Which standard model is used for data interchange on web ?
Answer: A
The standard model for data interchange on the web is RDF.
The Resource Description Framework is the W3C standard for describing resources and exchanging data on the web. It expresses information as triples, subject, predicate and object, each identified by a URI, so data from different sources can be merged even when their schemas differ. It is the foundation of linked data and the semantic web.
RDF Schema (RDFS) is a vocabulary for defining classes and properties on top of RDF, not the interchange model itself. 'RDF : W' and 'RDF : D' do not exist as standards.
