Hi, I'd like to build a web application that is capable of displaying & editing topology diagram (e.g. a network diagram with applications too). Effectively to have a graphically web based means of allowing a user to add nodes & relationships to represent a topology such as the following http://performancepointinsider.com/files/planning/.... So the model basically consists of nodes and relationships. Any ideas/advice on how best to do this, e.g.: Q1. Any open-source project that does something similar? Q2. Best way of handling the graphical aspect of the application? (e.g. prototype, extjs, etc?) Thanks

When I started teaching myself Prototype and Scriptaculous I wanted to write a Visio-type of program. The idea was to be able to add draggable boxes to the workarea and to be able to connect lines between them and to be able to add text and attibutes to the boxes. I never finished it, but you're welcome to take a look at/steal the code. It kind of works. The hardest part was the automatic line routing. http://jameslab.moveable.com/ajaxio - James.

thanks James, will do. I guess you didn't find an existing open source project that had already implemented such an app or library? Greg

PS. Does Prototype and Scriptaculous not cater for drawing shapes? Is this why you had to use Water Zorn's SVG library then?
