GRDDL is a technique for using XML/XHTML dialects (especially microformats) as custom RDF syntaxes by having each document point, directly or indirectly, to a transformation to an RDF graph. RDFa is a design for mixing RDF syntax into HTML. GRDDL accomodates a wider variety of dialects at the expense of asking consumers to execute potentially untrusted code. RDFa allows one parser to work for data from a variety of domains and provides a direct relationship between the RDF data and the HTML document structure, which provides better support for copy-and-paste.YesParser or ConverterXSLTNew2007-11-18<img src="./wp-content/themes/ai3/images/swtools_thumbnails/w3.orgca1d41a747ce60a80acb5baf69483ab3.jpg" />
