Resource Description Framework
RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed.
Notes: RDF does not assume that a namespace URI identifies a retrievable Web resource, see RDF primer.
