Abstract: Using stream-based change flow models to propagate source code file changes within a software configuration management system can begin with the detection of the addition of a source code file, either a new file or new version, to a software configuration management system by a change flow manager. The source code file can then be related to a component based upon the hierarchical placement of the source code file within the filesystem. Stream-based change flow models that contain the component can be identified. Change flow relationships within a stream-based change flow model can define the propagation of changes between streams (an aggregate of components) and/or components. Authorization from a human agent can be requested to initiate propagation of the source code file. Upon receipt of an affirmative response, the source code file can be automatically copied to the container objects that correspond to the identified recipients for changes.
