ACGT Master Ontology

The ACGT Master Ontology, which has been developed within the FP6-IST project "Advancing Clinico-Genomic Trials", has the aim to represent the domain of cancer research and management in a computationally tractable manner. The ACGT MO is built being maintained, using the Protégé-OWL free open-source ontology editor, Version 4. It is written in OWL-DL and presented as an .owl file. The ACGT MO is re-using Basic Formal Ontology (BFO) as upper level and the OBO Relation Ontology.
