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 |
