What is a personalised persistent identifier (PID)?
Persistent or permanent author identifiers (PIDs) collect a researcher's publications and make them searchable by author without the risk of confusion with other researchers. The person in question may change their name, have the same name as someone else, or change institutions, organisations or universities - the permanent identifier remains.
For individuals, PID falls into the category of personal identifiers, i.e., a piece of information or data that can identify a unique person.
There are different models for personal identifiers. The publication database DiVA supports two variants of personal identifiers: ORCID and Umu-id.
