XPLC is a component system that tries to enable the use of components in a pervasive way. It aims to be easy to use, have low speed and size overhead, and be language and platform neutral. Basically, the idea is to leave no excuse for an application not to be component-enabled (being a component and/or using components).
XParam is an extensible, type-safe, non-intrusive, object-oriented tool for general-purpose object serialization and deserialization in C++, good for parsing command-line parameters and cross-program/cross-platform communication. It can handle named parameters as well as object streams. It recognizes class hierarchies, abstract interfaces, and polymorphism, and can therefore serve as a plug-in management framework (e.g., for strategy management).
Zoidcom is a high level, UDP based game networking library for C/C++. Applications register their gameobjects with Zoidcom, and Zoidcom will manage when which object and which internal data of that object is sent to whom. It uses bitstreams as a native datatype and thus is very bandwidth efficient. Support for background file transfers, synchronization of player movement with extrapolation and client side prediction, and many other things are included.
elemenope is an Enterprise Application Integration, Service Oriented Architecture, and general messaging framework. It provides the capability for massive decoupling of an enterprise's components through standardized interfaces for communications. It provides complete abstraction of both transmission protocol and functional components. A project may connect components via a particular protocol standard, and completely change the protocol technology deployed with a simple change to a configuration file, i.e. no code changes. It implements the following connector sets: JMS, SOAP, XML-RPC, direct call, and native IBM MQSeries. It allows an organization to easily create a large scale multi-platform application to conduct messaging or transaction processing. It simplifies architecture of large systems by standardizing functional components and message pathways.
Encdec encodes and decodes C objects such as integers, IEEE754 float and double values, times, and internationalized strings to and from popular binary formats and a wide variety of character encodings as they might appear in various file formats or network messages. It is compiled directly against the libiconv sources.
The gLite distribution is an integrated set of components designed to enable resource sharing. In other words, this is middleware for building a grid. The gLite middleware is produced by the EGEE project. The distribution model is to construct different services ("node-types") from these components and then ensure easy installation and configuration on the chosen platforms.
