I not sure I can be of help to you. I am a wanna be ontoligist. I have no practial experience only playing around with semantics for the 15+years gaining a basic understanding along with KGs. I am willing to learn as I realize building my own ontologies does not provide me with skills that would be useful to others. All the organizations (DOD) I worked for were not interested in semantic technology which is where I would have gained relevant experience. However I am retired and do not have an environment that would give me that experience.
