Part-of relations are central to anatomy. However, the definition,
formalisation and use of part-of in anatomy ontologies is problematic.
This paper surveys existing formal approaches, as well as the use of part-
of in the Open Biological Ontologies (OBO) anatomies of model species.
Based on this analysis, we propose a minimal ontology for anatomy which
is expressed in the Semantic Web languages RDFS and OWL-Full. The
paper concludes with a description of the context of this work in captur-
ing cross-species tissue homologies and analogies.
The increasing number of anatomies being defined, published and linked
to gene expression data provides new opportunities to explore tissue ho-
