AlternativeMusical WorkIdForUsStatutoryReversion

Under the terms of Sections 203 and 304 of the US Copyright Act it is possible for the ownership of a musical work to revert to the composer/writer of the work.

In such circumstances where the musical work that is the subject of this Record is a post-reversion musical work the BWARM data feed sender may choose to identify both “versions” of the musical work.

In such circumstances this Cell contains the proprietary identifier of the data feed sender for the post-reversion work and may be a foreign key to that record in the BWARM data feed sender’s musical works database table (see Figure 2) that enables the data feed sender of the BWARM data feed to point from the pre-reverted musical work which is the subject of this Record to the MusicalWorkRecordId of the post-reversion musical work.

Where a musical works file needs to communicate data about musical works that have undergone US statutory reversions this can be dealt with in two ways:

  1. By creating data about two musical works where one set of data describes the musical work pre-reversion and the other set describes the musical work post-reversion; or

  2. By providing data describing different right shares with different validity periods where one describes the right shares of the musical work pre-reversion and the other set describes the right shares post-reversion.

Given the data structure limitations of most copyright repertoire systems, the common approach is (a). The determination of which parties should receive royalties in relation to a musical work that has reverted which is reported in a BWARM data feed is determined by whether the date of the applicable rights grant (typically a license date) falls before or after the effective date of the reversion, which is the value in the UsStatutoryReversionDate Cell described above.
