 When we talk about ontology we can take it in two different ways, we can take it in the philosophical sense of an inquiry or a study into the nature of being, so thinking about what exists and then we can take it in the kind of anthropological sense as referring to kind of like a set of things that a particular group of people holds that exists, if that makes sense. So some people have said that when we talk about ontology in anthropology what we're really talking about is it's just another word for culture or worldview, but actually it's more than that. We're not just talking about beliefs but we're talking about kind of whole world-azonian shamanic society for example is going to contain a whole load of other kinds of entities, beings, different kinds of things to a kind of Western materialist ontology. So yeah that's what an ontology is, it's the sum of all the things that exists within a particular framework. Awesome. Fortian.
