Your data, wherever it lives.
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.

AI works best when it works with the data you already have.
- OPAL puts AI agents, skills, and tools to work.
- Virtuoso connects them to governed data spaces.
- UDA connects Virtuoso to your existing systems.
- Our engineers put it into production and train your team.
One stack. Loosely coupled. No rip-and-replace.

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.
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.
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 →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 →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 →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 →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 →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.
Three steps, no data movement#
Built for your role#
Our solutions are tailored for every data professional.
Build AI Agents & Skills on a semantically rich foundation
Ensure the development and deployment of AI agents and skills informed by semantically rich data, information, and knowledge across your enterprise—delivering agility without introducing new silos or compounding technical debt.
Make loosely coupled data, information, and knowledge the norm
Design and implement a loosely coupled architecture for AI agents and skills using open standards, knowledge graphs, and interoperable data access—connecting databases, documents, APIs, and semantic layers without creating brittle dependencies.
Build intelligent applications with open standards and portable skills
Develop high-performance applications, APIs, and AI agents using standards-based connectivity and query technologies including ODBC, JDBC, ADO.NET, SQL, SPARQL, GraphQL, and REST—while integrating seamlessly with relational databases, knowledge graphs, vector stores, and document collections.
Operationalize trustworthy AI with enterprise context
Deploy AI agents and intelligent workflows grounded in enterprise data, governed knowledge graphs, and semantically enriched retrieval pipelines—improving explainability, contextual accuracy, interoperability, and long-term scalability across your organization.
Extend your platform with trusted connectivity and AI infrastructure
Partner with OpenLink to embed standards-based connectivity, semantic interoperability, and AI-enablement capabilities into your products and services—supported by proven integration expertise for ISVs, OEMs, system integrators, and enterprise solution providers.
Ready when your data is
Bring one AI initiative that's stuck between demo and production.#
We'll tell you — specifically, and at no charge — what's blocking it, and which pieces of the portfolio fit. If we're not the right fit, we'll say so on the first call.
