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
