What is the primary purpose of XRI and XDI?
Together, XRI and XDI solve the twin problems of persistent identity and trusted data sharing relationships by providing the technical foundation for linking people and organizations in a “Web of trust” just the way the Web lets us link pages in a “Web of text”. XRIs (Extensible Resource Identifiers) address a longstanding problem on the Internet: how to have a persistent, portable, privacy-protected identifier for any resource, from a person to a company to an application to a concept. XDI (XRI Data Interchange) uses XRIs to securely and privately share, link, and synchronize data between any two devices, domains, or applications and maintain this link for as long as the two parties want to keep a data sharing relationship.
