xAPI Version Compatibility in cmi5

The group continued its discussion about how to handle xAPI version compatibility/references in cmi5.

Course Structure – AU properties – add xAPI version to metadata

  • AU level property (minimum supported version)
    • If value not present:
      • xAPI 1.0.x is default – 1.0.x must be used
      • AU will do what it can - “good luck” - may or may not work
      • AU will Support any version of xAPI (will negotiate) –
    • Some AU’s could negotiate
    • Could be list of supported vs a minimum supported
    • Provides a mechanism to deal with incompatible versions.
    • LMS Quality of implementation issue for multiple xAPI version support

xAPI Profile Server – Versions are present in IRI’s but no xAPI versions listed.

lMS – LMS normalizes AU statements to its LRS xAPI (e.g. 2.0 headers).

AU – sends xAPI 1, 2, etc.

Additional properties SHOULD* NOT be added to Statements unless explicitly allowed by this specification.

Note: The LRS is recommended to reject Statements containing additional properties. Additional properties in Statements would mean that the Statement would not be interoperable with all LRSs.
