Stardog

Stardog is a knowledge graph-powered semantic layer platform designed for enterprise use. It unifies enterprise data where it resides and adds semantic context to make that data understandable for AI agents, without locking users into a proprietary environment. The product is intended for data engineers and scientists, as well as organizations in industries such as financial services, government, life sciences, and manufacturing. Key capabilities include streamlining data analytics through a knowledge graph-powered semantic layer, explainable AI, and reusable data modeling, which allows users to create and expand semantic data models, understand data interrelationships, and run federated queries. Stardog also offers graph data virtualization and a graph database, enabling connections to data lakehouses, warehouses, or other enterprise data sources without moving or copying data, with the aim of reducing infrastructure costs. Additionally, the platform applies expert knowledge dynamically at query-time to uncover hidden patterns or unexpected insights in relationships, supporting data-informed decision-making. The product is positioned as an open, purpose-built Semantic AI Platform for the enterprise.
