Bonjour Alain, Being new to the world of meteorological/oceangraphic data myself recently, I had the same problem you have when reading the various conventions available. Based upon discussions about this matter, and how others are using and interpretating the conventions, I personally have adopted a position whereby the term "should" is regarded as a mandatory requirement. That is to say I interpret "should" as "must".
While I agree that the general definition of "should" would imply something being optional, the general definition also implies a strong sense of obligation. That is to say you must do something unless you have a good reason not to, i.e. I should not kill anyone (I use this as an example of how strongly "should" could be regarded as obligatory, rather than my homicidal tendencies :-) Hope this helps, though I am sure others will also comment.

But If I read the CF documentation http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/cf-conventions-mul ti.html I find "2.1. Filename NetCDF files should have the file name extension ".nc". " For me there is a difference between "must" and "should"?. If i have another suffix than nc, can i be CF compliant?
