Sorry for the late reply @Zachary_Trabookis…
Yes, I agree that there are some parts of OARS which are very cool. We could definitely trade tracking logs for xAPI events – though I’m not as critical of tracking logs as others. xAPI events would be more standard, consistent and easier to work with, but we could achieve similar results with some very basic tracking log filters. I think that OARS really makes sense if you want to deploy a learning record store (LRS) next to your analytics reporting stack. When Ralph becomes compliant with the LRS standard, this should allow you to aggregate Moodle and Open edX data. But I fail to see the purpose of an LRS outside of that niche scenario. Moreover, my understanding is that OARS makes it harder to connect events and MySQL data, whereas in Cairn it’s trivial to run JOIN statements between these two sources of content.
But let’s discuss this further in the data working group
