Your agents, *governed* to reach it. OpenLink connects AI agents to the enterprise systems that matter. We make your databases, knowledge bases, files, and APIs usable by AI agents—without giving up control of the data or the systems behind it. Our open, loosely coupled architecture combines trusted data connectivity, governed knowledge graphs, and AI-agent harnesses and skills, so agents can work from the enterprise’s own systems of record. Your data. Your rules. Your choice of AI. [Explore the Platform](urn:osdi:sitevirtuoso/) [Book a Scoping Call](urn:osdi:siteprofessional-services/#contact) Founded 1992 · Hosts DBpedia · ODBC · JDBC · SPARQL · SQL · MCP AI works best when it works with the data you already have. 1. **OPAL** puts AI agents, skills, and tools to work. 2. **Virtuoso** connects them to governed data spaces. 3. **UDA** connects Virtuoso to your existing systems. 4. **Our engineers** put it into production and train your team. One stack. Loosely coupled. No rip-and-replace. Trusted for enterprise data connectivity since 1993 30+ Years building data-access middleware 20+ DBMS & data sources supported 4 Standards: ODBC, JDBC, SPARQL, SQL 1 Governed engine for SQL + knowledge graphs "Tired of Data Silos" claims, ported from production's home page (www.openlinksw.com/, section#solutions; website-matrix/www/live/index.html and the 2026-10-15 fetch in production-comparison-2026-10-15/evidence/www/dl/home.html). Headings and copy are production's; the icons are production's SVG paths. Why OpenLink ## Tired of data silos and complex integrations? We provide the universal key to all your data sources, simplifying access and accelerating your insights. ### Semantic Harmonization Achieve high-performance, seamless semantic harmonization of data across all your data spaces — including databases, knowledge graphs, filesystems, and APIs. Our standards-compliant connectors provide the foundation for powerful agentic workflows, all without vendor lock-in. ### Blazing-Fast Performance Engineered for speed and efficiency. Our high-performance data drivers and Virtuoso Data Spaces Platform reduce latency and empower your applications with the speed they need to excel. ### Fine-Grained Security Protect your most critical asset. Leverage the latest encryption protocols and fine-grained, attribute-based access controls (ABAC) to ensure your data is secure in transit, at rest, and during processing. The portfolio ## Five products. One job: get your data to whoever⁠—or whatever⁠—needs it, within the constraints you define. Each product stands on its own. Together, they remove the excuse for a new AI initiative to fail against real enterprise data. OPAL AI Agent, Skill & Tool Platform Where you create and deploy AI Agents, Skills, and Tools. A Tool exposes a Virtuoso SQL Stored Procedure or an OpenAPI-compliant Webservice as an MCP-accessible interface, loosely coupled to the Data Space beneath it — so nothing above has to be rebuilt when something below it changes. Explore OPAL → Virtuoso Universal Server for Data Spaces & AI Agents A converged multi-model DBMS, knowledge base/graph, HTTP application server, document/file server, and data-virtualization engine — natively, in one server — that harmonizes tables, graphs, files, and APIs into a governed layer without copying anything out. Explore Virtuoso → UDA Universal Data Access — ODBC · JDBC · ADO.NET · OLE DB The connectivity layer BI tools have used for three decades now reaches MCP servers and agent frameworks the same way — same drivers, same security model, no new integration to build or trust. Explore UDA → YouID Verifiable Identity for People, Organizations & Agents Cryptographically verifiable identity at Web and Internet scale, usable with PKI and DPKI — separating identity, identification, authentication and authorization instead of conflating them. The same foundation carries On-Behalf-Of delegation, which is what lets an AI Agent prove it acts with the authority of a human, an organization, or another Agent. Explore YouID → Services sits last and spans both columns: with five cards in a two-column grid the final one would otherwise sit alone at half width, reading as an afterthought rather than the close. Professional Services Forward Deployed & Inward Redeployed Engineering Our engineers get an AI initiative from demo to production on your systems. Your engineers get reskilled alongside them — so the capability, not just the software, stays when the engagement ends. Explore Professional Services → VOICE band for the home page (user-approved 2026-10-28), between the product cards and "How the pieces fit". VOICE ## Your Data. Your Know‑how. Any Agent. Any LLM. VOICE — the Virtuoso Open Interoperable Context Engine — combines Virtuoso, OPAL, and LOAM (Linked Open Agent Memory) into a loosely coupled infrastructure for AI agents: governed access to your existing Data Spaces, persistent memory, and the ability to act, through open standards. [Explore VOICE →](urn:osdi:sitevoice/) [Meet LOAM →](urn:osdi:siteloam/) How the pieces fit ## Three steps, no data movement 01 — Connect UDA reaches your sources ODBC and JDBC drivers attach to Oracle, SQL Server, PostgreSQL, Databricks, Snowflake, and 20+ other systems exactly where they already run. 02 — Harmonize & Govern Virtuoso makes it one layer R2RML and RDF Views map every source into a shared semantic model in place, with fine-grained ABAC access control applied uniformly. 03 — Build & Deploy Agents OPAL is the harness for Agents, LLMs, Skills & Tools OPAL is a harness that loosely couples Agents, LLMs, Skills, Tools, and Data Spaces. You create and deploy Agents, Skills, and Tools in it. Tools expose Virtuoso Stored Procedures and OpenAPI Webservices as MCP-accessible interfaces, loosely coupled to the governed Data Space beneath them — versioned artifacts, not one-off integration code. "Built for Your Role" tabs, ported from production's home page. Production renders them by embedded SPARQL over https://www.openlinksw.com/data/turtle/general/general-personae.ttl; the names, headlines, text and images below are that graph's values as the live page rendered them on 2026-10-15 (evidence/www/dl/home.html, extracted to notes/www-src/home-personas.json; all five images checked 200 image/png). Markup and behaviour are the UDA page's (personas-* classes, js/personas.js, #persona- opens a role). Production's "How we help you ..." links go to /personas/* pages that are 404, so they are not carried over.
