Mahdi Habibi released v0.1.1 of Knowledge Graphs: Semantic Graphs and Property Graphs, a 156-page illustrated open-access book (CC BY 4.0) on Zenodo.

• Covers graph fundamentals through ontology modeling, querying, validation, and architectural decisions, tying RDF, RDFS, OWL, SPARQL, and SHACL to Neo4j and Cypher
• A running learning-catalog example contrasts how semantic graphs and labeled property graphs handle identity, relationships, constraints, inference, and events
• Applies the concepts to recommendation policies, interoperability, Graph RAG, performance, and governance
• Includes original diagrams, comparison tables, worked code examples, exercises with explained answers, a glossary, and an MIT-licensed companion code repo
