Dear list,A CF-conformal NetCDF file should be as self-describing as possible. URIs/PIDs poitining to external data sources are problematic in this context. However, IDs pointing to external data sources were already discussed for taxa in the CF Trac Ticket #99 "Taxon Names and Identifiers" (https://cf-trac.llnl.gov/trac/ticket/99).
Let's assume we have a long description of quality control measures performed resulting in N possible quality states for a NetCDF variable. The full description could be part of a peer-reviewed paper or grey literature (with assigned PID). However, it is too long to be included in the attribute "description" of the quality/status flag variable. One solution would be to add a brief description of the quality states to the quality_flag/status_flag variable and point to the external full description via it's PID.
What is your opinion on this?This is not a request for a feature but rather meant to collect some opinions on this topic. It is somehow related to the request of a global PID attribute in CF GitHub Issue 160 "Add attribute citation_id" (https://github.com/cf-convention/cf-conventions/issues/160).
