RDF/XML

Filename extension	`.rdf`
Internet media type	`application/rdf+xml`
Developed by	World Wide Web Consortium
Type of format	Semantic Web
Container for	RDF data
Extended from	XML
Standard	Specification

RDF/XML is a syntax,^[1] defined by the W3C,^[2] to express (i.e. serialize) an RDF graph as an XML document. RDF/XML is sometimes misleadingly called simply RDF because it was introduced among the other W3C specifications defining RDF and it was historically the first W3C standard RDF serialization format. Although the RDF/XML format is still in use, other RDF serializations are now preferred by many RDF users, both because they are more human-friendly,^[3] and because some RDF graphs are not representable in RDF/XML due to restrictions on the syntax of XML QNames.
