Semantics Without Silos: AI Finally Solves BI’s Oldest Problem

Business intelligence has always been good at telling you what happened. It's never been great at telling you what to do about it. In this episode, AtScale's CEO and co-founder Dave Mariani sits down with Donald Farmer, Principal of Treehive Strategy, to talk about why AI is finally closing that gap. You'll get Donald's take on: How AI will start to take over the exploratory, discovery side of analytics Why "revenue" means something different to marketing, sales, and finance , and why semantic layers need to model relationships between data, not just definitions How treating semantic models like code (Git, CI/CD, AI-generated YAML) lets business users build them without needing to be a "unicorn" What Apache Ossie tells us about the industry's shared need for semantic standardization Donald's advice for enterprises and software vendors trying to figure out their AI strategy right now Key topics in this episode: The future of BI: routine dashboards vs. AI-driven discovery Marcia Bates' model of "browsing" (orientation, glimpsing, examination, acquisition) and where BI always fell short Semantic layers as the foundation for AI trust and governance AI as translator, not just code generator, for building semantic models Vendor lock-in, Apache Ossie, and Apache Iceberg as pieces of an open, portfolio-based data stack Donald's "go carefully, but go" advice for AI adoption

30 Hours to 90 Seconds: Blue Yonder’s Semantic Layer for Trusted Enterprise AI

What happens when enterprise AI meets inconsistent metrics, fragmented dashboards, and conflicting business logic? In this episode of the Data-Driven Podcast, AtScale CTO and co-founder Dave Mariani sits down with Brad Lindsey and Jeremy Arendt from Blue Yonder to discuss how Blue Yonder transformed its analytics strategy from disconnected dashboards into a governed semantic layer foundation for AI and enterprise analytics. The conversation explores why semantic layers have become critical infrastructure for AI, how governed metrics enable trusted self-service analytics, and why enterprises must standardize business definitions before deploying AI agents at scale. Key topics include: Why Blue Yonder shifted from dashboard development to data infrastructure Building a universal semantic layer for AI, BI, Excel, and LLMs How semantic models eliminate inconsistent metrics across the business Why semantic governance matters for agentic AI The role of Model Context Protocol (MCP) and semantic context in enterprise AI Creating reusable governed business logic for analytics and AI How Blue Yonder reduced analysis work from 30 hours to 90 seconds using semantic models and AI Scaling trusted self-service analytics without losing governance The future of semantic layers as operational infrastructure for AI The discussion also highlights a major shift happening across enterprise data architecture: semantic layers are no longer just BI tooling. They are becoming the governed operational foundation for AI-powered decision making. Learn how Blue Yonder is preparing for a future where AI agents, dashboards, copilots, and analytics workflows all operate from the same trusted semantic foundation.

Semantic Layers, OSI & AI: Why Context Beats Data Access

What does enterprise AI actually need to succeed: more data access or better context? In this episode of the Data-Driven Podcast, AtScale CTO Dave Mariani sits down with Coginiti CTO Matthew Mullins to unpack one of the most important debates in modern data architecture: access vs. understanding. The conversation explores the rise of the semantic layer, the role of open semantics, and why initiatives like the Open Semantic Interchange (OSI) matter for the future of AI and analytics. Matthew shares his journey from cognitive science and formal semantics into enterprise data, and how those foundations are becoming critical again in the age of AI. Together, Dave and Matthew break down: Why inconsistent metrics (like “29 definitions of customer”) still plague enterprises The real purpose of OSI and whether it should be an interchange format or a modeling standard Why semantic layers are becoming core infrastructure for agentic AI and LLMs How the Model Context Protocol (MCP) fits into the stack, and what it doesn’t solve Why AI cannot replace human-defined business semantics The shift from dashboards to AI-driven, ad hoc business intelligence The key takeaway: LLMs don’t understand your data; they understand language about your data. Without a semantic layer to provide governed definitions, relationships, and context, AI systems will produce inconsistent or unreliable results. If you're building AI-powered analytics, designing data platforms, or evaluating open standards like OSI, this conversation outlines where the industry is heading.

AI Needs Context: Semantic Layers, Metadata & Trust in 2026

In this episode of the AtScale Data-Driven Podcast, Dave Mariani sits down with Juan Sequeda, Principal Researcher at ServiceNow and former Head of the AI Lab at data.world, to explore what’s next for analytics, AI, and trust in 2026. As AI becomes embedded across the enterprise, one issue is emerging as a hard blocker: lack of context. Large Language Models are powerful, but without semantic layers, governed metadata, and shared business definitions, they struggle to produce reliable, explainable answers. Juan and Dave discuss why metadata is no longer “documentation,” but operational infrastructure, and how semantic layers are becoming the foundation for trusted AI systems. They break down why dashboards alone can’t deliver prescriptive analytics, how AI agents are shifting analytics from insights to action, and why enterprises are consolidating around platforms that can govern context at scale. The conversation also covers: Why AI and LLMs fail without semantic context The rise of semantic layers as enterprise AI infrastructure How metadata, knowledge graphs, and governance converge What AI means for dashboards, agents, and analytics workflows The future of tech jobs, systems thinking, and human skills If you’re a data leader, analytics architect, or AI practitioner trying to understand how to make AI trustworthy in production, this episode explains why semantics, not models, are the real bottleneck. 🔗 Learn more about AtScale’s semantic layer and Model Context Protocol (MCP): https://www.atscale.com 🔔 Subscribe for more conversations on AI, analytics, and data infrastructure.

How MCP + Semantic Layers Turn LLMs Into Trusted BI Analysts

Large Language Models (LLMs) are transforming analytics, but only when paired with the right foundation. In this episode, AtScale’s CTO and co-founder Dave Mariani, co-founder Dianne Wood, and product director Petar Staykov show how Model Context Protocol (MCP) and the semantic layer unlock trusted, governed, enterprise-ready AI. You’ll get a full end-to-end walkthrough of Claude using AtScale’s MCP server to: Discover available semantic models via list-models tools Understand metrics, attributes, and dimensional context using describe-model Run fully governed analytical queries, without writing SQL, through run-query Generate insights, summarize trends, and even build dashboards autonomously Learn why LLMs struggle without structured business logic and how semantic layers eliminate hallucinations and governance drift. You’ll also learn how AI will soon help build semantic models, not just query them—enabling faster metric definitions, autonomous metadata generation, and an “army of agents” that maintain semantic consistency as businesses evolve. Key topics in this episode: • Why MCP is the JDBC-moment for LLMs • How semantic layers make AI deterministic, trustworthy, and governed • Real demos of LLM insights far beyond simple Q&A • Automating semantic model creation using agents and SML • The future: AI copilots for BI, analytics, and semantic modeling

The AI Frontier: Semantic Layers for Autonomous Agents with Jens Kröhnert

Dave Mariani and Jens Kröhnert explore the "AI Frontier:” how semantic layers enable AI agents to operate autonomously without hallucinations or governance drift. Both veterans of scaling Microsoft BI stacks on Hadoop, they discuss why machines need semantic context even more than humans do. Topics include the AI Frontier operational model from Microsoft Research, automating semantic model development with Oraylis's Datamate tool, and Model Context Protocol (MCP) as universal infrastructure for LLMs. Dave demonstrates pairing Claude with AtScale's semantic layer to generate insights, identify sales patterns, and design campaigns. All grounded in governed metrics. Independent benchmarks show semantic layers improve LLM accuracy by 4-5x. Essential for data leaders preparing for agentic AI and generative BI at enterprise scale.
