What do we want from data?

Findable – Easy to find by both humans and computer systems Metadata

Accessible – Stored for long term, accessed and/or downloaded with well-defined license and access

Interoperable – Ready to be combined with other datasets by humans as well as computer systems;

Reusable – Ready to be used for future research and to be processed further using computational methods.

What do we know about Persistent Identifiers?

A Persistent Identifier, also known as PID, is an identifier that is effectively permanently assigned to a resource.

identifier resource location

a permanent name or identity

although it may change over time

1. points to a resource(s) 2. globally unique3. PID is persistent over time

PID Training

Use persistent identifier for your data

Managing data online, includes managing the persistent identifier (PID) for the data.

Synchronize PID, Data during creation, maintenance, update and deletion of your data!

PID should always be updated to point to the new location (URL). continue to provide the latest information about the resource.

PID Training

What do you actually need ?

a PID service, that offers an API for creating and managing PIDs

EUDAT has adopted Handle-based persistent identifiers

Some EUDAT services require integration of Handle in your infrastructure

EUDAT offers a a service dedicated to provide, resolve and mint persistent identifiers (PID) supported by the ePIC consortium.

PID Training

The Basics of ePIC

ePIC was founded in 2009 by a consortium of European partners in order to provide PID services for the European Research Community, based on the handle system. ePIC:

targets mainly at data management of individual resources allowing association of extra data with the PID: checksum, link to flexible metadata, …is only a steward for the PIDs, no lock-inis totally compatible with the DOI system, and a PID (including the prefix) can also be interpreted from any DOI serverdoes not tie you in to a domain-specific, esoteric technology  but gives you access to a global identifier, interchangeable with others of this type
