Hi Alejandro, What Markus proposes can work if what you want is to model different observations of different properties (which seems to be the case since they come from different sensing procedures). However, you probably also should relate both observations (this is related to the "grouped in some appropriate structure" text in the report). To this end you would need to add further contextual information (e.g., time, ___location). Following the example below, you could do something such as adding: :o1 ssn:observationSamplingTime "2014-04-10T18:00:00"^^xsd:dateTime . :o2 ssn:observationSamplingTime "2014-04-10T18:00:00"^^xsd:dateTime .
