Abstract: A cloud-native content management system includes a content file system for storing digital content to be accessed via the Internet using a compute device. The system includes an authentication and authorization service that applies rules of granular access controls among a group of specified individuals. Using a token-based, temporary access process, authorized individuals are provided direct access to selected digital content in order to bypass time-restriction limitations that traditionally prevent the streaming of large data files. The system is additionally designed to support the interactive, online editing of stored software models by authorized users. As part of the modeling process, model change requests are submitted by authorized individuals using user-intuitive, domain-specific language. Thereafter, the software model is temporarily locked while the change request is validated for correctness and compatibility.
