Abstract. Intuitive ontology visualization is a key for their learning, exchange, as well as their usage in conceptual modeling. OWLGrEd is a visual tool for compact graphical UML-style rendering and editing of OWL 2.0 ontologies. Here we introduce into OWLGrEd visualization annotations that allow defining custom visual presentations of ontology entities on the basis of annotations attached to these entities. The introduced mechanism of attaching visual annotations to annotation properties used in the ontology, besides being convenient for attaching graphical shape to user-defined annotations, appears to be powerful enough to cover visualization of e.g. UML stereotypes and other UML constructs that do not have direct counterpart in the "logic " part of OWL.
