 Data recorded by Sensing Tasks (STs), processed by Privacy Mechanisms (PMs) and sent to the EasyHarvestServer (EHS) by the EasyHarvestClients (EHCs) should follow a specific structure shown in the table below to achieve proper communication and function of the framework entities. This way, we patronize the data collected without limiting application capabilities and Sensing Task developer freedom. For instance, the values field from an application that monitors location would typically contain [0] longitude, [1] latitude and optionally [2] altitude and [3] speed.
