New Research Tool: Introducing the PID (Persistent Identifier) Services Registry

From the DataCite Blog:

We are pleased to announce the launch of the new persistent identifier (PID) services registry available at, a new service to find services built upon different PIDs from core technology providers and those who integrate from across a variety of disciplinary areas.


The PID Services Registry provides an easy way to look up existing PID services. To ensure persistence and discoverability of the services, services are registered with a DOI and DOI metadata (using the resourceTypeGeneral “Service”), and are thus backed by existing DOI infrastructure. This means that we can reuse a lot of the metadata fields defined for DataCite DOIs, e.g. identifiers for the organizations providing the PID services or funding. It also means that we can reuse the established federated DOI infrastructure for registration and distribution of metadata. One challenge we encountered is that DOI metadata are for the most part rather generic and some of the more specific information needed to describe PID services can currently not be included. We will work with the community to address this.

The interface provides searching and filtering of the registered services and this is presented using a modern React web application built upon our DataCite GraphQL API. The services were put together by various organizational partners across disciplines, 35 currently registered and we would like to continue growing this.
