PERSISTENT IDENTIFIERS:WHAT IF?

"What if we couldn't rely on an affordable PID system?"

"What a mess! What happened?"

"Don't worry, you can use PIDs!
PIDs can refer to all the information associated with a real object, including its location, or to any of its potential surrogates, e.g. digital images, a museum collection where it belongs, research documents referring to it and other services.
PIDs may be applied to real objects as well as to more abstract concepts like services, transformation issues, aggregation or disaggregation of objects and organizations."
