Collaborative Modeling and Visualization of Software Systems Using Multidimensional UML

This paper introduces our approach to a real-time synchronous collaborative modeling of software systems using 3D UML in a way similar to shared Google Document online with the aim to reduce the complexity of UML models and to increase work efficiency. In our approach, we decided to visualize the system with 2D UML diagrams on interconnected layers containing components (in class diagrams) or use case scenarios of the system (in sequence or activity diagrams) in 3D space. The goal of our method is to improve user's awareness of other developers in a multi-user workspace, adjust redundant components and visualize the history of user's actions in the UML class diagrams.
