Hi Reto, While we look into your issues, assuming you are using the very latest 5.0.3 release of Virtuoso, you can also do the following:
1. Upload RDF to the Quad Store by simply executing a SPARQL Query against an RDF information resource URI (Graph Name with be the resource URI) 2. Install the ODS-Framework and ODS-Briefcase Application which allows you to simply upload to the Quad Store via it's UI Additionally, the RDFSink feature is only for automating the process of populating the Quad Store from a WebDAV resource upload.
