Semantic Sitemaps are a minimalist extension of Google's Sitemap protocol [1], which is XML-based, and not RDF. So at the moment we don't define RDFS classes. Once our basic spec is finalized, we will look into making a matching RDF vocabulary and GRDDL transform. This would be nice because of RDF's natural extensibility, and there would be natural synergies with POWDER. This vocabulary would of course include a class for SPARQL endpoints.
