About the Book
Protégé Pizza is a practical, step-by-step companion guide to the classic pizza.owl ontology demonstration. Moving beyond static documentation, this book bridges the gap between semantic technologies and real-world implementation. It delivers hands-on workflows for building ontology-based meta-models, deploying knowledge graphs, and applying "Diagramming as Code" methodologies. Developed "Lean-style," the content evolves continuously alongside live video tutorials, offering a data-driven blueprint for mastering Executable Knowledge Architecture (EKA) from the ground up.
