Re: [Exist-open] A theoretic question: it makes sense mixing the exists and Neo4J models?

[Paolo Di P. <pdi...@di...>]

Thanks to Dmitriy and Dan,

You both have an opposite point of view, while Dan can see some 
advantages and Dmitriy say that's nothing you can't do with exists.
It's just when you go to a doctor for a consult: you always nedd an odd 
number of answers!

now I'd like to go one step forward, and I 'd like to integrate eXist 
with a tool for drawing OWL/RDF relationships.
In general I'd loke to draw any kind of relationships between any 
couple of objects on the web.

But the nice thing should be a tool able to do it live, with at least a 
little smartness to minimize the number of connection crossings ....

Any suggestion in this fiels?

Paolo
