5.4.3 SOS 2.0 Transactional Interface
For inserting the gathered data into the SOS 2.0 for Social Media the transactional interface of the SOS 2.0 interface standard was used. This way the implementation of
harvesting and the storage is connected via interoperable and well-established methods. This section provides a brief overview on the required interface interactions.
5.4.3.1 InsertSensor
Prior to the insertion of actual observations knowledge of the
procedure
to the SOS service needs to be provided. The user who posted the social media entry has been
mapped to the procedure in the Social Media model see section 5.3.1. The following request illustrates an exemplary
InsertSensor
request for providing these metadata.
