An argo example

# For example

A document MYDOC is provided on an FTP site. The details of the site are stored in a forwarding document. The user starts with the UDI

    		http://argo.upenn.edu/1723576123

    or
    	dip{
    	  host:argo.upenn.edu
    	  token:1723576123
    	}

which it uses to access the argo server. The server returns a document containing the access details for the document itself:

    	ftp{
    	  host:asghd.sdf.edu
    	  port#21
    	  path:/pub/junk/dpc/x.ps
            }

This is simplified (and may be wrong - Tim) but shows the difference between the W3 model in which the server would return a pointer to the FTP document as another UDI, allowing the user to make links directly to

    	file://asghd.sdf.edu:21/pub/junk/dpc/x.ps
