Redland is a set of free software libraries that provide support for the Resource Description Framework (RDF)

Swoogle is a search engine for the Semantic Web on the Web. Swoogle crawl the World Wide Web for a special class of web documents called Semantic Web documents, which are written in RDF. Currently, it provides the following services to the following services: * search Semantic Web ontologies * search Semantic Web instance data * search Semantic Web terms, i.e., URIs that have been defined as classes and properties * provide metadata of Semantic Web documents and support browsing the Semantic Web. * archive different versions of Semantic Web documents

SchemaWeb is a directory of RDF schemas expressed in the RDFS, OWL and DAML OIL schema languages. SchemaWeb is a place for developers and designers working with RDF. It provides a comprehensive directory of RDF schemas to be browsed and searched by human agents and also an extensive set of web services to be used by software agents that wish to obtain real-time schema information whilst processing RDF data. RDF Schemas are the critical layer of the Semantic Web. They provide the semantic linkage that 'intelligent' software needs to extract value giving information from the raw data defined by RDF triples.

The aim of the pOWL project is thus to deliver a PHP and web-based ontology edititing and management solution to the OpenSoure community.

Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine. Jena is open source and grown out of work with the HP Labs Semantic Web Programme. The Jena Framework includes: * A RDF API * Reading and writing RDF in RDF/XML, N3 and N-Triples * An OWL API * In-memory and persistent storage * SPARQL query engine

The Metatomix Semantic Toolkit is a set of Eclipse plugins to allow developers to create and manage ontologies based on the OWL and RDF standards.

Redfoot is a hypercoding system which is being used to create a webized operating system and is also being used to create applications. It is built around the notion of an RDF Graph for persistence rather than a File Tree. It provides standard web mechanisms to transport information across different machines and programmatically specifies the tasks for bundling and installing new software features across networked machines. The functions of Redfoot are analogous to that of an operating system kernel that manages resources across the web. To allow humans and other HTTP service agents to utilize Redfoot, it uses RDFLib and third party libraries such as Twisted and Kid to convert between RDF-based information and HTML or other popular formats. Therefore, each Redfoot server, is designed to interacting with a human, other redfeet, or any other HTTP-aware computing service. The design and implementation principles of Redfoot is to recursively utilize existing standards and libraries whenever and whereever it can, resulting in a highly compact, yet functionally rich execution kernel.

SKOS ou Simple Knowledge Organisation System (système simple d'organisation des connaissances) est une famille de langages formels permettant une représentation standard des thésaurus, classifications ou tout autre type de vocabulaire contrôlé et structuré. SKOS est construit sur la base du langage RDF, et son principal objectif est de permettre la publication facile de vocabulaires structurés pour leur utilisation dans le cadre du Web sémantique. SKOS est actuellement développé dans le cadre du W3C.

The openRDF.org site is a community site that is the center for all Sesame-related development. Sesame is an open source RDF framework with support for RDF Schema inferencing and querying.

RDFa est un projet du W3C pour rajouer des attributs sémantiques à XHTML, un concurrent aux microformats. "RDFa is a set of extensions to XHTML being proposed by W3C. RDFa uses attributes from XHTML's meta and link elements, and generalises them so that they are usable on all elements. This allows you to annotate XHTML markup with semantics. A simple mapping is defined so that RDF triples may be extracted."
