The first goal to describe a little what would be call misperimenting with graphDB, RDF, and all fun stuff, without being to formal, and (I am very sorry for that) some misenglish everywhere.
And of course if it could help or inspire anyone for more useful tests it should be great (in did this a few month ago but have not time to pursue).
There are not so many graphDB implementations, it is quiet odd considering the hype of NoSql idea and current social graph applications.
