03 Image width in pixels Resource Version Feature Value carries an integer
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>
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)
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
07 Exact download file size in bytes Resource Version Feature Value carries a integer number only (eg 1831023)
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
09 ISCC International Standard Content Code, a ‘similarity hash’ derived algorithmically from the resource content itself (see https://iscc.codes). <IDValue> is the 55-character case-sensitive string (including three hyphens) forming the ISCC of the resource file
