SWEO Community Project: Linking Open Data on the Semantic Web
Linked Data Browsers, Mashups and other Client Applications
This page collects software components that can be used implement applications on top of the Semantic Web. The page is not intended to list RDF toolkits that focus on local RDF processing, but toolkits that perceive the Semantic Web as a single integrated information space and help applications navigate this information space.
Listings of RDF toolkits with a more local perspective are found at SemanticWebTools and Developers Guide to Semantic Web Toolkits
The page is part of the community project wiki:SweoIG/TaskForces/CommunityProjects/LinkingOpenData

Linked Data Mashups
Revyu by Tom Heath. Uses Linked Data from DBpedia to augment reviews, for instance with information about a director for a film.
DBpedia Mobile by Christian Becker and Chris Bizer. Combines Linked Data from DBpedia, the flickr wrapper, and Revyu.
Music Mashup by Yves Raimond. Combines Linked Data from various music related data sources. See also.
Linked Data Client Libraries
This section lists toolkits that provide access to the Semantic Web by dereferencing resource URIs.
Semantic Web Client Library The Semantic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs and by following rdfs:seeAlso links.
Semantic Web client for SWI Prolog This is a small prolog program allowing to see the semantic-web as a single graph, and to browse it.
OpenLink Ajax Toolkit This includes both a Data Access Layer of RDF, SQL, and XML called Ajax Database Connectivity and a collection of RDF aware controls covering: Graph Visualizers, TimeLines, Tag Clouds, Pivot Tables, and more.
SPARQL Endpoint Clients
This section lists toolkits that support applications in querying a remote SPARQL endpoint.
C based sparql-client with mysql like shell sparql-query
- RAP - RDF API for PHP. SPARQL Client
Ajax based visual Query Builder for SPARQL from OpenLink Software
Federated SPARQL Query Engines
This section lists toolkits that enable federated SPARQL queries against a set of SPARQL endpoints.
DARQ - Federated Queries with SPARQL DARQ is a query engine for federated SPARQL queries. It provides transparent query access to multiple, distributed SPARQL endpoints as if querying a single RDF graph. DARQ enables the applications to see a single query interface, leaving the details of federation to the query engine.
Ajax based visual Query Builder for SPARQL from OpenLink Software
Semantic Discovery System provides for federated SPARQL(commercial product)
