<span style='font-family:Verdana'><span style='font-size:12px'>I've been running KDE 4.6.3_0 on Mac OS X 10.5.8.<br /> 
And Nepomuk has been working nicely for me, I have installed KDE just so I'll have access to Nepomuk on Mac OS X.<br /> 
I've upgraded some other (unrelated to kde) package and failed to notice that it has upgraded qt4-mac and as it seems resolved the dependencies and upgraded to KDE 4.7.1_0, which doesn't even compile on OS X, but that's a diffrent topic.<br /> 
<br /> 
somewhere in the process I think I have lost some of my RDF data.<br /> 
not sure where it went and I'd like to try and rescue it. I think I discovered the missing data only once I've rebooted after (..some days) of the failed upgrade.<br /> 
<br /> 
having looked a little on the file-system I've notice that I have three copies of soprano-virtuoso.db.<br /> 
<br /> 
What I really would like is a way to dump those soprano-virtuoso.db and see if I can locate the missing data there. I'm assuming the reason I have these three is because of the mistaken upgrade<br /> 
and subsequent downgrade. and I hope that some data survived there.<br /> 
<br /> 
What's the best way to dump the data (or poke around in the database)?<br /> 
<br /> 
Can I just run a second soprano copy somehow and point it to the twin database file, or mabye export the data somehow using virtuoso tools?<br /> 
<br /> 
=== here is some data on various copies of soprano-virtuoso.db on my system: ===<br />
