Vectors, meet Virtuoso. Native HNSW vector indexing just landed in the Virtuoso Open Source develop/7 branch, with ONNX text embeddings and optimizer tuning alongside. Similarity search across native relational tables via SQL and RDF graphs via SPARQL, one engine. Enjoy!
Can your AI agents use what your core systems know, without a single record leaving them? Yes.
Virtuoso gives them governed, semantically rich context across your databases and knowledge bases. Nothing copied.
Free 15-day evaluation. Then $499 for 5 concurrent users.

- Project Development, $499: shop.openlinksw.com/offers/o…
- Add-on: Multi-Tier ODBC Bridge, $499.99 for up to 5 concurrent users: shop.openlinksw.com/offers/o…
ISO GQL is now in Virtuoso Open Source.
Most GQL stops at labeled property graphs. This one adds hyperlinks as IDs, ontology use, and platform-agnostic knowledge graphs—same move SPASQL made for SQL.

Why GQL on Virtuoso: property-graph syntax over RDF, translated to SPARQL — so you keep the SPARQL engine (optimizer, paths, geospatial) while writing MATCH.

Introducing VOICE, the Virtuoso Open Interoperable Context Engine.
Your data. Your know-how. Any agent. Any LLM.
It takes agents from intent to governed action, with context that grows more valuable over time, and no lock-in to a single data platform, agent harness, or model.
AI agents need live data access, but every connection is also an attack surface. Our Multi-Tier Agent gives agents governed access to SQL Server and Sybase via ODBC, JDBC, MCP and OpenAPI, with identity built into every hop rather than bolted on.
It’s taken some time, but AI agents have finally brought data security back to everyone’s attention.
In a network, security is only as strong as its weakest link: a compromised device used by a compromised entity.
Addressing this requires incorporating identity into the architecture, then applying fine-grained, attribute-based access controls (ABAC)—not role-based access controls—to data access policies across ODBC and JDBC interactions.
That’s what our Multi-Tier ODBC and JDBC drivers have always been designed to do.
Can your AI agents query SQL Server without hardwired, platform-specific connectors? Yes.
Our Multi-Tier Agent for SQL Server & Sybase gives them live, governed access via ODBC, JDBC, HTTP, MCP- & OpenAPI-compliant Services.
$499.99 for up to 5 concurrent users.

Can your Java tools on a Mac reach the ODBC data sources you already have? Yes.
The UDA JDBC-to-ODBC Bridge gives them one fast, secure path, built on open standards, for legacy tools and modern AI agents alike.

Why does every new AI initiative leave you with yet another data silo?
Virtuoso gives your AI agents one semantically harmonized view across your systems of record and analytics. Nothing copied. Nothing ripped out.

Sometimes an agent just needs a HowTo, not a new skill. With agent-rdf-memory, procedures live as shareable knowledge that any harness can use: Grok Bot, Muse, Claude, ChatGPT, Codex and others. Agents, tools and data stay loosely coupled.
Cool. But rather than creating a new skill, sometimes all that’s needed is a new HowTo.
That’s how I handle this workflow: I use our agent-rdf-memory layer alongside various skills across @bot, @Muse, @AnthropicAI’s Claude Desktop and Code, @OpenAI’s ChatGPT Work and Codex, @opencode, Pi, and others.
Can your whole BI team hit PostgreSQL live from one Linux server? Yes.
The UDA Lite ODBC Driver for PostgreSQL, Workgroup edition, serves dashboards and AI agents alike, with no security compromises.

Woot! Virtuoso Full Text now includes Fuzzy Search (Jaro-Winkler, Levenshtein, N-Gram Cosine)—alongside last week’s Vector Indexing & Semantic Similarity Search.
Live in VOS develop/7 (v7.2.18, unreleased): SQL contains() & SPARQL bif:contains.
github.com/openlink/virtuoso…
Additional demonstrations using our new Generic SPARQL-based Faceted Search and Browsing tool, which is also open source:
1. N-gram Cosine Test — linkeddata.uriburner.com/c/4…
2. Jaro-Winkler — linkeddata.uriburner.com/c/C…
Here's a link to the Virtuoso Fuzzy Search documentation.
