Let’s be honest: many of us are trying to run 2025 AI ambitions on 2010 data habits. Nightly batches, opaque KPIs and committee-driven governance don’t survive contact with agents, RAG and copilots.
The more I work with transformation leads, the more I see two patterns emerge again and again:
1 Real-time velocity and semantically-rich data are no longer optional.
2 Federated production + centralized semantics is the only model that really scales.
This forces a redesign of the Data Operating Model (DOM):
- Instead of “we have a data lake, we’re fine”, we need an event driven + streaming + semantics fabric.
- Events, not just ETL.
- A semantic layer where metrics, dimensions and policies live once and are reused everywhere.
- RAG and agents consuming governed semantics and live APIs, not random tables.
And the “data mesh vs central model” wars? They’re a distraction. Data mesh delivers measurable outcomes.
What actually works is:
- Federated production: domains own their data/real-time data products.
- Centralized semantics: a small central team owns the shared language of the business, metrics and the policies around it.
- Governance becomes computational: contracts, lineage and rules in code, not PDFs nobody reads.
- Semantic layers are becoming the governance firewall, resolving data chaos. The semantic layer emerges as the critical “universal translator” between raw data and analytical/AI systems.
- Data/AI/Analytics Architecture Convergence on Six Pillars: (1) Ingest/Stream, (2) Prepare/Transform, (3) Define/Model (semantic layer), (4) Store/Persist, (5) Integrate/Orchestrate, (6) Deliver/Share. The “Define/Model” stage—semantic layers + metadata management—is the control point for AI governance.
If I had to prioritise the next 12–18 months in a DOM, I’d push for three moves:
– Stand up 3–5 domain teams with clear P&L-linked data products.
– Create a semantic council with the authority to say “no” to broken KPIs and unsafe policies.
– Fund based on outcomes: latency, reliability, AI use-case adoption and reuse of shared semantics.
The hard question is “where do we start federating ownership without losing a single source of truth on meaning and controls”?
I’d love to learn from others here:
Where is your DOM actually stuck today — events, semantics, domain ownership, or governance?
