 Status: ~~LASTMOD~~ Under development
+Persistent Identifiers (PIDs) are an important building block of any FAIR data ecosystem. There are numerous PID types existing for a variety of diverse, but also similar applications. As such it is difficult to decide, whic PID type to adopt. This decision process should use transparent technical, organisational and community-related criteria and processe. Where an established PID system exists for a particular entity type, this system should be used instead of locally defined identifiers or unstructured textual descriptions.
+This recommendation explains, what criteria can be employed to select PID types for particular applications.

 =====Recommendation ====
-[shortened from below]
+Helmholtz Earth and Environment data providers and operators of research information systems should use established, globally unique and resolvable PID types whenever metadata refers to an entity type for which a suitable PID system is available.
-[Format: Wer! macht was! wo! wann! unter welchen Voraussetzungen!]
+The PID system should be selected according to documented criteria concerning scope, community adoption, governance, sustainability, metadata, interoperability and technical operation.
