An example of an annotation triplet in the metadata of a model resource. Example illustrating the structure of a typical model resource A (in this case, an SBML model) in which element B is shown to bear (i) a human-readable text label G, as well as (ii) machine-readable metadata C. The annotation triplet is composed of a DMR element URI (D), a relation (F), and an ontology URI (E). In the above example, the annotation in the metadata conveys the meaning that the model's reaction with the Unique Resource Identifier (URI) 230655 (D) occurs in (F) the anatomical location identified by URI FMA_9477 (E). The latter URI represents the sinoatrial node term in the Foundational Model of Anatomy [29].
