+1. An identifier for the pseudo family (like `dojo` for the [PseudoDojo](http://www.pseudo-dojo.org/) family of potentials.
+2. The type of pseudopotential (`nc`: norm-conserving, `us`: ultrasoft, `paw`: projected  augmented wave)
+3. Details on the level of relativistic effects employed when generating the pseudo (`fr`: Full relativistic, `sr`: Scalar relativistic, `nr`: No relativistic)
+4. The functional for which the pseudopotential was prepared
+5. The version of the pseudopotential construction (with version points replaced by underscores)
+6. The program used to generate the pseudopotential
+7. Some additional comments specifying the pseudopotential.
+   E.g. for PseudoDojo potentials there is usually a `stringent` version
