thanks for all the hints! I like the schemaweb, because it uses a  
crawler, but also like the other more "publisher"-oriented tools. I  
was looking for a more user-oriented tool.

Basically we have to options to access a LOD dataset: browsing (thats  
what typically people do at the moment) or by SPARQL (what I'm doing).  
If you go for SPARQL, you usually don't have a glue how the graph  
behind looks like. That's why I would like to have some vocab browser  
which helps me to get some more glue which properties I can use in my  

What I'm looking for is some more graphical or intuitive view on  
vocabularies around probably in some clusterd manner. On the one hand  
I would like to have a web-scale clustered view, on the other hand a  
view just generated from some SPARQL endpoint.

Some vocabs are not interlinked (so different cluster here), others  
heavily - either by vocab concepts explicitly like RDFS domain/range  
pointing to external classes, sub-classing, equivalent property/class,  
etc. or implicitly by poeple using the different vocabs. By implicitly  
I mean, vocabs where the T-Box has no assertions but people typically  
use it that way, especially in the RDF-only way (without RDFS and  
explicit classes).
