I attended FabCon Atlanta 2026 .

I also created a few short videos that show the atmosphere of the venue, so feel free to check them out first.

In this article, based on what I saw and heard at FabCon, I would like to focus especially on Ontology within Fabric IQ and share how I think we should understand it at this point in time.

Fabric IQ is described as a workload that organizes data in OneLake using business language, enabling analytics and AI agents to use that data with consistent meaning.

The Fabric IQ workload includes semantic models and Data Agents, and Ontology is one part of it.

I think many people may currently understand “Fabric IQ” as almost the same thing as “Ontology.”

That is not completely wrong.…
