What are i-names and i-numbers?
An i-name is a human-friendly XRI intended for everyday use in browers, email clients, Web pages – anyplace a Web address (URI) would appear today. Unlike traditional Web addresses, i-names are designed to be very long-lived. For example, a personal i-name might last for a lifetime and never need to change no matter how often a person moved, changed jobs, changed service providers, etc. However, an i-name can (like a domain name) be transfered between registrants. An i-number is a special type of XRI that differs from an i-number in one critical way: once assigned to a resource, it is *never* reassigned. For this reason i-numbers are typically numbers and punctuation characters (similar to an IP address) and are thus much harder for humans to use.
