FIGURE 2.

AOP-DB Semantic Mapping using illustrating the predicates and objects of the nine core subject types in the AOP-DB RDF (in blue). Vertical columns show subjects, and the middle and right columns indicate predicates and objects, respectively. Where applicable, the type of entry is indicated (literal or IRI). Yellow objects with an asterisk (*) indicate the connection between their subjects and the subjects of other tables. The interaction with the AOP-Wiki RDF is highlighted at the Key Events and Adverse Outcome Pathways (in green). Forward slashes indicate the inclusion of multiple objects as part of the subject-predicate-object triple.
