Ontology is only as good as its assumptions and premises. It is evidence, not ontology that proves a proposition.
One way to look at is.... Ontology is the study of reality. Ontology is supported by objectivism, thus has ability to be proven. For example, organizations in which we carry out data collections for our research exists in reality and can thus be proven.
Another to look at it is... Ontology is not itself reality; it is theory of, or words about, reality.
More....Ontology is the study of being, it tries to understand the reality.
