Manu,

though I am back home, and begin to look at some of my mails, I would still send my regrets for this. I am not yet in shape to do that:-( 

Sorry about that

Just giving my immediate reactions to the issues, though, see below

I am not sure what we can do about this, beyond warning users that this is what happens...

My impression is that the issue title has become a misnomer, and the solution put forward is that RDFa HTML should not have the extra rule on an implicit empty @about on <head> and <body>. The default @about on the top level element, ie, <html> is fine and disallowing an explicit @about there becomes unnecessary... I would be happy to go along such a change.

I am not convinced that the use cases warrant an additional level of complication in the RDFa definition. I would prefer not to take this.

I am not convinced that the use cases warrant an additional level of complication in the RDFa definition. I would prefer not to take this.


> 5. ISSUE-123: HTML Literals
>   *https://www.w3.org/2010/02/rdfa/track/issues/123

Defining a new literal is not an easy matter. The RDF WG is currently discussion the issues and possible changes on the XML literal datatype and the HTML Datatype is also an open issue for the RDF WG. Let them do that.

I think that, for RDFa, the only thing we can do is to add a note to the document referring to the fact that this is under discussion at the RDF WG and saying something like if an HTML Datatype is defined, RDFa processors in the future might understand that datatype and may process it similarly to the XML Datatype, ie, putting out the subtree verbatim. 

That being said, it may not always be easy. In my case, the HTML5 Parser produces a DOM tree and, in that DOM tree, what I see is not the HTML content textually, but the DOM information instead. When generating a literal I would actually produce an XML Literal, not an HTML Literal; I am not even sure how I could produce the original textual content...

Cheers

Ivan
