> as you may know, RDFa 1.1 is in its finishing round (the editors' draft is available at [1]). One of the last issues that the group has to decide is how to interpret, when generating RDF, a statement like
> 
> <a rel="author" href="blabla">....</a>
> 
> ie, what RDF predicates should be generated (if any) for the value of @rel. RDFa 1.0 used the rel relations as defined in the XHTML document, and generated a predicate in the xhtml/vocab namespace, e.g.,
> 
> http://www.w3.org/1999/xhtml/vocab#author
> 
> for all @rel values that XHTML1 defined. For RDFa 1.1, the situation is a little bit complicated, because it is unclear what @rel relations the HTML WG will define for HTML5[2]. It will be different, probably, than the old list.
> 
> On our meeting today, the RDFa WG decided that, instead of any of the HTML specs, we should use the IANA link relation list:
> 
> http://www.iana.org/assignments/link-relations/link-relations.xml
> 
> which seems to be much more complete than what is in the current HTML document[2] anyway.
> 
> However, there are some details that we should clarify, hence this mail. These are:
> 
> 1. What is the authoritative URI to refer to for this list? Is the URI above all right? We must admit we simply got there via google:-)
> 
> 2. Does IANA have any advice/requirement as for the URI-s to be used when materializing those link relations in RDF? As I said, we used the xhtml/vocab namespace before, and we can certainly continue doing that for most, although the describedby relation already has a URI in the Powder namespace. Or, alternatively, do you guys have fixed URI-s that you'd prefer us to use?
> 
> 3. How frequently do you plan to update this list? 
> 
> I think that is it for now...
> 
> Thanks for your help an advice
