The ManEdit UNIX Manual Page Editor is an editor specifically tailored for UNIX manual pages. It has a preview viewer, uses the manual page XML format for easy editing, and comes with a tutorial and reference guide. It uses the GTK+ widget set and features syntax highlighting, a complete drag and drop system for easy viewing and editing, a crash recovery system, and sample manual page templates.
RADpage is a rapid application development system for dynamic, data-driven Web applications. It directly operates inside the browser without requiring a client-dependent development environment. RADpage comes as an Apache module or a CGI, includes a powerful HTML/XML like object-oriented programming language called heitml (pronounced "Hi-TML"), and more than 150 Web application components. Development is done on a fully functional application instead of requiring the edit-save-browse cycle associated with conventional client-side development environments. The RADpage editor stores application pages in readable well-formed XML or upon request in HTML for editing with HTML editors.
Redland is a set of C libraries providing a high-level API for the Resource Description Framework (RDF), allowing it to be stored, parsed, serialized, queried, and manipulated. It has an object-based, modular design and comes with detailed reference documentation and examples. Redland supports all RDF vocabularies such as FOAF, RSS 1.0, Dublin Core, DOAP, and OWL, the query languages SPARQL and RDQL, and all RDF syntaxes including Turtle, RDF/XML, RDF/JSON, RSS, Atom, RDFa, and GRDDL.
Sablotron is an XML toolkit which implements XSLT, DOM, and XPath. Sablotron is written in C++, and it can be used from C, Perl, Python, PHP, ObjectPascal, and via a command line interface. It supports the XSLT 1.0, XPath 1.0, and DOM Level 2 W3C specifications. It is designed to be as compact and portable as possible, and is maintained as an Open Source project by Ginger Alliance.
SDPXML is an XML parser written in C++ with a clean C++ interface, neither DOM nor SAX. Its functionality includes performing XPath and other queries on a loaded XML document, creating and parsing documents with typesafe conversions between XML and C++ objects, and serializing XML documents to streams. By casting-off the DOM and SAX APIs, SDPXML attempts to provide XML services that integrate well with the rest of the C++ standard library.
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.
X-Tract is an XML Script processor. XML Script is a fully XML compliant language, specifically designed for handling XML data. XML Script is more powerful than XSL, and can perform many XSL functions more efficiently. X-Tract can be used on the command line, or can be run from a web server to handle CGI queries.
