Orient Key/Value Server is based on the Document Database technology and is accessible as an embedded repository via Java APIs or via HTTP using a RESTful API. It uses a new algorithm called RB+Tree, derived from the Red-Black Tree to maintain tree balance, and from the B+Tree storing the links to records in pages to optimize memory consumption and loading time. Orient Key/Value Server scales out very well in a cluster with thousands of running machines: Orient will divide the load among all the nodes. Clustering, by default, works in auto-discovery mode: when a node starts, it attaches itself to the cluster if one is available. When a node goes down, the cluster automatically rebalances itself.
Dog is a Domotic OSGi Gateway. In other words, it is a software-based gateway used for controlling domotic environments in a vendor-independent way, thanks to its high-level semantic device modeling strategy and its driver architecture that allows it to support different domotic plant technologies.
The Apache ODF Toolkit is a set of Java modules that allow programmatic creation, scanning, and manipulation of Open Document Format (ISO/IEC 26300 == ODF) documents. Unlike other approaches that rely on runtime manipulation of heavy-weight editors via an automation interface, the ODF Toolkit is lightweight and ideal for server use.
Rythm Template Engine is a general-purpose, high-performance Java template engine which uses a Razor-like syntax. It is 2-to-3 times faster than Velocity. It supports variables, expression evaluation, control flow (if-else-if), looping, template inheritance(decoration/layout), and many features. There is a Play!Framework plugin based on Rythm. You can use Rythm in any place to generate any type of text file, including HTML, XML, Json, SQL, and any kind of source code.
