Sorry if I have missed something, but... We currently put things like <changefreq>monthly</changefreq> <changefreq>daily</changefreq> <changefreq>never</changefreq> in our semantic sitemaps, and these suggestions seem very similar. Eg http://dotac.rkbexplorer.com/sitemap.xml (And I think these frequencies may correspond to "normal" sitemaps.) So a naïve approach, if you want RDF, would be to use something very similar (and simple). Of course I am probably known for my naivity, which is often misplaced.
