[whatwg] Support for RDFa in HTML5

Tue Aug 2 06:55:37 PDT 2011

Hi,
according to the W3C Specification:
http://www.w3.org/TR/rdfa-in-html/

1. the xmlns attribute has been replaced with the prefix attribute

example: <html prefix="rdfa: http://www.w3.org/ns/rdfa#"<http://www.w3.org/ns/rdfa#%22>>

2. the RDFa declaration must be defined with the version attribute

example: <html version="HTML+RDFa 1.1">

Complete example:
<html version="HTML+RDFa 1.1" prefix="rdfa: http://www.w3.org/ns/rdfa#"<http://www.w3.org/ns/rdfa#%22>>

But both attributes are not supported in HTML5.
I would like to know if these attributes will be part of HTML5 or is there another valid method to integrate RDFa into HTML5?

Kind Regards
Aykut
