About the Experience API (xAPI) StandardxAPI is a data and interface standard that lets software applications capture and share (big) data on human performance, along with associated context information (i.e., “experience” data). Combined with learning analytics, xAPI promises to revolutionize the way education and training are conducted, managed, and measured. xAPI can be incorporated into nearly any (new or existing) learning technology, and it is agnostic about the type of learning content being delivered. xAPI is open-source and licensed under Apache License, Version 2.0.“xAPI” stands for Experience Application Programming Interface. The ‘x’ stands for experience, because xAPI enables detailed recording and transfer of “learning experience” data, whether those data come from an e-learning experience, a simulation-based training experience, a tablet-based educational experience, or even an operational (on-the-job) experience.Advanced Distributed Learning InitiativeADL_5649ca2a-5eab-11ec-a49c-55312283ea00Education and training are revolutionized_5649cbba-5eab-11ec-a49c-55312283ea00To enable software applications to capture and share data on human performance, along with associated context information_5649cd36-5eab-11ec-a49c-55312283ea00DataIn software, an Application Programming Interface (API) allows two or more applications to exchange data with (or “talk to”) one another.ExchangeSharingIn the context of education and training technologies, APIs can be used to share data about learners and learning activities.InteroperabilityHence, xAPI is a particular standard designed to enable the interoperable exchange of data about learners’ behaviors and performance.LearningBehaviorPerformanceStandardizationIn other words, it encodes someone’s performance using a standard format, and it follows standardized transportation rules to move those data to a data store or between applications.ActivitiesTrack and store data on activities_5649ce76-5eab-11ec-a49c-55312283ea00xAPI can be implemented in any digital environment, including mobile learning, simulations, virtual worlds, serious games, real-world activities, mobile and wearable devices, experiential learning, and more. It can be used to track and store data on any imaginable activity, such as:ReadingTrack and store data on reading an article or interacting with an eBook_5649cf5c-5eab-11ec-a49c-55312283ea001VideosTrack and store data on watching a training video, stopping and starting it_5649d10a-5eab-11ec-a49c-55312283ea002SimulationsTrack and store data on training progress data from a simulation_5649d236-5eab-11ec-a49c-55312283ea003Mobile AppsTrack and store data on performance in a mobile app_5649d2f4-5eab-11ec-a49c-55312283ea004ChattingTrack and store data on chatting with a mentor_5649d3e4-5eab-11ec-a49c-55312283ea005MentorsPhysiologyTrack and store data on physiological measures, such as heart-rate data_5649d4ca-5eab-11ec-a49c-55312283ea006E-Learning InteractionsTrack and store data on micro-interactions with e-learning content_5649d588-5eab-11ec-a49c-55312283ea007Team PerformanceTrack and store data on team performance in a multi-player serious game_5649d7e0-5eab-11ec-a49c-55312283ea008Quizzes & QuestionsTrack and store data on quiz scores and answer history by question_5649d8b2-5eab-11ec-a49c-55312283ea009Real-World PerformanceTrack and store data on real-world performance in an operational context_5649d984-5eab-11ec-a49c-55312283ea00102021-12-16https://adlnet.gov/projects/xapi/OwenAmburOwen.Ambur@verizon.net
