Persistent memory

Keeping track of all of this data is also a real challenge. One solution that has been suggested is for every piece of data to have its own PID – persistent identifier – to keep track of data as it is moved around and merged with other datasets. This would work in a similar way to how computers connected to the internet all have a unique IP address. Peter Wittenberg, scientific coordinator for the EUDAT project, explains:
“During the early internet it became obvious that there are cross-disciplinary common services that could be used by all research disciplines. The same email system could be used by physics and humanities researchers, for example. In the same way, we’re realising now that there are common components – building blocks – for global data infrastructures. One crucial building block we’re working on is a world-wide registration and resolution system for persistent identifiers. Every single piece of data would have a PID, just as computers connected to the internet have a unique IP address.”
