi5.xml) file
• Get content metadata (URLs, Titles, launch parameters)
• Get content hierarchy (content grouped in blocks)
• Get course/block completion rules (called “moveOn” criteria)

See Sections:

• 6.1 Course Structures
• 13.0 Course Structure Data Requirements
• 14.0 Course Package

Assign Enrollment

• Create a unique registration id for each learner enrollment in the course.

See Sections:

• 3.0 Definitions – Registration
• 8.1 Launch Method

Check (initial) moveOn Rules

Upon enrollment the LMS needs to determine if any content (AU’s) has a default value for moveOn or is set to “NotApplicable”. This will result in

• Individual AU’s being set to “Satisfied” (moveOn rule met)
• Entire course being set to “Satisfied” (moveOn rule met) if all AU’s Satisfied

It should also be noted that course developers may unintentionally create courses with all default settings that are automatically (completely) satisfied on enrollment. (See Common Mistakes (#4) - http://aicc.github.io/CMI-5_Spec_Current/mistakes/ )

See Sections:

• 13.1.4 AU Metadata - moveOn
• 9.3.9 Satisfied

Determine Launch Mode

Your LMS may have business rules for the following learner scenarios

• Launch content initially
• Re-entering unfinished content
• Reviewing Content that has previously been completed
• Previewing Content (without being evaluation)

Prior to launching content, you will need to create a “state document” specific to the launch. Based on each scenario you will need to set the launchMode (in the state document) to the correct value (Normal, Review, or Browse).
See Sections:

• 10.0 xAPI State Data Model

Prepare for Launch

LMS must create a state document with launch parameters. See Section - 10.0 xAPI State Data Model

LMS must create an agent profile document with learner language preference specified (and may provide an audio on/off preference also). See Section -11.0 xAPI Agent Profile Data Model

LMS sends Launched Statement. See Section 9.3.1 Launched

LMS issues an abandoned statement for previously launched AU sessions that were “abnormally” terminated. See Section - 9.3.6 Abandoned

Content Launch

LMS must have a service (Fetch URL) to provide an authentication token for access to the LRS. See Section - 8.2 Authorization Token Fetch URL. LMS creates a URL launch line with LRS connect string parameters (including a reference to the Fetch URL). See Section - 8.1 Launch Method. The LMS launches the content using one of the following methods

1. Redirects the Browser window to the launch URL
2. Redirect to an iFrame to the launch URL
3. Spawns a new window

See Section 13.1.4 AU Metadata - launchMethod

Evaluate AU Output

LMS Evaluates Statements from the AU session for conformance to the rules (as they are sent to the LRS)

• Check for Initialize/Terminate
• Validate cmi5 defined statement rules
• Valid cmi5 allowed statement requirements
• Check for Post terminate statements
• LMS detects AU exit (e.g. return URL / Window Close)

See Sections:

• 7.1.3 Types of Statements
• 9.3 Verbs

AU Satisfied (verify MoveOn criteria) LMS checks if moveOn criteria was met for the AU (As set by the LMS in the State document).
See Sections:

• 10.0 xAPI State Data Model – moveOn
• 13.1.4 AU Metadata – moveOn

Block Satisfied (verify MoveOn criteria)

LMS checks other AUs and Block within the current block to determine if the block is satisfied (per the moveOn criteria defined in the course structure).
This includes traversing the hierarchy for nested blocks.

See Sections:

• 9.3.9 Satisfied
• 13.1.2 Block Metadata

Course Satisfied LMS verifies that all Blocks and their children are satisfied and that any AU’s at the root level of the course are completed. See Sections:

• 9.3.9 Satisfied
