Qexo (Query Expressions for XML Objects aka Kawa-XQuery) is an implementation of W3C's draft XML query language XQuery. XQuery is a high-level expression language whose values are sequences of nodes (as in DOM) and simple values. It includes syntax for embedding XML or HTML results, and a 'for' statement comparable to SQL's 'select'. This implementation uses the Kawa tools to compile XQuery programs to Java bytecodes that can run on any JVM. XQuery programs can run as servlets, as standalone applications, or from the command-line.
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.
XMLPublication is a set of tools to generate Web pages from (possibly large) desktop documents or other structured documents, such as books with paragraphs, or tabular data. It cuts documents into Web pages, and creates customizable multi-indices. All this is done through a repeatable process in which data is separated from presentation and user settings. It uses XML techniques, particularly XSLT and Ant.
