stupid-xml is a ridiculously simple annotation-based XML stream parser for Java. The main goal of this project is to get the strings you care about out of XML and into Java as quickly as possible. You define a simple model class, specify the relative paths for its fields, and it will start generating instances for you from an XML stream. The functionality is limited. It will only parse Strings into your model, but this keeps everything extremely simple. Once you have the Strings in your model, you can perform filtering or more complex conversions.
The Chameleon Problem Solving Environment is based on the CPACS data format and allows third party application coupling for multidisciplinary simulation. It comprises a set of libraries and integration components for the commercial integration environment ModelCenter or the open source alternative RCE (http://www.rcenvironment.de/). It was initially developed from the German Aerospace Center (DLR).
TIXI is a fast and simple XML interface library for applications written in C, C++, Fortran, Java, and Python. Although simplified and somewhat restricted compared to a fully-fledged XML processing library, it can create documents, create and delete nodes, and add and remove element attributes. Routines for reading and writing text nodes and nodes holding integer and floating point numbers are included, along with routines that process aggregates of these simple types for the processing of geometric data, multidimensional arrays, or arrays of vectors.
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.
Ding is a PHP framework that provides dependency injection (by Setter, Constructor, and Method), Aspect Oriented Programming, XML, YAML, Events support, and some JSR 250/330 annotations as bean definition providers, lightweight, can be deployed as a PHAR file, simple, and quick MVC, syslog, TCP client and server with non-blocking sockets, timers, and custom error, signal, and exception handling, PAGI integration (for the Asterisk gateway interface), and PAMI integration (for Asterisk management). It is similar to Java's Seasar and Spring.
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.
