Name	Definition
OriginalSpeedStandard	Speed standard applied to the tape recorder during the digitisation of an open-reel tape. It can be one of the following values: 0.9375, 1.875, 3.75, 7.5, 15, 30. These values are in inch per seconds (ips). This field is optional.
OriginalEqualisationStandard	Equalisation standard applied to the tape recorder during the digitisation of an open-reel tape. It can be one of the following values: “IEC”, “IEC1”, “IEC2”. The notation refers to documents [18,19]. The association with OriginalSpeedStandard shall be compliant to the values indicated in [18,19]. This field is optional.
OriginalSamplingFrequency	UUID [3] that identifies a Restoration.
Restorations	List of restorations objects. Each object shall have at least the following fields: RestorationID, RestoredAudioFileURI, PreservationAudioFileStart, PreservationAudioFileEnd, AppliedSamplingFrequency, ReadingBackwards.
RestorationID	UUID [7] that identifies a Restoration.
PreservationAudioFileStart	Time Label indicating the instant of the Preservation Audio File when the restoration starts.
PreservationAudioFileEnd	Time Label indicating the instant of the Preservation Audio File when the restoration ends.
RestoredAudioFileURI	URI of a Restored Audio File.
ReadingBackwords	Boolean value indicating if the audio signal direction has been inverted during the restoration process.
AppliedSpeedStandard	Speed standard applied during the restoration process. It can be one of the following values: 0.9375, 1.875, 3.75, 7.5, 15, 30. These values are in inch per seconds (ips). This field is optional.
AppliedSamplingFrequency	Specifies the sampling frequency of the Restored Audio File. This field is mandatory.
AppliedEqualisationStandard	Equalisation standard applied during the restoration process. It can be one of the following values: “IEC”, “IEC1”, “IEC2”. The notation refers to documents [18,19]. The association with AppliedSpeedStandard shall be compliant to the values indicated in [18,19].
