9.6 Prepare digital files for transfer into Archivematica
Introduction
- Ideally, audiovisual digitization projects will produce digital audio files and/or digital video files that do not require editing before transfer. The goal is to simply catalogue and organize the material before transferring digital files into to Archivematica.
- Manual video and/or audio editing can be incorporated into the workflow if the mezzanine and/or access copy need to altered (.e.g., trimming, cropping, transcoding). In these situations, the material cannot be catalogued until after the editing is complete.
- Procedures are intended to be performed on newly acquired digital files prior to uploading to the Libraries' transfer service.Â
- Procedures can also be performed on previously acquired digital files that Libraries staff have already uploaded to a location on the Libraries' SAN.
Update RAD archival descriptions and ISAAR-CPF authority records
- Use shipping manifest, vendor metadata, digital files, and other sources of information to update archival descriptions. Notable areas include:
- Dates of creation
- Physical description
- Scope and content
- Location of originals
- Availability of other formats
- Terms governing use, reproduction, and publication
- Rights
- Subject access points
- Place access points
- Genre access points
- Name access points (subject)
- Use shipping manifest, vendor metadata, digital files, and other sources of information to update or create archival authority records.
- Update Control Area of all archival descriptions and authority records.
Catalogue audiovisual item and digital copies in PBCore Cataloguing Tool
Download the free PBCore Cataloguing Tool.
- Open the project Excel file and export the data in the PBCore tab to a new CSV file labelled "metadata_draft.csv"
- Open the metadata_draft.csv file in Excel and add any metadata from the archival descriptions or archival authority records. Save the csv file.
- Launch the PBCore Cataloguing Tool and import the metadata_draft.csv file.
- Work with metadata to ensure that PBCore Cataloguing Tool understands that:
- Each work is a PBCore "asset" with multiple "instantiatons."
- Compilations are PBCore "assets" with "sub-assets" and multiple "instantiations."
- Generate metadata.csv file and save in metadata sub-folder.
- Each work is a PBCore "asset" with multiple "instantiatons."
- Export new PBCore metadata file and save as metadata.csv.
- Run script to produce dublin_core.xml and pb_core.xml file?
Produce rights.csv PREMIS metadata file
Use a CSV template.
- Create new rights.csv file in metadata sub-folder.
Organize files and upload to Libraries' transfer service
- Logon to...
- Create a "top-level" folder that will contain all of the desired files and folders to be included in the submission.
- Organize each top-level directory into an Archivematica "standard transfer" that includes metadata, submission documentation, checksums, mezzanine files, and access copies. Refer to the following table for guidance:Â
Top-level directory | |||
Folder | Sub-folder | File | Description |
---|---|---|---|
access | 8-bit (MPEG-4 / H.264) | access copy (data rate capped at 3.5 Mpbs) | |
metadata | submissionDocumentation | dublin_core.xml pb_core.xml Copyright consent form Correspondence | Dublin Core metadata for simple archive bulk import into DSpace PB Core metadata for simple archive bulk import into DSpace Copyright |
metadata.csv rights.csv checksum.md5 | Dublin Core and PB Core metadata for METS file PREMIS rights metadata Checksum files provided by vendors | ||
service | 8-bit (MOV / ProRes 422) | mezzanine copy | |
JPEGs 10-bit uncompressed (MOV / Black Magic YUV v210) | images of source videocassettes preservation master |
Optional: generate new mezzanine and access files
If video editing is necessary, the material must be catalogued in PBCore Cataloguing Tool after new mezzanine and access files are generated.
- Load 10-bit uncompressed MOV file into Vegas project.
- Trip and crop as necessary.
- Render new mezzanine file.
- Render new access copy.
- Catalogue videocassette and digital files in PBCore Cataloguing Tool
