I am not sure to have understood the question: I would advice the work of Jonathan Lowe "The four-category ontology: a metaphysical foundation for natural science". He exposes his own theory of ontology and of epistemology, on the one hand, and he compares his theory with alternative theories.
We can uderstand ontology as a traditional discipline that talks about "being", and on the other hand, epistemology talks about knowledge theories, i.e., the way we know the things.
i highly recommend to you some texts like "Ontology: hermeneutic of facticity" by M, Heidegger, and "Discourse on the method" by R. Descartes: th first one to understand what is ontology, and the secod one to comprehend about epistemology.
The erroneous division of philosophy into ontology and epistemology is based on the doubling of experience: the philosophy of the result and the philosophy of the process. In the first case, knowledge is detached from the subject and presents itself as an objective truth. In the second case, knowledge is reduced to the method.
Ontology deals with e.g. :"What are the meanings of being?"
while epistemology relates to the philosophy of knowledge, belief, truth, value, ,reliability and so on
For example, having a reliable faith that produces a meaning in life would be more valuable than having an unreliable one that produces nihilistic philosophy because the reliable one would more likely produce a will to survive in hard circumstances compared to the unreliable one. My understanding does not necessary be the correct one, but if you read our paper where one ventilator-bound woman took as a goal to paint and the other ventilator-bound to have the right to kill her self, you may apply an example of this:
In case you mean that I interpret ontology as something that can be interpreted then I suppose the concepts may have their "intercept". I do not know, this is only speculation.
In one way, we know ontology studies the being while epistemology the theory of knowledge that consists of the being. A simple example is this question if not being would not get answers and since its a good question as being then it gets answers but the way we understand it with our knowledge to form the right answer may be the epistemological proof of the being that gives it meaning in the form of this answer. Ontologies and epistemologies are created by us humans and they may be wrong like you may not agree with this answer as it may be wrong or right for some or not. Epistemologies and ontologies follow some sources of transcendent being that is God who created everything and due to our poor comprehension of it then we fail to grasp it. And because of that we realize that God is all powerful and strive our best to understand answers like this. We exist (ontology) and understand but variably and variability of understanding sources from our differences in accumulated knowledge (epistemology). This will help you get sparked to further thought about matters of ontology and epistemology. :)
Md. Shahadat Hossain Khan Ontology involves categorization of things (physical objects, abstract entities, qualities, properties, etc.). Thus, devising ontologies or ontological frameworks can be regarded as a step preceding research (i.e. the quest for knowledge, which is the concern of epistemology); for some kinds of research this can involve the structuring or restructuring of databases. I am not familiar with current issues in education, but I would assume children's math education would involve ontological issues, e.g. should primary school math proceed from basic set theory or not? (Cf. the controversies over the "New Math" in the 1960s.) Is the ontology of sets more conducive to mathematical learning and understanding? Those would be epistemological questions. (The issue of what kind of ontological framework to use also figures in the various methodologies for ethnomathematics in education.) Therefore I suggest:
Ontology in education -> the categories into which the subject matter is conceptualized (a prerequisite for teaching and learning)
Epistemology in education -> the methods of teaching that are most efficient, effective, etc. for implementation, instructional delivery, and student learning and understanding (this will include choices of ontology)
Barry Smith is a preeminent ontologist who has received millions of dollars in grants for a variety of ontological projects. If you can't find anything relevant to education on his websites, perhaps you could contact him directly with your question.
Ontology can be understood in example, in simple terms, also as existing things which exist for some reason or the other (like literature in any field) but the way we construct new literature with help of that existing literature is what constitutes epistemology in deeper sense because we use literature of a/some fields to add something new and so the new contribution reflects the epistemology (for example methods of how we came to such new contributions). It may be confusing now as that sounds like methodology but methodology has an epistemology and even ontology root and so dies literature its own and that shapes every individual in the way he/she thinks and acts. Knowingly or not, it is happening. Thats why i mentioned 'in simple terms'. Those are examples.
