DDEX allows to sequence artists using the
SequenceNumber attribute which is available on various composite, including
The code bloc below shows its use on the
DisplayArtist composite. The first
SequenceNumbers should always be 1, followed by 2, 3 etc.
The importance of including such sequence numbers can be shown at the composer pair of John Lennon and Paul McCartney who were listed on the first Beatles album as McCartney/Lennon and on all subsequent albums as Lennon/McCartney.
The sender of DDEX messages – particularly record companies – need to be be aware that if they do not provide a sequence number for
IndirectResourceContributors, the DSP is at liberty to order the artists as they wish (and, potentially, turn Lennon/McCartney to McCartney/Lennon).
The order of
ResourceContributors is of less importance.
