What are some other ways of embedding semantic data in web pages?
Microformats are a technique for embedding semantic data in the CSS styles of an HTML document. It is not an RDF syntax, but conversions exist. RDFa is a way to embed RDF data in the CSS styles of an HTML document. The semantic information is spread throughout the HTML. GRDDL is a way for web sites to provide XSLT stylesheets to convert their XHTML pages to RDF format. Data can also be stored in an HTML document in the form of JSON, XML, or other formats. There are no standard conversions of such data to semantic web formats, though custom conversions are often possible.
