A wiki about XDI: http://wiki.oasis-open.org/xdi

He was showing us sections of http://www.oasis-open.org/committees/download.php/22078/xdi-rdfx-model-v1.pdf (this is also linked from the front page of the above wiki)

XDI is the marriage of XRI and RDF (Resource Description Framework) http://www.xdi.org/

XRI is an extensible way of addressing things, far more specifically than URLs/URIs http://www.oasis-open.org/committees/xri/ "identifiers that are location-, application-, and transport-independent"

RDF is a way of stating relationships among things. An RDF statement is composed of two items and a relationship between them. http://www.w3.org/RDF/

xri://=drummond is the XRI address of Drummond's i-name. The HTTP form of this address (called an HTTP XRI or HXRI) is http://xri.net/=drummond. The "xri.net" portion is the address of an HXRI proxy resolver. Anyone can run one at an xri.* domain.

Appending XRIs: you can combine them with '/' between element to create components Parens for grouping (a composite with several components are made into a single component.

A link contract is an XDI document that governs the sharing of other XDI documents. (i.e. permissions)

Real world examples:

When you put up a FOAF document, the whole things is either public or private. If you had the same data in XDI format and with the right software, it could make particular sets of data available to particular people or groups to view and/or edit.

Axil gives another use of letting people and groups share their purchasing history as something that other trusted people can browse through to help them make sustainable/ethical purchasing decisions.
