| 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. |
