39 ISCC International Standard Content Code, a ‘similarity hash’ derived algorithmically from the content itself (see https://iscc.codes). <IDValue> is a sequence comprising the Meta-Code and Content-Code ISCC-UNITSs generated from a digital manifestation of the work, as a variable-length case-insensitive alphanumeric string (or 27 characters including one hyphen if using ISCC v1.0, but this is deprecated). Note alphabetic characters in v1.x ISCCs use Base32 encoding and are conventionally upper case. The ‘ISCC:’ prefix is omitted. Only for use in ONIX 3.0 or later
