Upper level ontology for CCO. The ULO provides a hierarchical scaffold, including generic terms (for example, cell cycle gene), which serve as 'hooks' for hanging the integrated resources. The dashed rectangles represent the type of data residing below the parental nodes: the node called 'Data from GO' under the term 'cellular component' shows the placeholder where the cellular components from GO are placed (for example, nucleus), the node 'Data from UniProt' under the term 'protein' shows the placeholder where protein data from UniProt resides (for example, p53), and so forth.
