The Open Analytics Collaboration and Research Environment (OpenACRE) is a robust and scalable big data learning analytics platform implementing the latest specifications of Caliper, an emerging standard for the generation and collection of learning data both within and without learning management systems. OpenACRE is a plug-and-play infrastructure provisioning its users with competence, confidence, and regulation insights and includes built-in learning tools and analytics solutions. OpenACRE leverages big data technologies such as Apache Spark and Kafka to cope with the challenges of receiving and processing continuously flowing streams of data from a variety of disparate learning contexts. In addition, learning data will be controlled and forwarded over the wire through Software-Defined Networking (SDN) to federate diverse server resources, optimize bandwidth, and prioritize transport of high-priority learning events. Moreover, OpenACRE is also extensible to add in-house and public educational applications available on the Internet.
