Metadata produced by the software follow Argo conventions (as in reference tables provided by the Argo vocabulary server)

This guideline requires that when the software produces some data, the metadata attached should follow the Argo conventions.

For instance, if a software produces a salinity variable, it should be named `PSAL`.

The Argo conventions and vocabulary are encoded in a collection of reference tables and associated values (and possible mapping between them).

More information on these data are available here: https://www.argodatamgt.org/ArgoVocabulary.html

Following this guideline can be _hard coded_ in the codebase. However, the software should use the vocabulary server whenever relevant to ensure up-to-date information (see guideline #60 )
