RDFa is a specification for attributes to express structured data in HTML5,
XHTML, and any XML application. The rendered, hypertext content of (X)HTML or
XML is reused by the RDFa markup, so that publishers don't need to repeat
significant data in the document. Tools can extract that structured data and
generate RDF triples for further reuse. RDFa can be considered as another
serialization format for RDF, alongside Turtle, RDF/XML, or JSON-LD
