What are the basics of Linked Data?

Linked Data

This powerful concept is about using hyperlinks (specifically, HTTP URIs) as entity identifiers.

Why the HTTP URI specificity?

This form of identifier has a built-in ability to deliver:

  1. Denotation
  2. Connotation

Thus, like the Web in general, every link resolves to a document – but in this case the document is an entity description document i.e., a data-sheet rather than a wordy document.

Examples:

  1. About: Datasheet – by simply leveraging the fragment identifier feature of HTTP, any hyperlink identifying a document (i.e., HTTP URL variant of URI) evolves into an HTTP URI

  2. Linked Data - OpenLink Software Community – does the same thing for this discussion topic i.e., Linked Data - OpenLink Software Community is the identifier while Linked Data - OpenLink Software Community is the document identifier

I’ll stop here for now. Post any questions if you need further clarity.
