ADL Open Source LRS vs SCORM Cloud LRS

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.

SCORM Cloud LRS captures xAPI statements from online activities and learning experiences that take place in person. It has passed the ADL LRS Test Suite and accepts externally generated xAPI statements without charging by statement volume. Activity providers can be configured to forward statements to other LRSs. The SCORM Cloud player supports xAPI, cmi5, SCORM, and AICC content, and SCORM and AICC registration data can be converted into xAPI statements stored in the LRS. An API supports integrating course hosting, delivery, learner tracking, and reporting into other applications. The service runs in the cloud and is available through web and API platforms. Its free, non-time-based Trial allows 3 courses, up to 5GB of storage, and 10 resettable registrations. Paid plans range from Tester at $40 a month to Ultra at $5,000 a month, with registration allowances varying by plan. Rustici offers support by phone, email, and Knowledge Base. The company was founded in 2002 and is based in Franklin, Tennessee.
