In this paper we discuss a spatiotemporal layer of annotation to be added to an existing (syntactic) treebank. Although our system, called MiniSTEx, was developed for Dutch, it will also work for other EU-languages. This may, however, ask for some adaptations to the database which is the centre of our system. Next to adaptations for other languages, we may need adaptations for specific situations, even when only one language is covered. 1
