    RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions. SPARQL also supports extensible value testing and constraining queries by source RDF graph. The results of SPARQL queries can be results sets or RDF graphs.

    "The W3C standard query language SPARQL is letting people access a growing collection of public and private data. Whether this data is part of a semantic web project or a combination of data from two relational databases on different platforms, SPARQL is making it easier to access this data using both open source and commercial software. "Learning SPARQL" teaches you how to use SPARQL 1.1 by starting you off with simple queries that demonstrate the language's query-by-example approach and then taking you through all the key features of the SPARQL 1.1 query and update languages. All example "

    The name and tool relies on and/or is inspired by SPARQL, Google visualization API, SPARQLer, Snorql and Spark. All the major chart types offered by the Google Visualization API are supported by Sgvizler. The user inputs a SPARQL query which is sent to a designated SPARQL endpoint. Sgvizler parses the results into the JSON format that Google prefers and displays the chart using the Google Visualization API or a custom-made visualization or formatting function.

    an overview of the SPARQL Inferencing Notation (SPIN). SPIN is a SPARQL-based rule and constraint language for the Semantic Web. SPIN is also a mechanism to represent reusable SPARQL queries as templates and to define new SPARQL functions with a web-friendly syntax.

    SPARQL (pronounced "sparkle", a recursive acronym for SPARQL Protocol and RDF Query Language) is an RDF query language, that is, a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework format.[1][2] It was made a standard by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is considered as one of the key technologies of the semantic web.

Being limited to well-known brand names, it shows only a fraction of of the companies who have done this. Many of these companies have had multiple listings over the last few years-sometimes in the same day."

    The group was started at DrupalCon Barcelona 2007 and includes discussions on how to integrate the Semantic Web technologies into Drupal and list the various effort of the community towards enabling RDF in Drupal. Drupal 7 comes with native RDFa support in core. If you want extra RDF capabilities such as other serialization formats and SPARQL support, checkout the RDF Extensions, SPARQL and SPARQL Views contributed projects.

    SPIN is the de-facto industry standard to represent SPARQL rules and constraints on Semantic Web models. SPIN also provides meta-modeling capabilities that allow users to define their own SPARQL functions and query templates. Finally, SPIN includes a ready to use library of common functions.

    The Virtuoso SPARQL query service implements the SPARQL Protocol for RDF (W3C Working Draft 25 January 2006) providing SPARQL query-processing for RDF data available on the open internet. The query service implementation extends the standard protocol by providing multiple output-formats alongside the standard XML results serialization. At present this uses additional query parameters, although content-negotiation will be supported soon.
