OK, it's badly named, but properties in RDF are URIs, and URIs are opaque. Let's imagine an agent which takes the RDFa of a page, and also adds some extra triples along the lines of: <page> sioc:links_to <dest> . For every <a href> and <link href> link on the page. It's reasonable to run the following SPARQL on that data: CONSTRUCT { ?author ex:endorses ?page . } WHERE { ?source dc:creator ?author . ?source sioc:links_to ?page . FILTER NOT EXISTS { ?source xhv:nofollow ?page . } } Personally for HTML5+RDFa I just accept the union of HTML5's rel values, and RDFa's rel values. -- Toby A Inkster <mailto:mail@tobyinkster.co.uk> <http://tobyinkster.co.uk>
