Hi John,

John said:
Fair enough.  But you can get a Persistent URL from purl.org, and
you don't even need to worry about mapping it.

Didier replies:
Yes you are right. The problem I have with PURL.org is that if the site
is off, the name resolver is dead. This leads to a system breakdown. If,
on the other hand, the URN name resolution based on DNS would took off,
even if a DNS server is off, the name resolution can still happen. This
is because DNS includes server redundancy and caching. Said differently
is more robust and scalable. Maybe DNS URN name resolution didn't
happened because Microsoft and IBM weren't behind it... with their huge
money pockets :0

Cheers
