Yes I agree with John. Most likely the URI will eventually stop
working, even if you use purl.org. In which case it's worst because
you don't even control the DNS. A better option would be to adopt
something like Trusty URIs:

Although more complicated. But it's an idea if we want to take URI
management more seriously.

Best,
Luca
