The neat thing about this would be that you could generate a new graph snapshot for every month since the first date in the system and watch as new sub nodes and clusters spring up and little tendrels (sp?) creep out to each other. I'm also wondering if I should make it so that you have to log in and can only add a link between your entity (possibly making it so that non people entities are created by someone who becomes responsible for it) and someone else who is emailed when a link is added to to them. > This gets into the whole vast topic of trust and reputation metrics.

I did think about having something like that but just figured that was too complicated, would put people off adding new links and was basically unnecessary, for my purposes anyway. I just want to see the nebulous links that there are out there and see if there are any patterns. The problem with the patterns, as far as I can tell is that their emergence is subjective to the algorithm that graph drawing program uses. Graphviz seems to favour trying to stick everything in a flat line and then looping everything round the outside which isn't quite what I had in mind. I kind of want clustering. > http://paulm.com/friends/ecademy/ was a frenzied hack mapping a (mostly) > London business network a while back.

I actually did a prototype of what I was trying to do about 5 or 6 years ago but it crashed a commercial graphing program even then. I've been meaning to finish the code off for ages. I'm going to read through your list o' resources and I'd love to talk about this, I'm happy yo take it off list if people think it might get a bit dolphin noisey.

This is kind of what sparked the conversation last night. This and FOAF, I think, are trying to solve similarish problems but they're not *that* overlapping - FOAF is kind of a resource indicator and trust network thingy wheras what I'm trying to do is graphically map the networks and clusters that people have built up over the years - nothing more, nothing less. A FOAF export thing would probably be a better idea than a FOAF import. On Tue, Sep 24, 2002 at 07:53:29AM +0100, Roger Burton West said: > I think you should probably have both.

What, you mean, kind of like the 'worked' and 'lived' link types and the ability to add new link types? :) Simon
