Systems, methods, and computer-readable media are disclosed for utilizing semantic technologies to provide an integrated information source that is accessible and capable of being manipulated via an augmented-reality (AR) device. The AR device provides a user interface via which a user provides gesture-based or voice-based input to access and manipulate data in disparate and independent data sources using a semantic information model. User manipulations to the user interface provided by the AR device are reflected in the underlying semantic information model and the underlying data values associated with entities represented in the semantic information model. The AR device also provides a user interface for performing virtual testing of replacement assets with respect to a physical machine in a real-world environment. In addition, the AR device enables the user to first manipulate a virtual machine and then have a real machine mimic the simulated manipulation/movements.
