In this talk, we’ll look at two use cases and a technology capability for xAPI Profiles that fully leverage the ability to define the vocabulary, patterns, sequences, and concepts that advance the business flow of semantic activity data through complex learning technology ecosystems. The first use case will touch on the application of xAPI Profiles to managing the brokerage of data by an AI Tutor engaged in the observation of learner behavior in a synthetic training environment. The second use case will contrast the design of a general-use xAPI Profile for video tracking with the design of a specific-use xAPI Profile for video tracking within the context of a medical training curriculum. In conclusion, we will explore the design of a novel software capability intended to make xAPI Profile authoring — especially for complex situations as described in our use cases — far more accessible for software developers and learning engineers.
