ADL Open Source LRS vs Veracity Learning

ADL Open Source LRS stores learning data collected through the Experience API, or xAPI. The repository says this version conforms to IEEE 9274.1.1, also known as xAPI 2.0, and describes it as stable but intended for proof-of-concept use with a small number of users. It is free and distributed under the Apache License, Version 2.0.

Docker and Docker Compose are the recommended installation route. The deployment includes a Django web service using uWSGI, an nginx HTTP/HTTPS proxy, PostgreSQL, RabbitMQ, and Redis. OAuth is off by default; the project describes enabling it with the OAUTH_ENABLED setting and registering clients with the LRS. Optional webhooks can filter incoming statements and send matches to a client endpoint, and they are disabled by default. A webhook can include a secret used to send an HMAC hex digest in the X-LRS-Signature header. Celery handles activity metadata retrieval, statement voiding, and LRS hooks asynchronously. Database settings can be changed in settings.ini. The Docker guide describes an included Certbot container for obtaining a certificate for a public domain and restarting nginx to use it.

Veracity Learning is a learning and performance data platform built around the Experience API (xAPI) standard. Its Learning Record Store stores and retrieves xAPI statements, including signatures, binary attachments, and document stores. Analytics include default and custom dashboards, a chart builder, graph query tools, and support for common xAPI profiles. Data can be imported or exported as CSV, JSON, or URL-based data dumps, and statements can be forwarded between LRSs. The product provides an advanced search API, Veracity Query Language, and an LRS API for managing learners, lessons, and other data objects or launching content. Separate LRS instances do not share keys, analytics, or databases. Customers can use cloud-hosted SaaS in a browser or install the product on their own network; the SaaS option uses AWS by default. Veracity Lite is a free download with fewer features. Starter is listed at $100 a month, with 5 LRSs, 1GB storage, 100K–1M xAPI statements, and 25K daily API calls. The Learner Portal is a content player, not an LMS.
