Finally all testing and bugfixing is finished. OpenLink has done an outstanding job with this new release of Virtuoso. Again my thanks go out to the Virtuoso development team and Patrick van Kleef who was my contact to smooth out the issues which prevented us to use Virtuoso 6 with Nepomuk.

So now is the time for distributions to package Virtuoso 6.1.0 and for you to update it on your own. But wait, there is one little detail: the database format changed significantly between Virtuoso 5 and 6. That is why I wrote a little conversion tool called Virtuosoconverter which takes care of this problem (Caution: the build system will download the Virtuoso 5.0.12 sources which are roughly 60MB). Usage is simple:

Shut down Nepomuk Install Virtuoso 6.1.0 Run the Converter Restart Nepomuk

Virtuoso 6 offers a wide range of features which are yet to be exposed through Nepomuk. The fun is only just starting!

Hints for Distributors:

You might want to run the converter in auto mode before starting Nepomuk.

If you do not like the build system downloading the Virtuoso 5 sources simply put them in the source tree. The build system will pick them up and use them instead of downloading.

Updates:

If you have old Virtuoso V5 data and do not run the converter after updating to Virtuoso V6 Nepomuk will not start.

The converter is the only way to convert the data to the new database format (except if you run some sql commands on the server manually)
