This work package focuses on the improvement of sensor and sensor related standards i.e. the OGC SWE standards. The main topics for improvements that were identified are sensor discovery, the sensor eventing architecture and the manual data input by human observers.

The main achievements of the work-package Sensor Networks Architecture are:

• The development and specification of a framework for sensor discovery. It consists of two service specifications, namely the Sensor Instance registry (SIR) which allows harvesting SWE service and provides an interface for search and discovery requests and the Sensor Observable Registry (SOR) which provides means for a web based semantic match making of observed properties. In addition a minimum metadata set for SensorML was defined to support the harvesting process. A mapping of this SensorML profile to the ebRIM encoding allows to include the harvested sensor metadata into OGC Catalogues (CS-W) and to access it with common discovery clients.
• A web form for the input of human made observations which hides the complexity of the SWE services and data encoding specifications. It allows non-experts to enter sensor data and submit it into SWE services such as the Sensor Observation Service (SOS).
• An integrated demonstrator showing the Sensor Alert Service (SAS) and Sensor Event Service (SES) in action combined with techniques developed in other WPs
