STEP 5: ENRICH THE REPORT WITH MORE AND MORE MATERIAL!
The participative nature of PoliCrowd platform allows users to collaborate in the characterization of the Points Of Interest (POIs).
The system distinguishes users between registered and not registered ones. Users who have not registered to the application have just the possibility to access the contents related to the POIs (i.e. comments, images, videos and audios), that have been previously uploaded by registered users. On the contrary, registered users (i.e. users possessing credentials for the login) have also additional rights. First, they can add comments and upload new multimedia contents (i.e. images, audio and video files) related to whatever POI, thus collaboratively contributing to their characterization. If the registered user is also the owner of a POI (i.e. the person who created that POI through the Android ODK Collect application), he/she has editing privileges on all the contents concerning that POI, i.e. both the details which have been previously inserted on the field and the POI information added by other registered users.
