Does anyone know the process for registering a sub-scheme for info: uris? I'd like to have one for SuDoc classification numbers, info:sudoc/. I'm not sure if I can register that on my own, without working with the US Government Printing Office, who actually maintains sudocs. But if I have to get GPO to do it, I'll probably give up quicker (unless it turns out easier than I thought to find the right person at GPO and get them to sign on -- I doubt it!). Or if the registration process is really long and onerous. But if it's easy enough to just fill out a form and get info:sudoc registered, I'd rather it be legal than use things that look like an info uri but really aren't a legally registered sub-scheme. Anyone know? Jonathan
