Persistent Identifier (PID)

Your Requirement

You want to get permanent references to your research data by Persistent Identifier (PIDs) to enable the refindability and long term accessability of the data in the case of sharing data with other researchers or citing data resources as basis of a publication.

Our Offer

We provide a PID service includings prefixes for you, where you can mint and maintain your PID via GUI or REST interface. We run the local resolver and provide as partner in the ePIC consortium access to at least two additional mirror servers, located somewhere else in Europe, to ensure the resolvability of the PIDs with high availibility. If your PID contains all required metadata required by DataCite, also a DOI can be derived from it.

Preconditions For Use

We offer quick access to the creation of individual PIDs in our self-service area. There you have the possibility to create, edit and display a list of your PID via the browser. If you need a larger amount of PIDs or would like to integrate the generation into your application, contact us.

All institutes and customers can use this service. All data resources that shall get a PID need to have a valid URL, such that a resolution is possible. For institutes it is advisable to consult with GWDG to require a dedicated prefix in order to align requirements and service configuration.

How To Use

Your Advantages

  • Your data becomes referable inside research groups and scientific communities and citable in scientific publications.
  • You are able to adjust yourself the URL of the data resource in case there are changes in the data location.
  • Institutes can use a dedicated prefix for the PID.
  • As data manager you can enforce policies for the PID management inside of your institution.
  • With the PID provided it is possible to assign a link to the metadata of the data resource as a parameter of the PID, and this way to enforce a strong coupling between data and metadata.
