Yes, the testing by the community has exposed enough small and medium bugs in the datasets so that we are going to extract a new fixed 3.5.1. release next week.

I'm my opinion the bugs do not impair Robert's and Anja's great achievement of porting the extraction framework from PHP to Scala. If you rewrite more than 10.000 lines of code for something as complex as a multilingual Wikipedia extraction, I think it is normal that some minor bugs remain even after their tough testing.

So, if you have discovered additional bugs and want them fixed.

Please report them to the DBpedia bug tracker until Friday EOB.

Chris
