Aspects Extensibility

@Cristhian Garcia

Cristhian is going to update us on various extension points!

  • Two dashboards in Aspects now: Open edX Admin Dashboard and the Instructor Dashboard (Rory the DBA has been focusing on this one).

  • #69 added ability to maintain custom dashboards/charts etc assets for Superset, which can also be shared with the community.
    People can create them using the Superset UI, export them to a zip file, and then use the script tool created by this PR to generate a tutor patch for their custom assets.

  • #70 added dbt to Aspects, so people write their own performant, complex queries.

  • #99 adds ability to run database migrations on clickhouse, so we can maintain changes between versions, and users can add their own tables, fields, etc.

Aspects in LMS update

@Cristhian Garcia

Cristhian is also going to update us on some very early work he did to get Superset data and charts to display in the LMS via XBlock Asides, and share what he’s learned.


  • XBlock Asides are old, and not well-supported by newer things, like REST APIs.

  • We need to be mindful of performance – cannot be hitting Superset every time we load a block.

  • Asides are not supported in Studio, so we’d have to use the LMS for this visualisation.

 Action items

@Brian Mesick write skeleton documentation so we can begin fleshing things out. We will need to update the “getting started” docs, but also want high level architecture and data flow / pipeline docs. (From last meeting. Update: still needs to be done, maybe I’ll have a start by Weds)
@Brian Mesick look into Caliper recertification. edX handled this in the past, it seems to require some kind of formal relationship with 1EdTech, I’ll ask around Axim to see if anyone knows (From last meetings. Update: Axim has an account, when we have a beta candidate for Aspects I’ll update the demo server with it and use it to re-certify or generate a list of issues)
