Ontology Design Patterns (ODPs) are well known and efficient modeling solutions for ontologies. This public catalog offers a collection of well documented and tested ODPs, including examples from the biological knowledge domain, implemented in OWL. ODPs are ready made modelling solutions for creating and maintaining ontologies; they help in creating rich and rigorous ontologies with less effort. This is a public catalog of ODPs focused on the biological knowledge domain. ODPs in this catalog have been collected elsewhere or created "in house" and they are open for discussion. ODPs can be applied in ontologies using OPPL (Ontology PreProcessor Language), the wizards provided by the CO-ODE project, or simply by hand.
