If you mean by xrd:alias

http://docs.oasis-open.org/xri/xrd/v1.0/os/xrd-1.0-os.html#element.alias

I like it alot.  I has also been talked about in w3c linked data circles
for a while, together with "canonical" (which could also be useful)

https://lists.w3.org/Archives/Public/semantic-web/2016May/0086.html

"An x:alias predicate which asserts that one name (IRI) is an alias of
another name (IRI) would be very useful. <a#b> x:alias <c#d> .

An x:canonical predicate which asserts <a#b> x:alias <c#d> . and that <a#b>
is the preferred IRI more useful still."
