JavaGit is a Java API that provides access to git repositories. The goal is to bring the power of git to the Java world as an API that is intuitive for developers new to git and developers who are veteran git users. It is engineered to provide the developer with access to the raw git commands through a command API as well as an object API designed to represent the .git repository, the working tree, and other familiar git concepts. JavaGit uses the git binaries installed on the host machine to provide git functionality, and has been designed to easily accommodate additional methods of access to git repositories.
Nuxeo Core is an embeddable document management core, based on Nuxeo Runtime. It provides all the necessary low-level services to define, store, manage, audit, request, and search content. It is the "kernel" of Nuxeo 5 and can also be embedded in third-party applications to provide advanced content management features. It can run on any Java 5 platform, can be easily extended using plug-ins, and implements JCA (Java EE Connector Architecture) to be easily plugged into existing applications or information systems.
The Virtual Observatory Quantity Data Model (VOQDM) package is a "thing"-based data model for use with scientific and mathematical data in the International Virtual Observatory (IVO). It is built upon the QML (Quantity Model Language) package and, in general terms, enables fast, convenient serialization/deserialization/manipulation of Quantity-based objects and documents. An important specific application for this package is to enable the I/O of VO-catalog-based data.
Red-Piranha is a search system that can actually learn what you are looking for. It can be used as a Web page, command line, or XML-WebService, so it will work with most languages, including Java, Perl, C#/.NET, and PHP. It includes learning abilities for the Desktop/Internet search functionality. All feedback from the user is stored in (editable) XML and RDF, and is used by the system to improve the quality of searches.
