Abstract: A method includes receiving data characterizing digital content from a repository of digital content. The method also includes receiving data characterizing a right to use the digital content from a store configured to sell a right to use the digital content to a customer associated with a non-destructive testing device. The method further includes performing an inspection of machinery using the non-destructive testing device based on the received digital content and the received right to use the digital content. The inspection can be performed by one or more of executing, using, and displaying the digital content. Related systems, devices, and non-transitory computer-readable mediums are also described.
