Linked Data is about enabling computers to search structured information about “things” over the web. The linking methodology is based on the following Semantic Web principles:
1) Things are uniquely identified using Uniform Resource Identifiers (URIs).
2) Use HTTP (HyperText Transfer Protocol) URIs, to make those things accessible by computer programs.
3) The knowledge of things is expressed using the W3C Resource Description Framework (RDF) and queried via SPARQL.
