Pinetree
Pinetree is a Linked Data content repository. Content can either be digital content files, e.g. images, or abstract resources, e.g. people, bananas or cats. The system was designed with modularity and flexibility in mind; interfaces and implementations have to a large extent been separated into distinct Maven modules that are highly configurable after compilation through expoiting Spring IoC. Naturally, the integration with Spring makes it possible to exploit and tailor other useful features of this technology, such as Spring security for access control. While Pinetree provides a default configuration for a fresh build, the idea is that an administrator pokes around with the Spring context configuration files to make Pinetree instance behave like desired.
