Linked Data

A paradigm for data interaction across the Web, based on four basic principles:

Use URIs as names for things

Use HTTP URIs so that people can look up

Provide useful information using the standards (RDF*, SPARQL)

Include links to more things

Proposed by Tim Berners-Lee in 2006

http://www.w3.org/DesignIssues/LinkedData.html

RDF

W3C Resource Description Framework

Directed labeled graphs

Triple-based data model(subject, predicate, object)

One model, several serializations:RDF/XML, Turtle, N3, JSON-LD, RDFa

Actually a whole technology stackRDFS, OWL, SPARQL, RIF

RDF: triples

RDF: identifiers

RDF: Linked Data

Linked Data Platform

Mission of producing a standard for HTTP-based (RESTful) application integration patterns using Read-Write Linked Data.

W3C Working Group started in June 20121st public working draft published in October

Planned for June 2014

Technology available according the W3C Patent Policy
