Foil 125 WebWork Architecture

From IBM Tutorial on Web Technology for HPCC IBM Poughkeepsie -- February 7 1996. by Geoffrey Fox * See also color IMAGE

WebWork is based on a three-layer architecture shown in figure 2, including: World_Wide Virtual Machine (WWVM) in the (bottom) layer 1, Middleware layer 2 of agents, wrappers, mediators etc., and high level programming environments (e.g. HPFCL) and user interfaces (e.g. WebFlow) in the (top) layer 3.
All base WebWork concepts can be implemented in terms of today's Web technologies (HTTP, MIME, CGI) and a prototype is under development at NPAC.
The overall design is open and ready to upgrade the existent (e.g. browsers or servers) and include new (e.g. agents or distributed object brokers) Internet/Web technologies
One starting point for the WebWork construction is provided by NPAC WebTools -- a CGI-extended Web server with enhanced content authoring and database navigation functionalities. WebTools Server is used as a prototype WebWork node server.
