Als onderdeel van de 2e plenaire bijeenkomst van de Geonovum Pilot Making Sense for Society namens de IoT Standaardisatie werkgroep een presentatie gehouden over het belang van standaardisatie en de beschikbaarheid en mogelijkheden van de OGC Sensor Web Enablement (SWE) standaardenset.

1. Making Sense for Society
Werkgroep Standaarden
Bijeenkomst 4 juni 2014 NSO Den Haag

2. IoT Domains (Beecham)

3. Need for Standarization
 Internet of Things is a holistic concept (cross
domain / cross platforms)
 Currently many vendor specific hardware and
software protocols used in IoT solutions
 Standardization (technical & semantic) over
different domains, and on all levels of the OSI
stack, is needed to make machines talk
(“1001001110”) to each other (Machine2Machine
or “M2M” communication)
 Standardization efforts by W3C (SSN), OGC
(SWE) and other mayor standardization
organizations

4. Machine Communication (the OSI model)
 Focus in Geonovum Pilot on the top level of OSI Stack

5. OSI model Main Protocols

7. What is a Smart Thing (IoT-A)

8. Sense – Analyse – Act(uate)

9. Standardization in Event Processing

10. OGC and Standardization
 SWE standaarden overzicht
http://www.opengeospatial.org/ogc/markets-technologies/swe
– SOS Sensor Observation Service (Sensing)
– SPS Sensor Planning Service (Actuating)
– SES Sensor Event Service (Event Stream Processing)
– SIR/SOR Sensor Catalogue (extension on CSW)
– SW for IoT (new light weight version of SWE for IoT devices)
– PUCK (plug and play devices)
– …(see A0 overview)
 OWS Demonstrations (usage of SWE standards)

11. OGC SWE Standards

12. OGC Sensor Web for IoT
 Workgroup http://www.opengeospatial.org/projects/groups/sweiotswg
 The initial scope of the SWIOT SWG seeks to make observations captured
by IoT devices easily available to applications and users through data
aggregation portals (e.g. data broker platforms like Xively, Thingworx,
Thingspeak, Se)

13. OGC Puck Protocol
Figure 1 illustrates how PUCK complements other OGC SWE standard
components. SWE services must sometimes interact with an actual
physical sensor in order to carry out client requests; e.g. the Sensor
Planning Service Submit operation ultimately requires that data
acquisition be triggered from a physical sensor. Many of today's
sensors are not themselves network-capable; instead they are
connected to the network through a sensor host machine's serial
port. Moreover most sensors themselves do not implement a
standard protocol; instead the SWE service must access the device
through a sensor driver, which runs on the sensor host and translates
the service request to the appropriate sensor protocol command. The
driver may also transform the sensor's response to a standard format,
e.g. it may transform the sensor's "raw" data to an OGC Observation
and Measurement object. Moreover, the OGC services also need
access to the sensor's SensorML document, which may also reside on
the sensor host. These critical sensor specific components - sensor
driver and SensorML document - can be stored in the sensor itself and
automatically retrieved and installed with PUCK protocol by a
component on
the host (not shown) when the sensor is physically plugged in.

14. IoT (real-time) Data Broker Platforms
 Real-time data broker for networked objects and environments
 Voorbeeld https://xively.com (aka Pachube)
 Collects and distributes data streams of sensors registered at the platform
 Can also alert, notify (actuate)

15. Goals Standardization Workgroup
 Short term
– Create overview of relevant IoT Standards in Netherlands
(A0 Overview and WIKI pages)
– Promote use of OGC SWE standards in the Making Sense 4
Society case studies
– Register Pilot services in a OGC Sensor Catalogue
(SIR/SOR)
 Mid term
– Promote / Use of OGC standards in Governmental IoT
projects (e.g. SOS)
– Extent Nationaal Georegister with a Sensor Catalog (based
on SWE SIR/SOR standards)
– Dissemination of sensor data through PDOK using SWE
Standards
– Role of PDOK as a IoT data broker platform for
Governmental use

16. Pilot Results of the workgroup
 Results of the workgroup will be published on
the Making Sense for Society - Living Lab for the
Internet website http://www.senseforsociety.nl
under the topic “Standards”
 A0 Overview
 WIKI pages

17. A0 Overview of use of standards in the Pilot
(first draft)
