The record

Purpose: RDF Studio is a semantic data workspace for exploring, querying, visualizing, and modeling RDF knowledge graphs.
SPARQL: Its SPARQL editor supports syntax highlighting, autocomplete, PREFIX folding, a query library, and execution history.
Ontology editing: The visual ontology editor supports creating and editing OWL/RDFS classes, properties, and restrictions.
SHACL: The SHACL editor can browse, edit, and auto-generate shapes, and validate them with a validation dashboard and maturity scoring.
Triple stores: The product supports its built-in Oxigraph store and connections to GraphDB, Virtuoso, Stardog, Amazon Neptune, Apache Jena Fuseki, and SPARQL 1.1 compatible endpoints.
Desktop platforms: The maker says the desktop app runs on macOS, Windows, and Linux and works offline without an internet connection.
API: Saved SPARQL queries can be exposed as REST API endpoints.
AI features: AI can propose ontology changes and generate SPARQL from natural-language questions; its proposed ontology changes are drafts for review.
Training content: The Northwind training environment includes a SPARQL query library, a guided CRUD tutorial, an OWL 2 ontology, and SHACL shapes.
Security and compliance: The maker says each user gets an isolated database copy in the training environment; the page does not state a security certification or compliance standard.
Preview status: RDF Studio is described as a preview release under active development, provided as-is and not intended for production or business-critical systems; the maker advises evaluation on test data.
Known limit: The maker says full OWL 2 RL closure at the stated 133-million-triple scale is still slow and on the roadmap.
Intended users: The maker identifies ontologists, data engineers, data analysts, knowledge graph engineers, and technical leaders as users it serves.
Maker: The homepage credits the product as created by M Barbieri.
