I've been trying for literally weeks to get our ontology and mapping setup. Most of our data is from a custom source but some of it is from a commercial AV vendor. I've deleted mapping categories that I'm not sure how to make come back and despite manipulating the mappings and ontology on every level, nothing seems to change my entity graph.
What i really want is for somebody to sit with me on a zoom call and help me prototype an ontology and mapping configuration because I know what I want to do but despite weeks of watching videos and reading documentation I still have no clue how to accomplish it.
