The 2026 Semantic Layer Symposium (SLS) is the leading forum where industry thought leaders, data experts, and practitioners come together to explore the transformative potential, and reflect on successful implementations of Semantic Layers.

About

Far beyond individual concepts like knowledge graphs, taxonomies, or ontologies, Semantic Layers represent a comprehensive framework for bringing context and meaning to data and content, serving as critical enablers of Artificial Intelligence for your enterprise.

This year’s SLS will maintain its focus on practical applications of Semantic Layers by showcasing real-world use cases, actionable strategies, and proven paths to delivering measurable value. Designed for professionals seeking to move beyond theoretical discussions, the symposium will provide attendees with tangible insights they can apply within their organizations. The SLS is a sponsor-free, sales-free event, focused purely on sharing and connections on this increasingly important topic.

Preceding the main day of the conference, participants also have the option to sign up for an interactive workshop and training day. This workshop and training day will simulate the strategy, design, and implementation of a Semantic Layer and its core Semantic Components (taxonomy, ontology, business glossary), serving as an intensive opportunity to learn how to implement a successful Semantic Layer from the world experts on the topic.
