Turn VS Code into an RDF and Semantic Web IDE. Author Turtle and SPARQL, validate with SHACL, run RDFS/OWL reasoning, and write your ETL mappings with YARRRML/RML - all inside the editor. You can also expose the entire toolchain to AI coding agents through a built-in Model Context Protocol (MCP) server.
