2.1 Introduction

The message design defined in this standard provides a mechanism for Licensors (typically Music Rights Societies, Audio-visual Rights Societies, and/or Music Publishers) to make rights claims on Musical Works and send these to Licensees (typically Digital Service Providers).  The message design defined in this standard also provides a mechanism for Licensors to accompany, if appropriate, such claims with invoice details. The message design defined in this standard also provides a mechanism for Licensees to provide information on discrepancies they have detected in such rights claims or invoice details.

Such data is provided, in accordance with the overall architecture defined in Part 1, in a series of Records. The order of these Records is defined in the relevant Profile (as documented in a separate Parts of this standard) whereas the syntax and semantics of each Record is defined in this Part 2.
