MetaRuby contains miscellaneous libraries (useful now) for a future Ruby-in-Ruby interpreter including Array/Hash/String as abstract ("Hollow") classes, an undo queue, a statistical time-profiler, an event loop, a modular marshaller ("ToSource"), a specification for a modular+reflexive+homoiconic remote call system ("LGRAM"), a declarative type system, a schema for expressing Ruby source code as proper (non-special) Ruby objects, etc.
MQS (Minimalist Queue Services) is a minimalist queueing system that provides a set of basic methods in order to offer asynchronous messaging for program/application. Applications can use this type of services in order to store and retrieve messages to a dedicated queue in the queue services. This allows you to avoid direct connection between applications and provides a simple asynchronous communication system. It provides a simple set of XML-RPC methods for pushing and getting messages in a specific queue (so you can use the system with any application that can talk XML-RPC). The queues are stored in a database (e.g., MySQL) or in dedicated db files (e.g. QDBM).
Momoko is a generic, object-oriented, modular, extensible environment for creating multi-user environments. It is suitable for writing MUDs, servers, and community-based Web sites. It is written in pure Java and supports Java and Python as internal scripting languages. Momoko provides facilities for organizing objects into tree-based hierarchies, orthogonal persistence, a transparent distributed objects system, remote access to source code and user files via WebDAV, a telnet-enabled shell for manipulating the object database, and an integrated build process which can be triggered remotely.
MynahSA is a cross-platform toolkit for connecting C++ objects to data streams. Developers using MynahSA can quickly and easily create client/server applications or encrypted files containing serialized object data. The toolkit uses OpenSSL for encryption and secure network communications. MynahSA is tested on Linux, Microsoft Windows, Apple's Mac OS X, and Sun's Solaris.
OjBect Console is a Web application that provides administrative facilities for the Object Relational Bridge (OJB) persistence framework. This console provides transparent browse, search, create, update, and delete functionality for the objects configured within OJB. In addition, it provides administrative functionality such as cache management and a configuration viewer. Finally, it can be extended to build a data management Web application. The general idea is to provide a useful administrative tool to OJB and a solid reference application for OJB/Struts.
