Questions tagged [triples]

A triple is an assertion of the form subject-predicate-object, for example [JohnSmith-brotherOf-JaneSmith], and [JaneSmith-hasAge-"34"]. Assertions (binary relations) of this type form the basis of the Semantic Web languages RDF and OWL. Triples can be interlinked if the object of one triple is the subject of another. Databases designed to manage such assertions are often called triplestores.
