A '''Uniform Resource Identifier''' ('''URI'''), formerly '''Universal Resource Identifier''', is a unique sequence of characters that identifies an abstract or physical resource,{{Sfn|Berners-Lee, Tim; Fielding, Roy T.; Masinter, Larry|2005|p=1|ps=, "Abstract"}} such as resources on a webpage, mail address, phone number,{{Sfn|Berners-Lee, Tim; Fielding, Roy T.; Masinter, Larry|2005|p=7|ps=; "1.1.2. Examples", "1.1.3. URI, URL, and URN"}} books, real-world objects such as people and places, concepts.{{Sfn|Berners-Lee, Tim; Fielding, Roy T.; Masinter, Larry|2005|p=5|ps=, "Resource: the term "resource" is used in a general sense for whatever might be identified by a URI"}} URIs are used to identify anything described using the [[Resource Description Framework]] (RDF), for example, concepts that are part of an [[Ontology (information science)|ontology]] defined using the [[Web Ontology Language]] (OWL), and people who are described using the [[FOAF (ontology)|Friend of a Friend vocabulary]] would each have an individual URI.
