If purl comes back up we are lucky, but maybe we could learn something
anyway.

Having names for fundamental terms based on the DNS system is a
weakness. What will we do if purl.org gets taken over by a casino site?
Will we argue that the terms keep their meaning even if the casino site
says something else? In my scifi post[1] I've scheduled this topic for
2015. Using hash-uri or other non-http uris have advantage of stability,
but it's harder to look up the meaning, could we combine the approaches?
should we have protocol independents terms with evolving meaning as in
natural languages?
