Example: WebFlow at NPAC
We illustrate here a simple but fully operational Web based ComponentWare model - WebFlow at NPAC
Components are given by Java modules, connected by dataflow channels using visual programming tools
Object Bus is given by a mesh of Java Web Servers, hosting WebFlow modules via specialized servlets
Framework is provided by the visual graph editor applet plus domain specific module libraries (HPCC, imaging, collaboratory are examples shown in next 3 foils)
Ensembles are given by user-developed modules, following the WebFlow API
