| WebWork is an open, world-wide distributed computing environment based on computationally extended Web Technologies |
| The backend computation and information infrastructure is provided by the World-Wide Virtual Machine -- a mesh of computationally extended Web Servers (called Compute Servers) |
| These servers manage (via CGI mechanisms) a collection of standardized computational units called WebWork Modules. |
| Geographically distributed and Web-published WebWork modules interact by HTTP/MIME based message/object passing and form distributed computing surfaces called Compute-Webs |
| The front-end user/client interfaces are provided by evolving Web browsers with increasing support for two-way interactivity (e.g. Java, VRML) that facilitates client side control and authoring. |
| A natural user-level metaphor -- WebFlow -- is supported in terms of visual interactive compute-web authoring tools. |
