What is a personalised persistent identifier (PID)?
Persistent or permanent author identifiers (PIDs) compile a researcher's publications, making them searchable by the author without the risk of confusion with other researchers. Even though individuals may change their name, have the same name as someone else, or change institutions, organisations or universities, the permanent identifier remains consistent.
For individuals, PID falls within 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.
