scope:

This standard defines two description languages for expressing augmented reality (AR) learning experiences. This document shows how to represent activities conducive to developing or upgrading knowledge, skills, abilities, and other characteristics in a standardized interchange format. The interchange format links the representation of learning activities with their environment and context in the actual (or simulated) workplace, classroom, or other environment in which an AR-enhanced training system may execute them. The specification aims to lower entry barriers for authoring of learning experiences that involve interaction with the real world, sensors, computer vision, and web applications.

Purpose

This standard for augmented reality learning experience models (ARLEMs) provides an overarching integrated conceptual model and the corresponding data model specifications for representing activities, learning context, and environment (aka "workplace"), while linking with other data model components needed for AR-enhanced learning activities.

The standard distinguishes slow-changing data for environment description from fast-changing data for step-by-step guidance. It defines the required data models and modeling languages and their bindings to Extensible Markup Language (XML; see XML 1.0) and JavaScript Object Notation (JSON; see ECMA-404).¹

The purpose of this standard is to support the discovery, retrieval, transfer, and execution of AR-enabled learning content, thereby facilitating the creation of repositories and online marketplaces.

Finally, the standard supports reuse and repurposing of existing (learning) content in "mixed" experiences that combine real-world guidance with traditional media such as instructional video material or existing web applications and widgets.
