The first draft of ROR (Resources of a Resource) is available at http://www.rorweb.com. ROR is simple vocabulary for describing the resources of a resource (a website, a blog, a feed, a list of things, a tree or web structure, etc) in a generic fashion. It also provides terms for describing objects commonly found on websites (products, articles, feeds, newsletters, methods, sitemaps, menus, reviews, etc).
