What is a Network Node? “A simple environmental information Web service that initiates requests for information, processes authorized queries, and sends/receives the requested information in a standard format. ” – – – Is a Server accessible on the Web Complies with the protocols to ensure secure exchanges Sends and receives standards-based messages Returns requested information as XML Each partner has only one Node 9

Node Client Applications – Simplify access to services on full Network Nodes Ø Cannot listen (and respond) to requests from other nodes Human-to-Machine interaction – Easy to install and use – Available in. NET and JAVA versions – Node Client Software Developer Kit (SDK) simplifies integrating Node client functions (web service calls) with just a few lines of script – 10
