It's related to httpRange-14 [1], but I don't think it's quite the same thing. In my most recent attempt to name it, I called it "When Browsable and Unambiguous Collide" [2], although I don't love that name either. For RDF (where the syntax offers no support of distinguishing subject indicators), I recommend using either a HashURI [3] or a 303-redirect SlashURI [4]. -- sandro [1] http://www.w3.org/2001/tag/ilist#httpRange-14 [2] http://esw.w3.org/topic/WhenBrowsableAndUnambiguousCollide [3] http://esw.w3.org/topic/HashURI [4] http://esw.w3.org/topic/SlashURI
