6.6.2 BlockIDs

All Blocks contain a BlockId Cell. BlockIds must be unique within a single Sales/Usage Report. This can be achieved, for example, if the first Block in a Sales/Usage Report has BlockId containing the value 1, the next Block has a BlockID containing the value 2, and so on. Industry standard identifiers such as ISRC, ISWC, ISNI etc. shall not be used as BlockIDs.

This mechanism enables all the Records in a Block to be associated with one another. If, for instance, a Block contains a Head Release, a number of resources and a few usage Records, the BlockId can be used to link the usage Records to the Head Release.
