Record companies sometimes require that a DSP makes available a Release under terms and conditions that may change over time. For example, the recommended retail price may change before, during, or after a specific event (Christmas, a sports event, etc).
In such circumstances the
DealList section needs to contain several deals the dates for which are consecutive without any gaps, i.e. as soon as one deal ends the other deal starts. This can be effected with both dates and date-times. If two subsequent Periods form a continuum (i.e. with no break in-between) there are two ways to express this:
- if using dates, the
EndDateof the first
ValidityPeriodmust be one day before the
StartDateof the second
- if using datetimes, the
EndDateTimeof the first
ValidityPeriodmust be the same string as the
StartDateTimeof the second
In both examples, below, the price of the Release increases from 500 Islandic Króna to 1,000 Islandic Króna at midnight between 31st January and 1st February 2018:
Note that it is not recommended to use 2017-01-31T24:00:00Z and 2018-02-01T00:00:00Z as the end of the first ReleaseDeal and the start of the second ReleaseDeal even if they denote the same moment in time. Instead, the same string should be used for both datetimes.
