PROTON Mapping to UMBEL
The mapping between the PROTON Ontology and the UMBEL Reference Concepts Structure was generated by hand.
For each PROTON class, we found an equivalent concept, or a parent concept, in the UMBEL Reference Concepts Structure. Once we found a potential candidate, we had to make sure that the underlying structure of the class, within the PROTON architecture, was consistent with the UMBEL ontology structure.
If a match was found, we generated a
rdf:subClassof relationship between the PROTON class and the UMBEL reference concept. At the end of the mapping, all PROTON classes were made
rdfs:subClassOf of one UMBEL reference concept.
Once the mapping was finished, we made sure that the linkage was consistent and satisfiable by using the noted ontology testing methods.
