The project is currently standing at a point where Tom had taken the SIAM node service and created a web service that can make RMI calls to translate between web service calls and RMI calls. The next step is to take that work and extend it so we can test interfaces that are designed to meet the requirements spelled out in the SENSORS workshop report. There are some related projects as well and we are trying to incorporate information from those into the prototype that we decide to build. One possible overlap is the SNMP project and their declaration of using an Enterprise Service Bus (ESB). This could be the mechanism that transports messages around, but how do we actually make useful conversations? The SOS specification tries to present standard interfaces that can put sensors on the web. It looks like we could setup a SIAM node to be a SOS data publisher and connect it up to a ActiveMQ. In theory the ESB would actually give us the slippage to put an interface up that is a web service interface that interacts with SOAP messages. In order to match the SOS specification, SOS messages could be translated to WS message calls. But in order to do that, the WS interface needs to support similar methods. So what do those methods need to look like?
