Embedded RDF
Encyclopedia
Embedded RDF is a syntax for writing HTML
in such a way that the information in the HTML document can be extracted (with an eRDF parser or XSLT
stylesheet) into Resource Description Framework
. This can be of great use for searching within data.
It was invented by Ian Davis in 2005, and partly inspired by microformats
, a simplified approach to semantically annotate data in websites.
