Action item Question

@Vladimir Susloparov

• xAPI Anonimus User ID & event-routing-backends feature modification.

• Connection between EDX and xAPI data.

• Let’s postpone this until a time @Vladimir Susloparov can attend.

xAPI next steps

@Edward Zarecor

• The ADL team recommended that we consider creating an xAPI profile for Open edX data

• They also recommended adopting the CMI5 profile which:

  • is a general profile focused on the lifecycle of interactions with AUs – assignable units.

  • would provide strong interoperability for core learning data around things like “time on task,” completion, pass/fail.

• Possible stories for an xAPI sprint:

  • implementing the xAPI video profile for the existing event routing back end mapping and adding conformance testing

  • modeling hint data as xAPI references rather than baking that data into core Open edX problem statements

  • creating a v1 xAPI profile for Open edX events that extends existing profiles like CMI5 and video.

• Discussions

  • Ideally if we created an Open edX profile, it could benefit from and extend the GaiaX LMS profile that is in the works.

  • How would we handle the impedance mismatch between our events and xAPI in only the video space?

    • Seems like the right choice would be to extend to the “Interacted” verb.

    • Some examples of events that don’t correspond to existing Video profile verbs are transcript hide and show. We don’t think these interaction types are currently covered by the profile either.

    • Ideally we could get the interaction types adopted upstream if they are important.

Replaying events from the tracking logs to segment

@John Baldwin (Unlicensed)

• Is there an existing mechanism for replaying a subset of event to segment.io?

• The use case is that for some period events were not forwarding.

• This isn’t a platform capability

• The best choice would be tools that could process the raw logs files and forward events to segment.
