During this Part, the Archive conducts a final appraisal of the records involved in the Ingest Project. It ensures that the records in the newly formed AIPs are the records described in the Submission Agreement and that they have the proper metadata associated with them. If the AIP does not contain the correct records, the Archive rejects the records and notifies the Producer to generate a new SIP for the affected records. If the records in the AIP do not have the proper metadata, the Archive determines if they can be added with a reasonable amount of effort. If this effort is too great, the Archive rejects the affected records. Usually, the Archive checks a sample of records involved in the Ingest Project. The appropriate rate of sampling depends on the circumstances of the Archive and individual Ingest Projects.
