Going Meta is a monthly live-stream series hosted by Jesus Barrasa, Principal Engineer and Developer Advocate at Neo4j, covering the intersection of semantic technologies and graph databases. Each episode dives deep into practical, code-first topics — from importing RDF vocabularies and validating graphs with SHACL, to building ontology-driven GraphRAG pipelines and agentic workflows powered by LLMs. With over 46 episodes across three seasons and an active community on YouTube and Twitch, Going Meta has become a go-to resource for anyone building intelligent, structured data systems on top of Neo4j.Documentation Index

Going Meta streams on the first Tuesday of each month at 4pm BST / 11am ET / 8am PT. Sessions are recorded and published on YouTube, with all code available in the GitHub repository.
What You’ll Learn
The series covers a broad spectrum of topics, growing from foundational semantic-web concepts in Season 1 through advanced GenAI integration patterns in Seasons 2 and 3.Semantic Technologies
RDF, OWL, SKOS, SHACL, SPARQL, Turtle serialization, ontology reasoning, and taxonomy management — the building blocks of knowledge representation.
Neo4j & Neosemantics
Importing RDF into Neo4j, configuring graph models with n10s (Neosemantics), running SPARQL against Neo4j, and migrating from triple stores.
LLMs & GenAI
RAG patterns, ontology-driven entity extraction, LangChain and LangGraph agents, automated KG construction, and the
neo4j-graphrag library.Graph Data Quality
SHACL validation, graph expectations, ontology versioning, data reconciliation, and structural pattern analysis across ontologies.
The Three Seasons
Going Meta has evolved over three distinct seasons, each reflecting the expanding frontier of knowledge graphs and AI.Season 1 — Foundations (2022–2024)
27 sessions covering SPARQL, SHACL, RDF integration patterns, ontology reasoning, Wikidata, DBpedia, semantic similarity, and the first explorations of LLM + KG patterns. Includes sessions 1–27.
Season 2 — GraphRAG (2024–2025)
11 sessions focused on ontology-driven KG construction from unstructured data, end-to-end GraphRAG, mixed-data ingestion, retrieval method comparisons, and LLM tool calling with ontologies. Includes sessions 28–38.
Season 3 — Agents & MCP (2025–2026)
Ongoing season exploring Neo4j MCP Server, agentic ontology workflows, SHACL validation, agent memory, and ontology design decisions. Includes sessions 39–46+.
GitHub Repository
All session code, Cypher scripts, Jupyter notebooks, Python scripts, and ontology files are published in the open-source repository after each broadcast.
