Jena wiki:About
From Jena wiki
Jena is a semantic web framework written in Java.
Jena is open source. Development and distribution is done via SourceForge.
The main website for Jena is http://jena.sf.net.
Jena can be used with other languages where the implementation runs on a JVM, such as JRuby or SISC (a Scheme implementation).
Jena also works on .Net and Mono, converting the jar files to .Net DLL using IKVM. It can then be used from C#, Visual Basic and any other language providing access to the CLR.
