This page describes the data format and restrictions of a Service Object descriptor
For spatial queries, a channel named location with type ‘geo_point‘ must be added to a stream It will represent the latitude and longitude as comma separated values: “34.5445 , 3.5533”
This example describes a sample Service Object that could be created for a Cell Phone with accelerometer, GPS and temperature sensors. It would provide raw data for the accelerometer (stream “accelerometer”) and geo-located data for the temperature (stream “located-temperature”). Later on, geo-located queries could be performed on the temperature data.
