After the successful completion of the Spoken Dutch Corpus (1998 -- 2003) the time is ripe to take some time to sit back and reflect on our achievements and the procedures underlying them in order to learn from our experiences. In this paper we will in particular pay attention to issues affecting the levels of linguistic annotation, but some more general issues deserve to be treated as well (bug reporting, consistency). We will try to come up with solutions, but sometimes we want to invite further discussion from other researchers.
