neonto Graph IDE Documentation

neonto Graph IDE turns VS Code into a full RDF and Semantic Web IDE: authoring, validation, reasoning and ETL for linked data — plus a built-in MCP server that exposes the same tooling to AI coding agents.

Capabilities​

  1. Authoring — Syntax highlighting, autocompletion, hover documentation, diagnostics, and formatting for Turtle, SHACL, SPARQL, TriG/N-Triples, and YARRRML files. See Working with Turtle.
  2. Querying — Write and run SPARQL queries against local files and remote endpoints, including authenticated ones. See Query Your Graph.
  3. Validation — Manage SHACL validation connections, run validations live or on-demand, inspect detailed reports, and visualize your shapes in an interactive SHACL UI. See SHACL Validation.
  4. Reasoning — Run RDFS and OWL RL reasoners over your Turtle data to infer additional triples. See Reasoning.
  5. ETL mapping — Materialize triples directly within Visual Studio Code. Map CSV, JSON, or XML sources to RDF using YARRRML, auto-convert to RML/R2RML, and run your ingestion pipelines without leaving the editor. See Ingestion & ETL.
  6. AI-agent integration — An in-process MCP server exposes validation, querying, vocabulary discovery, and triple generation to your favorite AI agent, including Claude Code, GitHub Copilot, or OpenAI Codex. See Agentic AI.
