The Open Sensor Web Architecture (OSWA) proposed
by NICTA, at University of Melbourne extends the
Sensor Web Enablement (SWE) and further
integrates the Sensor Web and Grid Computing as
well as providing middleware support of Sensor
Web. The Sensor Collection Registry Services
have been implemented and deployed on Tomcat and
Apache AXIS. Clients can enquiry the Sensor
Registry Service about available Collection
Service according to their requirements and send
data query via SOAP messages to obtain the
observation data conformed to the XML schema
defined by Observation Measurement. Different
type of connectors have been designed to fit into
different kind of resources including sensor
networks running on top of TinyOS, TinyDB
application and remote observation data archives.
