What is Linked Data? ,[object Object],[object Object],[object Object]

Bridging the gap: Semantic Web – Web of Data Data Semantics Linking data entries using URIs powered by RDF and SPARQL helps to create Web applications and portals that use REST-based models, integrating data from multimple sources withouth need of preexisting schema Provide models that can be used to represent expressive semantic descriptions (OWL) of applications domains and provide inferencing power for Web and non-Web applications that need A knowledge base Scalability Linked Data Ontologies

The LOD Cloud Collectively, the data sets consist of over 4.5 billion RDF triples , which are interlinked by around 180 million RDF links (March 2009). Typically, a data set contains knowledge about a particular domain, like books, music, encyclopedic data, companies

Information Model (IDN-IM) Information Model (IDN-IM) Generic information modelled in IDN is formalized as an aggregation of elementary data units, named “primitive information units (P.I.U.s)” Primitive information units contain generic data and metadata NodeTypes embed the primitive information-unit schema defining the application-level properties contained in the node A primitive information unit is a node in a directed graph
