What are these guys doing?
Why do we trying to build on prehistoric technologies?

I had attributes first, but the CSS for getting the information again out of
the attributes was far beyond what any user would be willing to write down.
Having nice CSS selectors was also the reason for the rather verbose XML.

I guess everybody will get what is meant with

foaf:person > fresnel:property > foaf:depict > fresnel:value

Please express "Display all person that know more than 30 other persons
using a special color" with a CSS selector ;-)

I'm not sure yet.

Would something like this fit into IsaViz?
