(A) The global development concept has been combined with the anatomical concepts from the anatomical dictionary. This figure only illustrates the first 21 lines of the complete vocabulary. The complete vocabulary would include all of the anatomical terms in Figure 3. In the combinatorial terms presented here, the concept of development taken from the process ontology is shown in boldface. This ontology provides an “anatomical” view of heart development. (B) The developmental process ontology has been combined with the anatomical concept of the heart. In this case a simple rule of adding the phrase “during heart development” was added to the developmental process ontology. This new ontology gives a low-resolution “embryological” picture of heart development. This figure only illustrates the first 29 lines of the vocabulary. The complete vocabulary would include all of the terms shown in Figure 4.
