When the market says “semantics” right now, it often means one of three things: mapping business terms to schema, standardizing metrics, and adding more context to how natural-language systems query data.
Those are real advances, and they matter, but they also make it easier to treat several different layers of the problem as if they had already been settled.
A semantic model can make a system easier to query, and a cleaner metric layer can make definitions more reusable, while the harder enterprise question remains open:
what exactly is the object the business is trying to preserve, where do its boundaries sit, and which system is actually allowed to define it over time?
