xAPI integration

I see that there was some interest in leveraging xAPI as depicted here: https://github.com/edx/xapi-events I also found a deprecated attempt at doing this here: https://github.com/openfun/openedx-xapi but have found no other sources. Is there a current project being run or completed that hasn’t been published to the Open-edX GitHub page, or has this this effort been canceled?

While on the analytics subject, I know there was also interest in Caliper through https://github.com/ucsd-ets/openedx-caliper-tracking
