Overview of the purpose of the range message and of its file format structure in XML
The ISBN range message is available as a machine-readable xml file with built-in DTD provided for validation.
The file contains up-to-date data from The International ISBN Agency regarding all Registration Group Elements, and the Registrant Element Ranges associated with them. National ISBN Agencies may have more than one Registration Group Element assigned to them and some Registration Group Elements are shared between a number of different national ISBN agencies.
This information provides a computer system with the necessary data to split 13 digit ISBNs issued by any national ISBN agency into the segments of:
[EAN.UCC prefix]-[Registration Group element]-[Registrant element]-[Publication element]-[Check-digit]
Data from this file can also be used to detect ISBNs that are invalid because a particular Registration Group Element within an EAN.UCC Prefix or a specific Registrant Element Range within a Registration Group has yet to be defined.
