Abstract
We describe the axiomatic content of a biology knowledge base that poses both theoretical and empirical challenges for OWL reasoning. The knowledge base is organized hierarchically as a set of classes with necessary and sufficient properties. The relations have domain and range restrictions, are organized into a hierarchy, can have cardinality constraints and composition axioms stated for them. The necessary and sufficient properties of classes induce general graphs for which there are no known decidable reasoners. The OWL version of the knowledge base presented in this paper is an approximation of the original knowledge base. The knowledge content is practically motivated by an education application and has been extensively tested for quality.
