Editing Topic map (section)

==RDF relationship==
Some work has been undertaken to provide interoperability between the W3C's [[Resource Description Framework|RDF]]/[[Web Ontology Language|OWL]]/[[SPARQL]] family of [[semantic web]] standards and the [[International Organization for Standardization|ISO]]'s family of ''Topic Maps'' standards though the two have slightly different goals.{{Citation needed|reason=What work?

The semantic [[expressive power (computer science)|expressive power]] of Topic Maps is, in many ways, equivalent to that of [[Resource Description Framework|RDF]],{{CN|date=March 2023}} but the major differences are that Topic Maps (i) provide a higher level of [[Semantic data model|semantic abstraction]] (providing a template of topics, associations and occurrences, while RDF only provides a template of two arguments linked by one relationship) and (hence) (ii) allow [[arity|''n''-ary]] relationships ([[hypergraph]]s) between any number of nodes, while RDF is limited to [[tuple|triplet]]s.{{CN|date=March 2023}}
