This is kind of off topic in a sense, but what the heck...

I have now tried to import a database with the website of a reasonably
large customer containing ~300.000 objects. It worked very well. I am
happy with the size of the database (1Gb), and after having indexed some
XML XPath's (hence making the RDF database contain ~3.000.000
statements) we can now do some SerQL queries on the data that we have
not been able to do before in a convenient way. I'm very very happy with
the results so far.

It looks like this is going to be very useful in a real-world
application in a way that I have seen no other data management
technology do before :-)
