stdnum.grid

GRid (Global Release Identifier).

The Global Release Identifier is used to identify releases of digital sound recordings and uses the ISO 7064 Mod 37, 36 algorithm to verify the correctness of the number.

stdnum.grid.compact(number: str) → str

Convert the GRid to the minimal representation. This strips the number of any valid separators and removes surrounding whitespace.

stdnum.grid.format(number: str, separator: str = '-') → str

Reformat the number to the standard presentation format.

stdnum.grid.is_valid(number: str) → bool

Check if the number is a valid GRid.

stdnum.grid.validate(number: str) → str

Check if the number is a valid GRid.
