7.1 General rules

When using the Profiles defined in this part of the MWN standard the following rules apply:

  1. Regardless of the Profile, a MusicalWorkClaimNotificationMessage shall contain data describing at least one MusicalWork defined in the WorkList composite.

  1. The values for the ProfileId tags set out in the following clauses do not contain any white-space characters.

  1. All identifiers shall be globally unique. For proprietary identifiers this uniqueness shall be achieved by communicating the identifier with the relevant namespace.

  1. The MessageId element shall be, in combination with the DDEX Party ID of the message sender, globally unique. Thus, a message sender shall never re-use a MessageId.

  1. All identifiers with a published syntax shall conform to that syntax.

  1. It is only permissible to communicate a UserDefinedValue attribute if a Namespace attribute is provided alongside it.

  1. Percentages shall be provided as decimals with, e.g., 25.5 representing 25.5%.

  1. In accordance with Clause 7.7 of Part 1 of the MWN standard, it is recommended to use the new Territory composite to communicate territory data.

  1. Any data fields or composites not defined as being mandatory for a specific Profile may still be used by the message sender, unless explicitly forbidden by the Profile. The message recipient may, however, discard any such information at its own discretion.
