9. Performance Assessment

Table 35 gives the Audio Recording Preservation (ARP) Packager Means and how they are used.

Table 35 – AIM Means and use of Audio Recording Preservation (ARP) Packager.

Means Actions
Performance Assessment Dataset DS1: n Preservation Audio Files.

DS2: n Preservation Audio-Visual Files related to DS1.

DS3: n Restored Audio Files arrays related to DS1 coming from Tape Audio Restoration.

DS4: n Editing Lists related to DS3 coming from Tape Audio Restoration.

DS5: n Irregularity Files related to DS1 coming from Tape Irregularity Classifier.

DS6: n Irregularity Images related to DS5 coming from Tape Irregularity Classifier.

DS7: n Access Copy Files.

DS8: n Preservation Master Files.
Procedure 1.     Feed Packager under Assessment with DS1, DS2, DS3, DS4, DS5 and DS6.

2.     Compare the output Access Copy Files with DS7.

3.     Compare the output Preservation Master Files with DS8.
Evaluation For a given input tuple, verify that:

1.     The output Access Copy Files contain the Restored Audio Files, the Editing List, the Irregularity File and the set of Irregularity Images in a .zip file and is therefore equal to DS7.

2.     The output Preservation Master Files contain the Preservation Audio File, the Preservation Audio-Visual File with the audio of the Preservation Audio File, the Irregularity File, and the Irregularity Images, and is therefore equal to DS8.

An error on any of the output arrays will make the Packager under test not conformant.
