Ontology-First Knowledge Graphs: Understanding RDF and Building Connected Data Systems

Learn about Knowledge Graphs, their fundamental concepts, and practical applications in this comprehensive conference talk from Netflix software engineer and ontologist Alexandre Bertails. Explore the foundations of Resource Description Framework (RDF) and discover how to create and validate ontologies from scratch. Understand how factual statements are structured in connected graphs to represent real-world resources and relationships. Gain insights into major RDF vocabularies and learn why Netflix has adopted an Ontology-First strategy for data connectivity. Drawing from his extensive experience implementing RDF at organizations like apple.com and the French National Library, as well as his work with W3C standards, Bertails provides deep intuitions about Knowledge Graph architecture and demonstrates their growing importance in modern data management.
