Since 2014 I was heavily involved in all stages of the development of Brightcookie’s xAPI LRS lxHive. The difference to fully fledged LRS alternatives (LearningLocker) is that lxHive is machine-to-machine focused and thus it’s very hands-on and barebone. No UI, no reports and only a few dependencies, fast and lightweight. Oh yeah - and it’s written PHP and OS/server agnostic.
Here some unordered MongoDb helpers for admin, reports and backups. Use them inside Mongo shell or with RoboMongo
