The SKOS API is a Java interface and implementation for the W3C Simple Knowledge Organisation System SKOS. For more information about SKOS see here. An implementation of the SKOS API is provided which uses the OWL 2 API, at present you will need to obtain the OWL API seperately from the OWL 2 website. [UPDATE 12-09-2011] The current release of the SKOS API has been deprecated, a new version_3 developer branch is available in the SVN repository that works with the latest OWL API v3.
For more information please contact the user group at skos-dev@googlegroups.com
The SKOS API is open source and is available under the LGPL License
The SKOS API includes the following components:
An API for the major SKOS constructs and an efficient in-memory reference implementation based on the OWL 2 API
Abstract data model for working for SKOS that avoids commitment to any of the concrete syntaxes, such as RDF
RDF/XML parser and writer
OWL/XML parser and writer
OWL Functional Syntax parser and writer
Turtle parser and writer
Support for extending the underlying SKOS data model via the OWL 2 API
Support for integration with reasoners such as Pellet and FaCT++
Range of convenience methods for working with SKOS
Java applications are typically deployed in multiple environments and platforms, each requiring some unique configuration. JFig gives developers a simple yet powerful tool to manage their applications’ configuration. It allows them to:
1. Store application configuration in one common repository of XML files
2. Access configuration data using one common, convenient interface
3. Easily define multiple configurations, dynamically modifying those variables that need to change in different situations
4. Eliminate the error prone practice of defining the same configuration variables in multiple locations
5. Ease the management, deployment, and control of configuration files
SCPSolver should enable a Java developer to use Linear Programming in less than 10 minutes.
Most solvers for linear programs are implemented in C/C++ for performance reasons. Java developers can use JNI interfaces for some solvers. However most interfaces are pretty difficult to setup, and lock the developer in to a specific solver. SCPSolver was developed to overcome those issues. The library has the following features:
easy to deploy on Linux, Mac Os X and Windows with prebuilt linear programming libraries (almost dependency-free)
plugin-concept: write model, use different solvers to solve it
currently supported solvers:
GLPK
lpsolve
CPLEX (solver pack must be built by script by user)
low learning curve: very simple, no-frills API
other features: implementation of sparse matrices and graphs, debugger for linear programs, prebuilt models for common optimization problems like set cover, ...
The Doolin framework allows the rapid development of Swing applications. It uses the Spring framework as a support for its configuration and extensibility.
Normally smartphone events are tightly coupled to your phone device itself. When your cell phone is ringing, your phone speaker plays a ringtone. When you get a new text message, your phone displays it on its screen. Wouldn't it be thrilling to make thoses phone events visible somewhere else, on your wearable, in your living room, on your robot, in your office or where ever you want it to occur? Or would you like to use your smartphone sensors, like the accelerometer, light sensor, compass or your touchscreen to control other devices? 'android meets arduino' is a toolkit, basically consisting of an Android application and an Arduino library which will help you to interface with your phone in a new dimension. You can build your own interfaces almost without any programming experience.
Apache Shiro is a powerful and easy-to-use security framework that performs authentication, authorization, cryptography, and session management. With Shiro’s easy-to-understand API, you can quickly and easily secure any application – from the smallest mobile applications to the largest web and enterprise applications.
iCal4j is a Java API that provides support for the iCalendar specification as defined in RFC2445. This support includes a Parser, Object Model and Generator for iCalendar data streams.
Hazelcast is an open source clustering and highly scalable data distribution platform for Java, which is:
* Lightening-fast; thousands of operations/sec.
* Fail-safe; no losing data after crashes.
* Dynamically scales as new servers added.
* Super-easy to use; include a single jar.
Hazelcast is pure Java. JVMs that are running Hazelcast will dynamically cluster. Although by default Hazelcast will use multicast for discovery, it can also be configured to only use TCP/IP for environments where multicast is not available or preferred.
PrimeFaces is an open source component suite for Java Server Faces featuring 90+ rich set of JSF components. Additional TouchFaces module features a UI kit for developing mobile web applications.
* 90+ rich set of components (HtmlEditor, Dialog, AutoComplete, Charts and many more).
* Built-in Ajax with Lightweight Partial Page Rendering.
* Native Ajax Push/Comet support.
* Mobile UI kit to create mobile web applications for handheld devices with webkit based browsers.(IPhone, Palm, Android Phones, Nokia S60 and more)
* Compatible and Lightweight.
* Skinning Framework with 25+ pre-designed themes.
* Extensive documentation.
Jspresso is an innovative framework for building rich internet applications. Jspresso dramatically reduces the development cycles needed to get your corporate application up and running while not sacrificing quality, robustness and performance. Jspresso is not just another webapp framework. Jspresso based applications offer the exact same ergonomics as desktop applications while keeping an N-tier, server-centric architecture on a java backend. Jspresso-based applications can be deployed either in Adobe's Flex, qooxdoo, WingS, ULC and Swing, all on the same codebase and without a single specific line of GUI code. And last but not least, Jspresso is free.
Die Roblet®-Technik ist eine in Java™ implementierte Softwareschicht zwischen Anwendung und Übertragungsnetzwerk. Ziel ist, von jeglichen Hardware- und Netzwerkaspekten verteilter Systeme zu abstrahieren, um die Komplexität bei der Entwicklung verteilter Anwendungen signifikant zu reduzieren. Um dieses Ziel erreichen zu können, bietet die Roblet®-Technik Verteilungsfreiheit bei der Zuordnung von Funktionalität, Technikvereinheitlichung für die verteilte Anwendung und Netzwerktransparenz inklusive Datensicherheit.
Katta is a scalable, failure tolerant, distributed, data storage for real time access.

What is Apache Pivot?
Apache Pivot is an open-source platform for building rich internet applications in Java. It combines the enhanced productivity and usability features of a modern RIA toolkit with the robustness of the Java platform. Pivot applications are written using a combination of Java and XML and can be run either as an applet or as a standalone, optionally offline, desktop application.
Like other modern development platforms, Pivot provides a comprehensive set of foundation classes that together comprise a "framework". These classes form the building blocks upon which more complex and sophisticated applications can be built.
