Although I'm still working on a longer response to Greg's original question
("Why is XRI so obtuse?"), I wanted to make sure Greg's misconceptions that
"XRI is not free, not open, centralised, and has a financial barrier to
Entry" got answered right away:
1) XRI is an open, public, royalty-free identifier standard developed at
OASIS. It is every bit as free as the URI or IRI specifications from IETF
2) The use of XRI does NOT require the use of XRI global registry services.
Although such registries are supported by XRI architecture, they are only
one option. You can also use XRI infrastructure with a) DNS names, b) IP
addresses, or c) complete p2p identification and resolution as described by
XRI TC co-chair Gabe Wachob in his blog entry at
3) Only if a person or organization chooses to use the XRI global registry
services (GRS) offered by XDI.org (http://www.xdi.org) is there a
registration fee, exactly as there is in any publicly-registerable DNS
(Disclaimer: XDI.org contracts with Cordance (my employer) to provide such
registry services, and Cordance in turn subcontracts operation of these
registries to NeuStar (http://www.neustar.biz). NeuStar is best known for
running many of the global telephone number registries; they also runs the
DNS .biz and .us registries and the .cn and .tw gateways.)
4) Any registrant of a global i-name/i-number (an =name/=!number for
individuals or an @name/@!number for organizations) has the same ability to
delegate community i-names/i-numbers (*names or !numbers) as DNS name
registrants have to delegate .names. That means the vast majority of these
will in fact be free, just as third-level domains are often free. (The only
differences are the order of the segments, delimiters, and allowed
characters. DNS delegates right-to-left, supports only dots as delimiters,
and allows only ASCII characters and dashes. XRI delegates left-to-right,
supports both stars (*) and bangs (!) as delimiters, and permits the full
IRI range of Unicode characters plus dots and dashes.)
Net net: community i-names and i-numbers can be every bit as free and easily
available as DNS names. The challenge is that XRI infrastructure is less
than 1% as evolved as DNS infrastructure at this point, so unfortunately you
can't yet get everything from XRI i-brokers that you can get from GoDaddy at
the drop of a hat.
But we're working on it as fast as we can ;-)
