And that's just what it is.\n\nRDF is comprised of a Data Model (EAV/CR Graph) and Data Representation Formats such as: N3, Turtle, RDF/XML etc. \n\nRDF's essence is about: "Entities" and "Attributes" being URI based, while "Values" may be URI or Literals (typed or untyped) based. \n\nURIs are Entity Identifiers.\n\nWhat is Linked Data?\n\nShort for "Web of Linked Data" or "Linked Data Web".\nA term coined by TimBL that describes an HTTP based "data access by reference pattern" that uses a single pointer or handle for "referring to" and "obtaining actual data about" an entity.\nLinked Data uses the deceptively simple messaging scheme of HTTP to deliver a granular entity reference and access mechanism that transcends traditional computing boundaries such as: operating system, application, database engines, and networks.\n\nHow are Linked Data & RDF Related?\n\nLinked Data simply mandates the following re. RDF: \n\nURIs should be HTTP based so that you can "refer to" (Reference) an Entity, its Attributes, or URI based Attribute values via the Web (infact any HTTP based network e.g., Intranets and Extranets)\n\nURIs should also be HTTP based so that you can use them to de-reference resource descriptions via the Web (or Intranets and Extranets).\n\n\n\nNote: by Entity I am also referring to: a resource (Web parlance), data item, data object, real-world object, or datum. \n\nLinked Data is also about, using URIs and HTTP's content negotiation feature to separate: presentation, representation, access, and identity of data items. Even better, content negotiation can be driven by user agent and/or data server based quality of service algorithms (representation preference order schemes).\n\nTo conclude, Linked Data is ultimately about the realization that: Data is the new Electricity, and it's conductors are URIs :-)\n\nTip to governments of the world: we are in exponential times, the current downturn is but one side of the "exponential times ledger", the other side of the "exponential times ledger" is simply about unleashing "raw data" -- in structured form -- into the Web, so that "citizen analysts" can blossom and ultimately deliver the transparency desperately sought at every level of the economic value chain. Think: "raw data ready" whenever you ponder about "shovel ready" infrastructure projects!" ; atom:title "Simple Explanation of RDF and Linked Data Dynamics" . @prefix ns10: . sioc:has_creator ns10:this ; sioc:has_container . @prefix ns11: . sioc:links_to ns11:i . @prefix dbpedia: . sioc:links_to dbpedia:Entity-attribute-value_model , dbpedia:Linked_Data , , dbpedia:Giant_Global_Graph , dbpedia:Entity , dbpedia:Uniform_Resource_Identifier ; atom:source ; atom:author ns1:this ; atom:published "2009-04-24T20:59:08Z" ; atom:updated "2009-04-24T21:14:41Z" . @prefix opl: . opl:isDescribedUsing . ns10:this rdf:type sioc:User . @prefix rdf: . @prefix atom: . rdf:type atom:Entry . @prefix sioct: . rdf:type sioct:BlogPost . @prefix rdfs: . rdfs:label "Data 3.0 (a Manifesto for Platform Agnostic Structured Data) Update 5" . @prefix sioc: . sioc:links_to . rdf:type sioct:BlogPost , atom:Entry ; rdfs:label "Revisiting HTTP based Linked Data (Update 1 - Demo Video Links Added)" ; sioc:links_to . @prefix ns5: . @prefix foaf: . ns5:this rdf:type foaf:Person ; foaf:made . rdf:type atom:Feed , sioct:Weblog ; rdfs:label "kidehen@openlinksw.com's BLOG [127] description" ; sioc:container_of ; atom:entry ; atom:contains . rdf:type sioct:BlogPost , atom:Entry ; rdfs:label "Linked Data & Identity" ; sioc:links_to . rdf:type sioct:BlogPost , atom:Entry ; rdfs:label "Linked Data Rules Simplified" ; sioc:links_to . @prefix ns7: . ns7:this rdf:type sioc:User ; sioc:creator_of . rdf:type atom:Entry , sioct:BlogPost ; rdfs:label "Getting The Linked Data Value Pyramid Layers Right (Update #2)" ; sioc:links_to . rdf:type sioct:BlogPost , atom:Entry ; rdfs:label "Getting The Linked Data Value Pyramid Layers Right (Update #2)" ; sioc:links_to .
