description: '[PID4NFDI](https://pid.services.base4nfdi.de) is a Base4NFDI service
  that provides documentation about a small number of well-known identifier schemes
  (e.g., DOI) and services for registering identifiers within them (e.g., DataCite).
  This collection reflects their [PID Providers](https://pid.services.base4nfdi.de/get-pid/providers/)
  page. This comes with the following caveats:


  - Crossref and DataCite are services that mint DOIs. Since DOIs are the identifier
  space, only `doi` appears in this collection.

  - ePIC is a service that mints Handle system. Since Handles are the identifier space,
  only `hdl` appears in this collection

  - PIDINST is an abstraction on top of DataCite / ePIC, which is covered by `doi`
  and `hdl` as described above'
