Dear,

Thank you for your explanations.
And sorry if I am still slow to understand.

I understand this. :-)

Ok, but for example this convention about CRAN is not consistent with
the importer. :-)
  guix import cran corpcor -r
fills the license field with (license gpl3+) and not (license license:gpl3+)

In other words, why the cran.scm needs a prefix for the license field?

Ok.
But there is a convention or an explanation why some packages use a
prefix e.g. cran.scm and other not e.g scsi.scm?

Thank you again for your explanations.

Best regards,
