Jena

Jena is an open-source software framework developed by Apache that helps computers understand and process information on the web. It allows for creating, storing, and querying data structured in a format called the Web Ontology Language (OWL). Essentially, Jena enables applications to manage complex data relationships, making it useful for building intelligent systems like semantic web applications that can interpret and connect information more meaningfully. It’s widely used by developers to build systems that require advanced data integration, reasoning, and knowledge management capabilities.
