+              v25
 Recognition can happen explicitly, i.e. in response to observation requests. In these cases, the time and location as determined by the request are used to establish a presence. Explicit recognition events may lead to establishment of explicit absence (=this one not here now).
 Locations in presence records represent geospatial features, which can basically be of any valid feature class (points, polygons, lines etc.). Where references to locations are used in communications, they must be universally unique and resolvable; otherwise the referred geospatial information have to be enclosed in the communication.

 In contrast to that, ''time'' in this regard means one exact time point, to be stored as coordinated universal time (UTC, Gregorian date including century) with a minimum precision of one second. Relative times must not be used.
