LINKED DATA

What is Linked Data?

The term Linked Data refers to a set of best practices for publishing structured data on the Web. These principles have been coined by Tim Berners-Lee in the design issue note Linked Data. The principles are:

1. Use URIs as names for things
2. Use HTTP URIs so that people can look up those names.
3. When someone looks up a URI, provide useful information.
4. Include links to other URIs. so that they can discover more things.
   The idea behind these principles is on the one hand side, to use standards for the representation and the access to data on the Web. On the other hand, the principles propagate to set hyperlinks between data from different sources. These hyperlinks connect all Linked Data into a single global data graph, similar as the hyperlinks on the classic Web connect all HTML documents into a single global information space. Thus, LinkedData is to spreadsheets and databases what the Web of hypertext documents is to word processor files. The Linked Open Data cloud diagramms give an overview of the linked data sets that are available on the Web.
