XDI.org is a non-profit public trust organization whose purpose is to provide public infrastructure for digital identity, security, and privacy using the open standard XDI semantic data interchange protocol developed by the OASIS XDI Technical Committee.
We are currently transitioning the XDI registry service used to register XDI identifiers (also called “i-names” and “i-numbers” or “cloud names” and “cloud numbers”). This service, formerly operated by Neustar under contract to XDI.org, is now being transitioned to XDI.org’s own operation. The transition required registration of new cloud names and cloud numbers to be temporarily halted, and also an interruption in resolution services for existing registrations by the current active registrars (1ID.com, FullXRI, and Respect Network).
If you have registered a cloud name and cloud number, be assured that your registration remains valid through this transition period even though it is not resolving. Registration of new cloud names and numbers should resume soon after the transition is complete. Note however that the old i-services (OpenID, Contact Page, and Forwarding) will no longer be supported, as these will be gradually be replaced by native XDI services.
The XDI.org registry has always been designed under the model of “minimum viable centralization”, with the registry’s primary role being to host a discoverable identifier that is bound to an XDI endpoint—a data repository that “speaks” the XDI protocol. The XDI endpoints themselves can be fully decentralized and hosted however the registrant chooses—for example:
- Self-hosted on a registrant’s own servers or devices.
- Hosted on a server in a co-location facility under the control of the registrant.
- Hosted by an XDI service provider of the registrant’s choice.
This model of decentralized XDI endpoints discoverable via a common registry service is the same model used by today’s global Internet SMTP email service. With XDI, this model will extend to peer-to-peer semantic data interchange between people, organizations and things.
Over the past few years, several new and innovative technologies have made it technically possible to decentralize even the registry component, i.e., the last piece of the puzzle. In keeping with the mandate of minimum viable centralization, the feedback of the XDI community has been strongly supportive of taking this step.
XDI.org has listened and its Board of Trustees has chartered the XDI Registry Working Group to design the next generation of the XDI registry so it will fully decentralized this function.This task force of industry experts is currently evaluating the available technologies and will recommend a plan for the new decentralized XDI registry in Q4 2015, with the goal of implementing this plan as soon as possible in 2016.
