jena.jar Jena 2.6.2 http://jena.sourceforge.net/ Licensing not yet documented. In executable releases of Votorola, jar files are relocated to votorola/a/web/context/WEB-INF/lib/. (At least until Tomcat learns to obey JAR extensions, per the manifest Class-Path.) THREAD SAFETY jena/doc/how-to/concurrency.html: It's not spelled out in the docs, but apparently only the models are unsafe. The static ModelFactory methods, for example, appear to be safe. It's also not clear whether the locks are necessary for all calls into a model, including single calls; or only to atomicize across multiple calls. JARS The jars were taken from the Jena ARQ distribution, which was more up-to-date at the time. See ARQ-2.8.3/lib and ARQ-2.8.3/doc/Licenses/index.html.
