PERSISTENT IDENTIFIERS:WHAT IF?

"A PID is a label associated with something in a particular environment. On the Internet it should be globally unique, but it may only be so within a specified context. At any rate, it must be unique within the institution's own system."
"Oohhh, what a masterpiece!"

Therefore:
• Organisations should be clear, and make public, in which environment their PIDs are unique. Persistent Identifiers (PIDs): recommendations for institutions (PDF) by Gordon McKenna and Roxanne Wyns.
