The Digital Archiving Migration Process Cont.
which can assist the archivist in the digital migration of videotape content. SAMMA provides a workﬂow solution which takes the archivist through the migration process to provide a lossless high quality archival ﬁle which can replace the archival master videotape or serve as a robust addition to the endangered videotape collection. SAMMAprep – the SAMMA workﬂow solution begins with the identiﬁcation and organisation of collections within the archive to be migrated. Once the collections to be migrated have been identiﬁed, each master is physically inspected and put through a preparatory phase which not only ensures the physical health of the individual tape, but also initiates a metadata proﬁle attached to a barcode. This preparatory phase is designed to identify any potential problems with the physical condition of the tape prior to migration, create a metadata proﬁle for the asset or tie the asset to a pre-existing metadata proﬁle imported from a previous database, and create a uniﬁed machine readable barcode label which ensures proper asset control through the migration process. Should a tape fail to pass the physical inspection, it should be re-archived until restoration is performed. SAMMAclean – as an optional step in the SAMMA Solutions workﬂow, the SAMMAclean device automatically cleans the tape at faster than real-time speeds, while collecting important metadata regarding both the health of the video signal and the SAMMA Workﬂow Solution health of the physical ical tape.
