WP4 is dedicated to the enhancement of the Solutions Explorer, the web-tool developed in ROADMAP, adding more features, e.g., enabling to include the input on GPs from external actors after a suitable recognition of their role in DRM (e.g., volunteers; decision makers at strategic level; first responders; researchers, etc.). WP4 will take into account the criteria to recognize GPs elaborated in WP3, and a consequent check of the GPs inserted will be performed before their release to external users.
