RDF file statistics

[apologies if this ends up as a double post.  I sent out this message a

so resending]

Hi there,

During the course of my PhD work I've been working on a tool to produce
stats about RDF files that I thought you guys might find interesting/useful.
 You can see some example datasets at: http://www.zaltys.net/examineRDF/ .
It's mostly designed for RDF store creators/maintainers, to validate (or
challenge :-) ) their assumptions about the structure and characteristics of
common RDF datasets, and identify unusual edge cases that may result in
abnormal behaviour.  Hopefully it will also be useful for identifying flaws
in the realism of automatic data generators, and allow people to better tune
adaptive data structures in their stores.

I'm aware that the clarity and explanation of the graphs could be rather
better, but I find myself struggling to find the right words at the moment.
 If you have any suggestions for improving this (or the output as a whole)
I'd really appreciate it!

Thanks,
