It comes mostly from the decentralized ID work and social web work.
It's main uptake is in the Infocard domain, of which the most working
software seems to be Project Nori [1]. The W3C TAG thought that XRIs
could be reduced to URIs [2] but hasn't looked at XDI to my knowledge.
There are also some questions re XRIs, as an early version of them
were patented and this led to
the W3C Royalty Free Patent Policy being formed [3], but the XRI folks
like Drummond Reed seem to have been working on correcting this. The
current state of play I'm not sure about it.
