+====1. Explanation of the Background and Benefits of the Recommendation ====
+__About__
+Defintion of PIDs
+  * A persistent identifier (PI or PID) is a long-lasting reference to a document, file, web page, or other object (from Wikipedia).
+  * PID registers typically store core metadata with the PID
+  * PIDs are used in data infrastructures to link to common information
+  * Harmonizing the use of PIDs may improve interoperability of datasets between data repositories
+Criteria for the evaluation of PID Systems
+  - PID is globally unambiguously registerable
+  - PIDs are widely used, e.g. recommended by national and international organizations
+  - PID registrar has a transparent governance
+  - Handle system has stable funding
+  - PID system is reliably available and maintained
+  - PIDs have an adequate metadata set
+  - PID registration is open to all (vs. paying users only)
+  - PID is machine readable via API
+  - Further developments are downward compatible (with previous updates, content and technical)
+  - Also: What other PID systems capture the same types of data?
