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.
LuMriX is a search engine that exploits XML and XML Topic Maps. In contrast to other retrieval methods, it does not relate single items to resources, but combines given items into meaningful associations (concepts), which are in turn linked to resources. XML Topic Maps allow an intelligent mapping of relations between terms and pages. The meaning of the query is captured by transverse joint relations between the search items. LuMriX is also able to auto-extend its thesaurus and create new relations between failed search items and information resources. It is completely implemented in Java. It can consist of many individual distributed LuMriX servers, which communicate with each other by distributed algorithms. Standardized interfaces such as TCP, SOAP, HTTP, XML, and XTM allow simple utilization and maintenance by other applications.
Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.
X2U (XML to user) is an XML editor that does not force users to read XML markup. Instead, users fill out simple Web forms, which are automatically derived from XML models. The XML model provides the XML structure and an interface. It accepts an XML document, an XML Schema, a DTD (Document Type Definition), or an XML form (XForms), and requires only a Web browser to use.
TM++ is an embedded, portable, persistent Topic Maps engine. It is designed to work according to the ISO standards for TMDM 1.0 and XTM 1.0/2.0 on Windows and most POSIX-compliant operating systems like Unix and Linux. It has interfaces for C++, ALLEGROCL, CHICKEN, CLISP, CFFI, C#, Guile, Java, Lua, Modula 3, Mzscheme, Ocaml, Octave, Perl, PHP4, PHP5, Pike, Python, R (aka GNU S), Ruby, Lisp S-Expressions, Tcl, Common Lisp/UFFI, and XML.
