Another way other than @profile, @vocab or @map

Hello all,

I have been very interested with your discussions on the uses of 
@profile, @vocab and more recently @map and to truthful I think the 
conversations have gone a bit wild.

It occurred to me that really the simplest problem should be solved 
first "how to allow un prefixed property names in RDFa".

I dont believe an author should be required to create another level of 
indirection by either having to create profile documents in RDFa, JSON, 
maybe even XSLT because this  kind of indirection has failed already in 
the market place (I believe) in favour of well named un-prefixed tokens 
such as those found in microformats and microdata.

Much as I personally like the Idea of resurrecting the @profile 
attribute, I believe that horse has bolted and you may have difficulty 
persuading the html5-wg that its a good idea, but you never know :)

With all the above in mind,  RDFa could I think re-use an attribute name 
that already exists in htm5, microdata to be more precise "itemtype"[1]. 
RDFa could be used pretty much like microdata eg:

<div itemtype="http://www.w3.org/2006/vcard/ns#" about="#BusinessEntity" 
<div property="fn">L'Amourita Pizza</div>
<div rel="adr">
<div typeof="Address">
<span property="street-address">2040 Any Street</span>,
<span property="locality">Springfield</span>,
<span property="postal-code">98102</span>.
              Tel: <span property="tel">206-555-7242</span>.
<span rel="url" resource="http://pizza.example.com/"></span>

The re-use of "itemtype" from microdata in this way would make it easy 
for RDFa authors to understand what the attribute is used for because it 
will be well documented for use in both RDFa and HTML, It will also 
reduce clashing semantics and repetition of data.

Best wishes.
