A semantic network can be described as a layer structure. we have a URI in the button layer, which is a unique data identifier. and then we sit syntax like: xml, ns and xml xmls Next is a way to interpret semantic data: RDF and higher RDF, we have RDF, and OWL is not dependent on RDF? but is OWL, Dublin Core, and FOAF a kind of RDFa? What is the structure between them?
Dublin Core and FOAF are diagrams, that is, dictionaries that you can use to mark up your data.
OWL ( RDFS) - //. OWL RDFS RDF.
RDFa - RDF ( - RDF/XML Turtle).
