RXP is a validating XML parser written in C. RXP project is used by the LT XML toolkit, and the Festival speech synthesis system.

The current version of RXP supports XML 1.1, Namespaces 1.1, xml:id, and XML Catalogs. To use an XML Catalog, set the environment variable XML_CATALOG_FILES to a space-separated list of catalog files.

You can try using RXP to check an XML file.

JCR also know as jcodereview is a web application for performing and managing code reviews.
Although it has some special smarts for reviewing Java projects, it can be used for reviews of any type of source code.
Main features:
- Reviewers. All changes to code are highlighted, and context is shown when adding comments. If reviewing Java code, references to other classes within the file are clickable, so that you can drill into the detail if required. After review comments have been made, those comments can themselves be reviewed, and the required actions decided on and tracked
- Project owners. Review projects are easy to create and configure
- Process Nazis. Details of all comments are held in the database, along with any actions required, and whether theyve been completed. Status reports can be viewed at any time
- Architects and developers. As well as viewing the comments made for a project, its possible to see details of all review projects and comments for a specified file.
At work (Dialect Solutions), we use JCR to review more than half of the code we write. Its made a huge difference to our review process - code reviews now take less time, and the code gets reviewed much more thoroughly than it did in the past.
JCR is released under the GNU Public Licence.

Glan is a toolkit for developing network GUI applications. It consists of a remote Qt toolkit, a network (client-server) wrapper for Qt classes, and a Qt-based Application Server development platform for creating GUI oriented client-server applications.

Glan allows the developer to just write code using the Qt programming style for the server side and forget about the client side.

Glom allows you to design database table definitions and the relationships between them.

The design is loosely based upon FileMaker Pro, with the added advantage of separation between interface and data. It attempts to provide a simple generic framework sufficient to implement most database applications. These systems normally consists of lots of repetitive, unmaintainable code.

Glom-specific data such as the relationship definitions is saved in the Glom document. Glom re-connects to the database server when it loads a previous Glom document. The document is in XML format.

Glom uses the PostgresSQL database backend but it can not edit databases that it did not create, because it uses only a simple subset of Postgres functionality.

GPAC is an implementation of the MPEG-4 Systems standard (ISO/IEC 14496-1) developed from scratch in ANSI C.
The main development goal is to provide a clean (a.k.a. readable by as many people as possible), small and flexible alternative to the MPEG-4 Systems reference software (known as IM1 and distributed in ISO/IEC 14496-5). The MPEG-4 Reference software is indeed a very large piece of software, designed to verify the standard rather than provide a small, production-stable software.
GPAC is written in ANSI C for portability reasons (embedded platforms and DSPs) with a simple goal: keep the memory footprint as low as possible.
The second development goal is to achieve integration of recent multimedia standards (SVG/SMIL, VRML, X3D, SWF, etc) into a single framework. This stage is still under drafting but has started with VRML97 support.
GPAC already features 2D and 3D multimedia playback, MPEG-4 Systems encoders/multiplexers and publishing tools for content distribution.
GPAC is licensed under the GNU General Public License (see FAQ).
The current GPAC release (0.2.3) already covers a very large part of the standard, and features what can probably be seen as the most advanced and robust 2D MPEG-4 Player available worldwide, as well as a decent 3D MPEG-4/VRML player with some X3D support.
GPAC is currently running under Windows, Linux platforms - WindowsCE/PocketPC platform is not actively maintained but GPAC 0.2.3 is running on an iPaq device.
Main features:
- MP4 and 3GPP file reading, both local and through http download (QuickTime FastStart).
- MP3 (local and http) and ShoutCast.
- AAC file reading and AAC http streaming (needs latest faad2 cvs tarball).
- Media Codecs: MPEG-4 Visual Simple Profile, MPEG-4 Audio AAC, JPEG, PNG, AMR audio and all codecs supported by the FFMPEG library (including AVC/H264).
- All media containers supported by the FFMPEG library: avi, mpeg, vob, etc...
- Xiph.org Media: Ogg file format (including http read and Icecast), Vorbis audio and Theora video.
- 3GPP Timed Text / MPEG-4 Streaming Text.
- Streaming support: RTP and RTSP/SDP for MPEG-4 Visual/Audio, MPEG-1/2 audio and video, 3GPP timed text, AMR audio and H263 video.
- Multichannel audio, multichannel to stereo mapper.
- MPEG-4 scenes (2D, 3D and mixed 2D/3D scenes) - read from binary format (BIFS) and textual format (BT/XMT-A).
- VRML 2.0 (VRML97) scenes (without GEO or NURBS extensions).
- X3D scenes (not complete) - supports both X3D (XML format) and X3DV (VRML format).
- JavaScript support for MPEG4/X3D/VRML.
- Compressed description (GZip) supported for all textual formats of MPEG4/X3D/VRML.
- Simple SVG scenes (not complete).
- Simple SWF (Macromedia Flash) scenes (no ActionScript, no clipping, etc).
- HTTP reading of all scene descriptions.

Slibo project is a chess interface and engine for KDE.

Slibo aims to be a comfortable replacement for the xboard chess interface, written for OpenGL and KDE.

It uses the xboard protocol and can be used with common chess engines like crafty or gnuchess, but it provides its own chess engine too.

Though its designed to be easy to use for the new chess player, it supports playing multiple games the same time, or anaylzing PGN files with multiple engines.
