Last updated in issue 62
Value Description Notes Issue number Modified in Issue
01 File format Resource Version Feature Value carries a code from List 178 10 11
02 Image height in pixels Resource Version Feature Value carries an integer 10 11
03 Image width in pixels Resource Version Feature Value carries an integer 10 11
04 Filename Resource Version Feature Value carries the filename of the supporting resource, necessary only when it is different from the last part of the path provided in <ResourceLink> 11 44
05 Approximate download file size in megabytes Resource Version Feature Value carries a decimal number only, suggested no more than 2 or 3 significant digits (eg 1.7, not 1.7462 or 1.75MB) 11 17
06 MD5 hash value MD5 hash value of the resource file. <ResourceVersionFeatureValue> should contain the 128-bit digest value (as 32 hexadecimal digits). Can be used as a cryptographic check on the integrity of a resource after it has been retrieved 12
07 Exact download file size in bytes Resource Version Feature Value carries a integer number only (eg 1831023) 17
08 SHA-256 hash value SHA-256 hash value of the resource file. <ResourceVersionFeatureValue> should contain the 256-bit digest value (as 64 hexadecimal digits). Can be used as a cryptographic check on the integrity of a resource after it has been retrieved 28
09 ISCC International Standard Content Code, a ‘similarity hash’ derived algorithmically from the resource content itself (see https://iscc.codes). <IDValue> is the ISCC-CODE generated from a digital manifestation of the work, as a variable-length case-insensitive alphanumeric string (or 55 characters including three hyphens 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 50 62
