The basics
What is the difference between an ontology and a knowledge graph?
The ontology is the design: which entities exist, how they relate and what the rules are. The knowledge graph is that design filled with your real data, so a specific customer is linked to their actual contracts, invoices and service cases across systems.
What does agent-ready data mean?
Agent-ready data is data an AI agent can understand and act on safely: every term has one agreed definition, records are linked across systems, the rules and approval limits that apply are captured, and access is governed. Data Semantics builds this as a semantic layer, ontology, knowledge graph and context graph on the platform you already run.
Why it matters
Why do AI agents need an ontology?
Without one, an agent sees tables and columns and has to guess what they mean, how they connect and which rules apply, so nobody trusts it to act. With an ontology, it knows that the customer in the CRM and the debtor in the ERP are the same, which definition of overdue applies and what it is allowed to do.
How is a semantic layer different from data governance?
A semantic layer defines what your data means and how it is calculated. Data governance decides who owns it, how good it must be and who may use it. AI agents need both, and Data Semantics delivers them together or one at a time.
Platforms
Does it work with Microsoft Fabric and Copilot?
Yes. Data Semantics builds Power BI and Fabric semantic models, governs definitions and lineage with Purview, and gives Copilot and Copilot Studio agents the business context they need. The same approach works on Databricks and Snowflake.
What is Fabric IQ, and how does it relate to an ontology?
Fabric IQ is Microsoft Fabric’s semantic foundation for AI, including an ontology of business entities, relationships and rules that data agents and Copilot can use. Data Semantics builds Fabric IQ ontologies from your existing Power BI models, definitions and source systems, using its industry models as a starting point.
Can you build semantic models on Databricks or Snowflake?
Yes. On Databricks, Data Semantics builds governed metrics and business models in Unity Catalog for Genie and your agents; on Snowflake, semantic views for Cortex Analyst and Snowflake Intelligence. The same ontology can serve every platform you run.
Getting started
Do you have ready-made industry models?
Yes. Data Semantics starts from our library of industry models and mappings for real estate, banking, consumer goods, retail and hospitality, plus mappings for common ERP, CRM and core banking systems, then adapt it to your own business.
How long does it take to build an ontology?
Data Semantics starts with one domain, such as collections, leasing or sales, and model it in weeks, using AI agents and our industry library. Each further domain reuses what is already built, so it goes faster.
Who maintains the ontology after it is built?
Your data owners approve definitions, and our stewardship team, with AI flagging changes, watches source systems and proposes updates. We can run this for you as part of our managed data services.
