What Jupiter is
Jupiter is an open-source Learning Record Store for data in the xAPI and Caliper specifications. Its repository ingests Experience API and Caliper API payloads, and the maker describes it as scalable and fault tolerant. Jupiter includes Metis, an open-source interface for building queries and reviewing metrics. Metis presents results as tables and visualizations, exports them in multiple formats, and monitors cluster health with notifications about network or hardware failures. Jupiter can be self-hosted, while Transcordia also offers Jove, a hosted Learning Record Store built on Amazon Web Services and powered by Jupiter. The maker says Jove can handle tens of thousands of learning events per second. Jove has a free allowance of up to 1 million events per year; usage above that is priced at $1 per month for each 10,000 events per month after the allowance. Jupiter uses the MIT license, and the maker invites coding contributions and pull requests. Its stated audience includes educational institutions and research organizations.
