Document Structure Description (DSD) is a simple but expressive grammar notation for XML documents. This new XML schema language is result of a research collaboration between AT&T Labs, NJ and BRICS at the University of Aarhus, Denmark. The technology is based on general and familiar concepts that allow much stronger document descriptions than possible with DTDs or XML schemas.
eXist is a native XML database featuring efficient, index-based XPath query processing, extensions for keyword search, XUpdate support, and tight integration with existing XML development tools. The database is lightweight and may be easily deployed in a number of ways, running either as a stand-alone server process, inside a servlet engine, or directly embedded into an application.
JSX serializes Java objects to XML. You can persist objects, evolve them, and send them over the network and between applications. Your object data becomes human-readable and human-writable. You can test it, search it, profile it, audit it, and edit it with ordinary text and XML tools. JSX handles all POJOs and also all classes that require Java's own object serialization.
The Kawa Scheme System is a full Scheme implementation, completely written in Java. Scheme functions and files are automatically compiled into Java byte-codes. Kawa does some optimizations, and the compiled code runs at a reasonable speed. It provides the usual read-eval-print loop, as well as batch modes. The Kawa compilation framework is also useful for implementing other languages on top of JVM. There is active development of XQuery (the XML query language), and less active development of Emacs Lisp, Common Lisp, and EcmaScript.
Xerces2 is the next generation Apache Xerces-J XML parser. This version of Xerces-J defines the Xerces Native Interface (XNI), and provides a complete, standards compliant reference implementation using XNI. The parser was completely re-designed and re-implemented to be simpler and more modular. To help contribute to this project, visit the Apache Xerces Project Webpage (http://xerces.apache.org) and join the firstname.lastname@example.org mailing list.
PCGen is a Java (1.5+) -based character generator aimed at supporting OGL role playing games like those based upon the SRD, RSRD, and MSRD (such as Dungeons and Dragons). It is highly configurable by the users, allowing the Game Master to add or remove races, classes, feats, etc., and to implement house rules such as differing class or race restrictions. Level advancement is also supported, with configurable progressions of feats, skills and ability score bonuses. For "at the table" support, PCGen offers a set of GM plugins. Further options allow the user to produce a customized character sheet, which can then be viewed in, or printed from, the user's WWW browser. It can also produce a "party" sheet with the information needed by the GM.
