The group is sponsored by Oracle, HP, PartnersHealth, and " id="link-id175ed3a8">OpenLink Software.\nGoals\nThe goal of this effort is standardization of approaches (syntax and methodology) for mapping Relational Data Model instance data to RDF (Graph Data Model).\nBenefits\nEvery record in a relational table/view/stored procedure (Table Valued Functions/Procedures) is declaratively morphed into an Entity (instance of a Class associated with a Schema/Ontology). The derived entities become part of a graph that exposes relationships and relationship traversal paths that have lower JOIN Costs than attempting the same thing directly via SQL. In a nutshell, you end up with a conceptual interface atop a logical data layer that enables a much more productive mechanism for exploring homogeneous and/or heterogeneous data without confinement at the DB instance, SQL DBMS type, host operating system, local area network, or wide area network levels.\nJust as we have to mesh the Linked Data and Document Webs, unobtrusively. It's also important that the same principles to apply to exposure of RDBMS hosted data as RDF based Linked Data.\nWe all know that a large amount of data driving the IT engines of most enterprises resides in Relational Databases. And contrary to recent RDBMS vs RDF database misunderstandings espoused (hopefully inadvertently) by some commentators, Relational Database engines aren't going away anytime soon. Meshing Relational (logical) and Graph (conceptual) data models a natural progression along an evolutionary path towards: Analysis for All. By the way, there is a parallel evolution occurring in others realms such as Microsoft's ADO.NET's Entity Framework.\nHow would I use RDB2RDF Mapping?\nTo Unobtrusively expose existing data sources as RDF Linked Data. The links that follow provide examples:\n-- Enterprise Databases e.g. Northwind SQL Database as Linked Data (Zitgist View, OpenLink RDF Browser View, DISCO Browser View, Tabulator View)\n-- Content Management e.g. Drupal hosted Blog Posts as Linked Data\n\n-- Weblog Platform e.g. Wordpress hosted Blog Posts as Linked Data\n\n-- Wiki Platform e.g. MediaWiki hosted Wikiwords as Linked Data\n \nRelated\n\nVirtuoso's Meta Schema Language for Declaratively generating RDF Views of SQL Data (Presentation, White Paper, Tutorial, and Online Docs)\nESW Wiki's Collection of SQL-RDF Mapping Tools\n\n\n What the Semantic Web means for your Business \n\n\n\n\n" ; atom:title "New W3C Incubator Group: Relational Database to RDF Mapping" . @prefix ns10: . sioc:has_creator ns10:this ; sioc:has_container . @prefix dbpedia: . sioc:links_to dbpedia:Hewlett-Packard , dbpedia:Oracle_Corporation . @prefix ns12: . sioc:links_to ns12:ALFKI , . @prefix ns13: . sioc:links_to ns13:KingsleyIdehen . @prefix ns14: . sioc:links_to ns14:demo , dbpedia:Relational_database . @prefix ns15: . sioc:links_to ns15:demo , , , dbpedia:Drupal . @prefix ns16: . sioc:links_to ns16:this , dbpedia:MediaWiki , , , , , dbpedia:WordPress . @prefix ns17: . sioc:links_to ns17:ALFKI , . @prefix ns18: . sioc:links_to ns18:RdfAndSql , , , ; atom:source ; atom:author ns1:this ; atom:published "2008-03-05T17:13:35Z" ; atom:updated "2008-03-11T17:58:24Z" . @prefix opl: . opl:isDescribedUsing . ns10:this rdf:type sioc:User . @prefix rdf: . @prefix ns1: . @prefix foaf: . ns1:this rdf:type foaf:Person ; foaf:made . @prefix atom: . rdf:type atom:Feed . @prefix sioct: . rdf:type sioct:Weblog . @prefix rdfs: . rdfs:label "kidehen@openlinksw.com's BLOG [127] description" . @prefix sioc: . sioc:container_of ; atom:entry ; atom:contains . @prefix ns7: . ns7:this rdf:type sioc:User ; sioc:creator_of .
