Babel is an IDL-based language interoperability tool specific to engineering and scientific applications. It allows Fortran 77, Fortran 90, C, C++, Java, and Python to call each other in a single address space for maximum performance. Babel won a 2006 R&D 100 award from R&D Magazine.
DataManager is a library that provides a shared memory pool to allocate buffers from. It includes the necessary things to build servers which regulary produce data and provide them via ringbuffers to clients. It includes the common framework to have locking and various access methods. The use generally boils down to simple get()s and put()s. This project is no longer under active development.
GUPnP is an object-oriented open source framework for creating UPnP devices and control points, written in C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient, and flexible. The GUPnP framework consists of two libraries. GSSDP implements resource discovery and announcement over SSDP, and GUPnP implements the UPnP specification: resource announcement and discovery, description, control, event notification, and presentation (basic Web server functionality through libsoup). GUPnP does not include helpers for construction or control of specific standardized resources (e.g. MediaServer); this is left for higher level libraries utilizing the GUPnP framework.
Glib Binding properties is a system that allows developers to bind properties of GLib and GTK+ objects (Ada95 bindings are also available). This makes it possible to synchronize the properties of several objects, so that when one property changes the properties bound with it automatically change accordingly. This often eliminates the need to write callbacks watching for changes of properties. It supports one-way and mutual bindings and bindings with transformation functions.
Jentchina is the client library part of "The Birds Lake" framework. It is independent of any graphical toolkit. Its role is to create the filter trees, to maintain them, and to propose an API that enables the application of a filter the easiest way possible (while remaining independent of any GUI). The Birds Lake is a big framework for applying a filter on a document using a remote filter server.
Keystone is a cross-platform, object oriented application framework which allows applications to be written to build on the target platforms of GNU/Linux and Win32 without modification of their source. Keystone implements several modern Web standards, including SVG graphics and the XUL user interface description language.
Lioubliou is a library part of "The Birds Lake" project. It is used to write filter servers. Lioubliou takes cares of filter sessions, registers servers in local database, and abstracts network messages. It supports CORBA via ORBit, but the design of the library can support other communication media later. It also abstracts lsmlib.
The Pandora Engine SDK is an object-oriented development toolkit that is specially designed for multi-platform use. It allows you to create truly object-oriented programs without being restricted to object-oriented languages like C++. The environment is fully self-contained, which allows for easier porting, and the inclusion of a commercially developed VESA graphics drivers means that you can create full-screen applications that don't require X11. It is intended for creating both applications and games, and is also required to write programs for Athene, a multi-platform operating system that is based on the engine.
