Microsoft Fabric IQ launches Ontology (public preview)
Microsoft has introduced Fabric IQ — a workload in Microsoft Fabric — that includes an Ontology feature (currently in public preview) to give enterprise data a shared business meaning. Ontology describes business concepts (customers, orders) and relationships independently of underlying schemas, and works with Power BI semantic models and Microsoft OneLake. The layer aims to provide consistent metric definitions for analysts and AI agents, enable NL2Ontology natural-language queries, and improve traceability, reuse and speed when deploying agents. The article contrasts Microsoft's platform-specific approach with Databricks' open-source Unity Catalog Business Semantics and Snowflake's Semantic Views, and outlines technical and governance prerequisites (data in OneLake, managed tables, unique entity keys) and trade-offs around vendor lock-in.
A major platform vendor (Microsoft) released a technical feature (Ontology in Fabric IQ) in public preview that affects enterprise data semantics and AI agent behavior; comparable moves from Databricks and Snowflake increase industry impact.

Key Takeaways & Evidence Grounding
- Microsoft's Fabric IQ includes a feature called Ontology and is currently in public preview.
- Ontology defines business concepts and relationships independent of underlying table schemas and can be generated from existing Power BI semantic models.
- Databricks made Unity Catalog Business Semantics generally available and open-sourced its core implementation in Apache Spark.
- Snowflake released Semantic Views aimed at similar purposes of standardising business meaning and metric definitions.
- Ontology in Fabric binds only to data stored in Microsoft OneLake and requires managed tables and defined entity keys before binding.

FabCon 2026: Take on Microsoft Fabric IQ Ontology
A conference report from FabCon Atlanta 2026 summarizes the author's observations about Microsoft Fabric IQ and its Ontology capability. Fabric IQ is described as a workload that organizes data in OneLake using business language, and the workload includes semantic models and Data Agents; Ontology is a component of that. The author notes strong interest at the conference but limited practical understanding and recommends a cautious, wait‑and‑see approach for production use because Fabric IQ is still in preview. The piece argues semantic models plus Data Agents already address many AI use cases today, and that Ontology will be most valuable for graph-like multi-hop relationship queries and unifying real-time and historical data into single business entities. The author advises organizations to mature data platforms before adopting Ontology broadly.
Microsoft Fabric exposes MCP architecture for data agents
Microsoft Fabric has exposed its MCP-based architecture, shipping two MCP entry points that let AI agents interact directly and securely with Fabric data services. Fabric Local MCP (an open-source server) is Generally Available and runs on developers' machines, enabling agents to read live API specs, perform local-to-cloud operations, and integrate with CI/CD via a VS Code extension. Fabric Remote MCP is in Preview as a cloud-hosted entry point for autonomous agents (e.g., in Copilot Studio). OneLake MCP is also Generally Available, allowing agents to traverse OneLake hierarchies and inspect schemas and Delta Lake files. The implementation relies on the MCP (Model Context Protocol), adopted across multiple vendors, and enforces existing Fabric RBAC, audit trails and authentication. The move signals a bet on MCP as a standard connector for agentic enterprise integrations.
Enterprise Context as the Next AI Platform Lock‑In
The article analyzes Microsoft’s Microsoft IQ announcement at Microsoft Build 2026 and argues enterprise AI lock‑in is shifting from models to context layers that encode organizational memory. Microsoft IQ is presented as a unified context layer (Work IQ, Fabric IQ, Foundry IQ, Web IQ) that grounds agents in Microsoft 365 signals, permissions and governance. Work IQ APIs are scheduled for general availability on 2026-06-16 and API usage is indicated to be billed via Copilot Credits. The author notes major cloud and developer platforms (AWS, GitHub, Docker) are converging on governed agent runtimes with tooling for permissions, logs and sandboxing, and warns teams to treat context ownership, observability, cost and portability as platform engineering concerns.
