Semantic Web

The Semantic Web is an extension of the Web, designed so that data is easily machine-readable. Semantic Web technology is most prominently used for displaying summaries of webpages (e.g. social media previews and search engine results). A core concept of Semantic Web is Linked Data, where data is represented as a graph, and nodes are given universal identifiers. Linked Data can be used to store data about any concept in an unambiguous form.

The technology used for Linked Data is RDF (Resource Description Framework). It is a superset of standard link relations found on the Web. It extends the concept of link relationships to allow links to point to strings of data, in addition to a URI. For example, in the classic Web, a webpage might have a rel=author link pointing to the author's homepage. In RDF, the target may also be a date, number, label, or similar piece of data.
