Re: URI for abstract concepts (domain, host, origin, site, etc.)

the URI scheme specifies the protocol that has to be used the resource. 
how can that have nothing to do with the protocol?

that's HTTP and HTTPS, but probably not many other protocols. if you use 
mailto: or tel: or fax: or sms:, then there are other modes of 
interaction with the identified resource, and for those interactions 
there is no concept of a media type. and even for ftp:, there is no 
media type info; you can guess, but there is no protocol mechanism that 
supports it. so it really seems to me you're focusing on HTTP URIs which 
is fine; i just wanted to find out.
