Impact date

One of the crucial aspects of the MEAD standard is that it allows a record company to communicate an “impact date” (i.e. the date when a track started receiving a significant amount of airplay) to a DSP. Impact dates are especially useful for helping music discovery on smart speakers and other devices with no screen.

The impact date is communicated in the Usage composite as shown below:

    <MetadataSourceReference>U1</MetadataSourceReference>
    <UsageDate>1990-10-01</UsageDate>
    <Description>ImpactDate</Description>
  </Usage>
</ResourceInformation>

 However, given the importance of the impact date, the impact date will be communicated in a separate ImpactDate composite, in the next version of the MEAD standard.
