My human-name can be mapped to a telephone number. My human-name is not, however, a telephone number. An "identifier" can certainly be mapped to a network location with the aid of the appropriate database, just as a DNS name can be mapped to a network location. Maybe you're using the wrong word, and instead of "mapped" you really meant something like 'directly related', or something like that, but the problem is that that's a somewhat nebulous turn of phrase. Which is why I previously suggested that nice gold-standard, easily-comprehendable tests for 'does this name have location information embedded in it' are: - Do you have to get a new one when you move to a new location? - Given two location-based names, can you tell, by comparing *just the names*, whether they are 'close' to each other? Maybe someone else can come up with a snappy word/phrase which clearly, cleanly and concisely embodies that very close relationship... > A slightly different way to say it is that a locator is a handle for > a route. No. My street address is not a handle (in any simple sense) for directions to my house. Yes, with a lot of data (connectivity information), and a certain amount of computing, it can be turned into directions, but the relationship is not a simple one. This was all quite clear a long time ago; see IEN-19, John Shoch, "Inter-Network Naming, Addressing, and Routing", January 1978, now finally available at: ftp://ftp.isi.edu/in-notes/ien/ien19.txt Everyone here should be familiar with what it has to say.
