Operating System

Ubuntu and Debian (latest release), any other Linux distributions should be fine too. (If you have tried a setup on other Linux distributions or even other Operating systems, reports about special issues would be interesting for us too. Please report them at our mailing list: ontowiki-user@googlegroups.com.)
