XDI
XDI (XRI Data Interchange) is a universal and expandable service for exchanging, linking and synchronizing data over the Internet and other networks using XML documents and XRIs (Extensible Resource Identifiers). The XDI protocol is being developed by the OASIS Technical Committee for XDI.
The goal of XDI is to identify, describe, link and synchronize data from any source in order to create an active, machine-readable data web , in the same way that content from any source forms the human-readable web today. In addition to a simple XML format for identifying and describing data, XDI uses so-called link contracts (connection agreements ), which make it possible to express ownership, security, data protection and rights over distributed data in a standardized machine-readable format.
This approach to a globally distributed data network is based on conventional mechanisms such as social rules and legally binding contracts that guarantee the functioning of organizations and societies. XDI can therefore play a role as an important component of the social web . XDI can also support the new legal concept of "virtual rights", which are based on the idea of a "virtual identity" and a fundamental right: "to have or not to have a virtual identity".
The international non-profit organization XDI.ORG develops services based on XRI and XDI.
