How Do I Get Going? Download, install, and experience the power of coherent integration of disparate data sources, data access protocols, and data representation formats. In an nutshell, commence exploitation of powerful business intelligence, socially enhanced collaboration, data virtualization, and entity analytics without writing a line of code! Turn "Big Data" into exploitable "Smart Data" without compromise! © 2012 OpenLink Software, All rights reserved.

How Does Virtuoso Expose LOD Cloud Data To ODBC Clients? Creation of ODBC accessible SQL Views using SPASQL (SPARQL inside SQL) that targets local data Ditto via SPARQL-FED (Federated SPARQL) for external SPARQL endpoints. Example instances include:  DBpedia (Linked Data version of Wikipedia content and LOD Cloud nexus)  URIBurner Service for “on the fly” transformation of data from: LinkedIn, Facebook, Twitter, Google+, Freebase, Disqus etc.  Live Linked Open Data LOD Cloud Cache. © 2012 OpenLink Software, All rights reserved.

Demo Query ToolsMicrosoft Access (Windows)Filemaker (Mac OS X)Tibco SpotFire (Windows)Tableau Deskop (Windows)SAP Crystal Reports (Windows)HTML5 based ODBC Explorer (Browser) – requires local ODBCDriver ManagerHTML5 based XMLA Explorer (Browser) – no local ODBC DriverManager requiredVirtuoso ConductorVirtuoso iSQLAny other ODBC compliant tools that offers a SQL Query Editor. © 2012 OpenLink Software, All rights reserved.

Sample SPARQL EndpointsLive Virtuoso Demo Server – Focal Point (SPARQL andHTML5 XMLA-ODBC Client) for all live demos in this presentationDBpedia - Structured Data rendition of Wikipedia contentLinked Open Data Cloud Cache – majority of datasets published tothe LOD cloudURIBurner – Live Linked Data Transformation Service for Web Pages& Web 2.0 ServicesHealth.Data.Gov – U.S. Govt.

How It WorksConstruct or Locate SPARQL Query of interestVerify Query against its original SPARQL EndpointGo to a Virtuoso SPARQL endpoint and execute a FederatedSPARQL (SPARQL-FED) variant of queryUsing any ODBC compliant application, execute SPARQL pass-through queries by placing the pragma “SPARQL” before your Basic orFederated SPARQL query text. © 2012 OpenLink Software, All rights reserved.
