Architecting crowdsourcing systems: Challenges and solution ideas from the RESCUER project

The RESCUER system aims to create a smart and interoperable crowdsourcing solution to support emergency and crisis management, focusing on incidents in industrial areas and at large-scale events in Europe and Brazil. In this paper, we discuss about a set of key software architecture challenges for such a system considering different points of view (e.g. technical, functional, project settings, etc.). We believe our experiences will greatly benefit other organizations engaged in this kind initiatives of systems, since they might save valuable time and effort by discovering problems at a very early stage in the project.
