Jupiter

Jupiter is an open-source Learning Record Store (LRS) for learning activity data using the xAPI and Caliper specifications. Its cloud-based repository ingests Experience API and Caliper API payloads; the maker describes it as scalable and fault tolerant. Jupiter includes Metis, an open-source interface for building queries and reviewing metrics. Metis displays results as visualizations and tables, exports them in multiple formats, and monitors cluster health with notifications for network or hardware failures. Jupiter can be self-hosted. Transcordia also offers Jove, a hosted LRS on Amazon Web Services powered by Jupiter, which the maker says can handle tens of thousands of learning events per second. Jove allows up to 1 million events per year at no charge; usage above that allowance is listed at $1 per month for each 10,000 events per month. The repository uses the MIT license, and the maker invites coding contributions and pull requests. Its stated audience includes educational institutions, research organizations, and others interested in learning record stores.

Jupiter combines learning-event storage with Metis query, reporting, and monitoring tools. Teams can self-host it or consider Jove, whose listed pricing charges for usage beyond its annual free allowance.

Jupiter may suit educational institutions, research organizations, and others interested in learning record stores. Its self-hosted option and open-source license may also appeal to teams that want to contribute code.
