The Data Analytics and Visualization Environment (DAVE) is a specification and reference model for prototyping learning-domain specific analytics and data visualizations.

With the goal of providing a specified and interoperable way to analyze, interpret, and visualize micro-level behavior-driven learning, DAVE offers a framework for analysis and visualization which aligns with xAPI, xAPI Profiles, and the Total Learning Architecture being developed by the Advanced Distributed Learning Initiative (ADL).
