white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
NetCrawler is the frontend to a Web crawling system. This command line application will download all of the pages within a domain, and then parse and process all of the relative content (Images, Text, Audio, Video), saving this content within an XML document for later processing. It is definitely alpha quality, but has been used quite extensively.
xmlizer configurator/server is a client/server approach for custom database to XML mapping. The configurator is used to set up projects and the server delivers the processed requests on demand (like a Web server) according to the mapping rules made with the configurator, which includes a drag and drop GUI. One module is for dumping databases (or parts of it) in a fixed format and the other module can build XML instances satisfying a specified XML Schema (or DTD).
xopus is a browser-based (Mozilla, IE) in-place WYSIWYG XML editor. It works similarly to a word processor, and uses XSLT stylesheets to transform the XML to user-presentable HTML and XML Schema to preserve the XML validity. A commercial version with table, rich text, and enumeration editing is available as well.
GroupServer is a Web-based mailing list manager designed for large sites. It provides email interaction like a traditional mailing list manager but also supports reading, searching, and posting of messages and files via the Web. Users have forum-style profiles, and can manage their email addresses and other settings using the same Web interface. It has supports features such as Atom feeds, a basic CMS, statistics, multiple verified addresses per user, and bounce detection, and is able to be heavily customized.
EZ Reusable Objects (EZRO) is a Web application that can be used by non-technical staff to manage content as "objects." Content objects containing text, video, and audio can be shared, modified, and re-styled to appear via a traditional Web site, an on-line course, an innovative "Coach," or as a community of interest site. It is highly scalable and can be used for public Web sites, secure environments, and private intra/extranets.
