W3C Opens Data on the Web with SPARQL
Powerful Technology for Querying Distributed and Diverse Data	

   http://www.w3.org/ -- 15 January 2008 -- W3C announced today
   the publication of SPARQL, the key standard for opening up
   data on the Semantic Web. With SPARQL query technology,
   pronounced "sparkle," people can focus on what they want to
   know rather than on the database technology or data format
   used behind the scenes to store the data. Because SPARQL
   queries express high-level goals, it is easier to extend them
   to unanticipated data sources, or even to port them to new
   applications.

   "Trying to use the Semantic Web without SPARQL is like trying
   to use a relational database without SQL," explained Tim
   Berners-Lee, W3C Director. "SPARQL makes it possible to query
   information from databases and other diverse sources in the
   wild, across the Web."

   http://www.w3.org/ -- 15 January 2008 -- W3C announced today
   the publication of SPARQL, the key standard for opening up
   data on the Semantic Web. With SPARQL query technology,
   pronounced "sparkle," people can focus on what they want to
   know rather than on the database technology or data format
   used behind the scenes to store the data. Because SPARQL
   queries express high-level goals, it is easier to extend them
   to unanticipated data sources, or even to port them to new
   applications.

   "Trying to use the Semantic Web without SPARQL is like trying
   to use a relational database without SQL," explained Tim
   Berners-Lee, W3C Director. "SPARQL makes it possible to query
   information from databases and other diverse sources in the
   wild, across the Web."

   There are already 14 known implementations of SPARQL, many of
   which are open source.

  SPARQL Overcomes Traditional Query Language Limitations of
  Local Searches, Single Formats

   Many successful query languages exist, including standards
   such as SQL and XQuery. These were primarily designed for
   queries limited to a single product, format, type of
   information, or local data store.  Traditionally, it has been
   necessary to formulate the same high-level query differently
   depending on application or the specific arrangement chosen
   for the relational database. And when querying multiple data
   sources it has been necessary to write logic to merge the
   results. These limitations have imposed higher developer costs
   and created barriers to incorporating new data sources.

   The goal of the Semantic Web is to enable people to share,
   merge, and reuse data globally. SPARQL is designed for use at
   the scale of the Web, and thus enables queries over
   distributed data sources, independent of format. Creating a
   single query across diverse data stores is easier than having
   to create multiple queries; it also costs less and provides
   richer results.

   Because SPARQL has no tie to a specific database format, it
   can be used to take advantage of the tidal wave of Web 2.0
   data and mash it up with other Semantic Web
   resources. Furthermore, because disparate data sources may not
   have the same 'shape' or share the same properties, SPARQL is
   designed to query non-uniform data.

  SPARQL Turns Data Access into a Web Service

   The combination of the SPARQL query language and protocol
   creates a Web service in its purest sense; running on top of
   HTTP or SOAP, it provides a standard Web service for anything
   which asks a question.

   "SPARQL's focus on querying the data models saves time for
   developers; there's no need for a host of little Web services
   to retrieve different aspects of the state of a system,"
   explained Lee Feigenbaum, Chair of the RDF Data Access Working
   Group. "This allows the user of the SPARQL endpoint to ask any
   question -- it is as though they could design their own
   interface instead of having to work with a limited set of
   fixed services."

   The SPARQL specification defines a query language and a
   protocol and works with the other core Semantic Web
   technologies from W3C: Resource Description Framework (RDF)
   for representing data; RDF Schema; Web Ontology Language (OWL)
   for building vocabularies; and Gleaning Resource Descriptions
   from Dialects of Languages (GRDDL), for automatically
   extracting Semantic Web data from documents. SPARQL also makes
   use of other W3C standards found in Web services
   implementations, such as Web Services Description Language
   (WSDL).

  W3C's Data Access Working Group Includes Industry Leaders in
  Database Technology, Web Applications

   W3C RDF Data Access Working Group produced the three SPARQL
   Recommendations issued today: the SPARQL Query Language for
   RDF, The SPARQL Protocol for RDF, and the SPARQL Query Results
   XML Format. The Working Group includes invited experts and
   participants from Agfa-Gevaert N. V.; Asemantics S.R.L.; Clark
   & Parsia LLC; Cleveland Clinic; Eindhoven University of
   Technology; Free University of Bozen-Bolzano; Garlik; HP; IBM
   Corporation; Matsushita Electric Industrial Co., Ltd. (MEI);
   Nippon Telegraph & Telephone Corp. (NTT); OpenLink Software;
   Oracle; and Profium, Ltd.  The SPARQL Testimonials page
   contains statements of support and commitments to implement
   the new Recommendations.

   W3C continues to enhance the relationship between the Semantic
   Web and traditional databases; see the report from the W3C
   Workshop on RDF Access to Relational Databases from October
   2007.

Asemantics

  Asemantics S.r.l., the European Semantic Web company has been
  actively contributing to the W3C DAWG standardization process
  and successfully deploying W3C's SPARQL query language and
  protocol based real-world solutions inside public and private
  sector; for the European Space Agency (ESA/ESRIN) we
  successfully built ad-hoc dynamic satellite image galleries and
  an EO interoperability catalog search engine using the
  SPARQL. We worked together with Rijkswaterstaat (the Dutch
  Water Authority) to create an RDF based library of national
  water measurement data about more than four centuries of
  different physical and biological measurements related to sea,
  coastal and inland water; catalog and detailed search are
  internally being performed using SPARQL. Inside the Joost
  venture we successfully used RDF related technologies including
  the SPARQL query and language and protocol to build dynamic and
  flexible digital asset management tools to bridge content
  owners, metadata engineering and management related
  workflows. We are working together with the British
  Broadcasting Corporation (BBC) to build a next generation feed
  aggregator inside the Memoryshare initiative which internally
  stores information in RDF in order to preserve all richness of
  the original information and all relations among the data;
  which is then being queried dynamically using the SPARQL query
  language.

  Asemantics see SPARQL as a major W3C contribution which will
  enable next generation Internet semantic applications in the
  mainstream.


 -- Alberto Reggiori, CTO Asemantics S.r.l.

  data from the Semantic Web. INRIA teams have invested efforts in
  implementing the Recommendation and deliver right away
  SPARQL-compliant tools. The CORESE search engine for the
  semantic web can evaluate SPARQL queries against RDF, OWL and rule
  content. We also developed PSPARQL: a query language which can
  express all SPARQL queries as well as extensions with path
  expressions allowing more general queries. A PSPARQL query engine
  is also available.

   -- Pierre Paradinas, Head of Technological Development, INRIA

OpenLink Software

  SPARQL bridges the gap between the vision and the manifestation
  of a Web of semantically interlinked data (Linked Data). This
  powerful mechanism helps expose and explain the data
  integration prowess of our Virtuoso Universal Server and
  OpenLink Data Spaces products, across all levels of the
  Internet, Intranet, and Extranet.

  By leveraging Web architecture in devising this standard --
  comprised of an open query language, communications protocol,
  and results serialization format -- the W3C has ingeniously
  delivered an unobtrusive bridge between the current Web of
  Documents and the emerging Web of Linked Data. SPARQL will
  ultimately enhance the value of the Web for everyone.

  -- Kingsley Idehen, President & CEO, OpenLink Software
