Ralph
Ralph is an open-source learning analytics toolbox delivered as an LRS HTTP API server, command-line interface, and library. It runs through an API, on Linux, or as a self-hosted deployment. Ralph follows xAPI specification 1.0.3, but xAPI 2.0 is not supported. Its LRS stores data in Elasticsearch, MongoDB, or ClickHouse. The library documents connections to OVH Log Data Platform, OpenStack Swift, Amazon S3, filesystems, other LRS systems, and WebSockets. The API server supports HTTP Basic authentication and OpenID Connect over OAuth 2.0, either separately or together. Statement access can be restricted by authority, and user scopes can limit endpoints or functions; both controls are off by default. Received xAPI statements can be forwarded to other LRS servers with configurable retries and timeouts. Sentry monitors the LRS server and CLI. The CLI converts selected OpenEdX events to xAPI statements. Ralph is distributed as a Python package and Docker image under the MIT License.
