Ralph can be considered versatile since at some point it is log-content-agnostic: most commands will work as expected without transforming logged events content or format.
But on the other side, Ralph is a tool dedicated to learning events processing so we’ve implemented key features related to learning events validation and conversion. For now, we mostly focus on two learning events standards: Open edX and xAPI.
Data validation and serialisation/de-serialisation are achieved using pydantics models that are documented in the following subsections:
- Open edX
- xAPI (work in progress)
