Raptor is a C library providing a set of parsers and serializers for Resource Description Framework (RDF) triples by parsing syntaxes into RDF triples and serializing triples into a syntax. The parsers support RDF/XML, N-Triples, GRDDL, and Turtle, and via RSS tag soup: XML RSS, Atom 0.3, and Atom 1.0. The serializers support RDF/XML (3 flavours), Turtle, DOT, N-Triples, RSS 1.0, and Atom 1.0. Raptor handles RDF/XML as used by RDF applications such as RSS 1.0, FOAF, DOAP, Dublin Core, and OWL. It can use either expat or libxml2 for XML parsing, libcurl when available for URI retrieval, and is portable to many POSIX systems.
Studs MVC Framework+ contains a port of Apache's Jakarta Struts to PHP, though the libraries included in the rest of the project are much more vast. In order to implement the Struts port, it was necessary to build a core, object-oriented API in the style of the JDK and the Jakarta Commons, a servlet container to handle HTTP requests and to invoke servlet classes, and finally, a parsing engine for JSP-style template pages. In the end, the result is an environment which is very similar to that provided by a J2EE Web Container, only everything is implemented in PHP. While it was possible to carry over many of the concepts, designs and mechanisms from J2EE, some limitations do exist due to the nature of the PHP programming language, such as the lack of checked exceptions (runtime only).
XWidglets is a complete rich Java Swing tool for designing, creating, and using XML-based GUIs. It provides a lightweight XML client, clear separation between view, data, and process, MVC I and II support, event management, a consistent look and feel across platforms, a rich set of GUI components, and n-tier architecture integration.
Apache XML Graphics Commons is a library that consists of several reusable components used by Apache Batik and Apache FOP. Many of these components can easily be used separately outside the domains of SVG and XSL-FO. You will find components such as a PDF library, an RTF library, Graphics2D implementations that let you generate PDF and PostScript files, and much more.
WSO2 Web Services Framework for PHP is a PHP extension for providing and consuming Web services. WSO2 WSF/PHP supports SOAP 1.1, SOAP 1.2, WSDL generation, WSDL mode (WSDL 1.1 and WSDL 2.0), REST style invocation, integrated Data Services capabilities, and some of the key WS-* stack specifications such as: SOAP MTOM, WS-Addressing, WS-Security, WS-SecurityPolicy, and WS-ReliableMessaging.
Rome is a set of Atom/RSS Java utilities that make it easy to work in Java with most syndication formats. It accepts all current flavors of RSS (0.90, 0.91, 0.92, 0.93, 0.94, 1.0, and 2.0) and Atom 0.3 feeds. Rome includes a set of parsers and generators for the various flavors of feeds, as well as converters to convert from one format to another. The parsers can give you back Java objects that are either specific for the format you want to work with, or a generic normalized SyndFeed object that lets you work on with the data without bothering about the underlying format.
Cypress is an open-source Cascading Style Sheet (CSS) parser that lets you add well-documented, standardized name/value pairs (a.k.a. CSS style properties) to your own XML markup languages. It supports inline styles so you can add style properties to individual XML tags using the style attribute or external style sheets so that you can store style rules for reuse in separate, XML-free text documents. Cypress supports three forms of selectors to match your XML tags and style rules, that is, element selectors, class selectors, and id selectors.
