COEUS ontology model for the internal tree-based structure highlighting relationships amongst the various individual classes. A seed can have multiple entities, and each entity can be related to one or more concepts. Concepts aggregate unique items and are connected to resource and bridge information. The data import process uses resources’ properties (1) and custom methods can be defined to display data (2). Sample seed data for a “Diseasecard” seed is shown at each element, listing “UniProt” items belonging to a “Protein” entity.
