A general introduction to design patterns is presented, and the use of patterns in the context of emergency management. Furthermore, it describes the use of patterns in the context of the BRIDGE project. Scope and sources of patterns are described, as well as the implementation of the library, together with its features and functionality. A literature review is also provided, demonstrating a number of design principles and user interfaces in the field of emergency management.
