Re: RDF Update Feeds

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.
Best
Hugh
