Figure 3
The reuse relationships of OBO Foundry candidate ontologies for March 2010 and September 2010. Each node represents an ontology. Please refer to http://www.obofoundry.org for the list of full ontology names corresponding to the acronyms that we use as labels in the graph. In each graph, an edge from a node representing an ontology O1 to a node representing an ontology O2 means that ontology O1 reuses at least one term from O2.
