A web application that is based on the use of linked data resources to generate web pages, so it takes as input an article written by a journalist for example, and the output is a web page containing relevant information extracted from the original article and related content from the linked data cloud. In other words, the application uses the linked data resources to dynamically aggregate output pages, based primarily on SPARQL queries. These are the emails of developers, do not hesitate...

This project is no longer actively maintained. It is succeeded by the Eclipse RDF4J project, which can be found at GitHub and at http://www.rdf4j.org/. Sesame is a de-facto standard framework for processing RDF data. This includes parsing, scalable storage, reasoning and full SPARQL 1.1 query/update support. Sesame offers a fully modular toolkit and an easy-to-use Java API that can be connected to all leading RDF storage solutions.

dotNetRDF is a .Net Class Library for working with RDF and SPARQL programatically built with C# 3 for the .Net Framework 3.5/4.0/Silverlight 4 and WIndows Phone 7. It provides a simple object model for representing RDF, SPARQL Queries and Updates and understands all common RDF and SPARQL syntaxes. Extensive documentation is available on the website and support is available via the mailing lists.

A Windows GUI application for RDF. SWC is a client tool for a Sesame 2 RDF server or SPARQL endpoint, and can be used as a out-of-the-box local triplestore. It offers advanced SPARQL querying and handles Sesame server administrative tasks. This tool is no longer actively maintained as my priorities and interests have shifted away from .Net development. If you are interested in taking over, drop me a line.

A library to allow query a SPARQL end-point in Python

SemaRule Navigator is an Integrated Suite of Open-Source and Free-License Software, placing Semantic and Text Analysis Technologies in the toolbox of Researchers, Students, and Enterprises.

Spreadsheet-to-RDF wrapper capable of transforming spreadsheets to arbitrary RDF graphs; supports mapping language with powerful formula expressions as you know from Excel, local/remote Excel/ODF/CSV, SPARQL service - source available at https://github.com/theandyl/xlwrap

A project designed to create a standard mapping of RDF to Java.

Redland is a set of object-based, modular and portable C RDF libraries providing RDF APIs for the graph, triple storage (librdf), RDF/XML parsing and serializing (Raptor), SPARQL RDF querying (Rasqal). Language APIs in Perl, PHP, Python, Ruby and others.

SPARQL to Object Oriented eNgine allows users to expose their traditional data sources (RDBMS, OODBMS, XML, LDAP, ecc) as RDF data, through a SPARQL endpoint.

SAIM allows to interlink knowledge bases in the Semantic Web. It focuses on instance matching of very large knowledge bases available as SPARQL endpoints. SAIM uses machine learning techniques and is compatible with SILK.

*** PROJECT NOT MAINTAINED ANYMORE *** RDFStats generates statistics for RDF datasets behind SPARQL-endpoints and within single RDF documents.

DB2RDF is a a software tool that will convert data from relational data model to semantic data model (in the form of RDF and RDFS). A SPARQL endpoint for querying the converted data. For querying the semantic data, SPARQL query language is used.

An implementation (parser/interpreter) of SPARQL, a query language for RDF data that is the current recommendation of the W3C. Allows easy cusomization of the language and plugs in to several popular RDF servers, like Sesame.

An experiment in implementing and enhancing the Java Content Repository API with a view to integrating RDF, SPARQL, OWL and related specifications.
